- warning26 5y agoI love their wind direction and speed visualization -- it does such a good job conveying exactly what's happening. The AQI overlay is really interesting to combine with it, since it can give you an idea why certain pockets of air are lower/higher quality.

- themodelplumber 5y agoThey are running an impressive show all around, check out their webcam embeds and API, great for spotting fires and things, plus they have their own online community forum. Their mobile app is really good too, includes offline map capabilities, and I take it on hikes for tracking.
- ortusdux 5y agoThey have been my preferred weather source for a few years now. Forecasting is spotty in my area, but they have a feature where you can quickly compare 4 weather models, which tends to give a good overview. They also have my favorite android widget.
- sva_ 5y ago> but they have a feature where you can quickly compare 4 weather models meteoblue.com offers 18 models if you click on 'MultiModel'. I found them to be very reliable. windy.com is cool though, respect to the Czech founder https://en.wikipedia.org/wiki/Ivo_Luka%C4%8Dovi%C4%8D https://en.wikipedia.org/wiki/Ivo_Luka%C4%8Dovi%C4%8D

- silisili 5y agoI love Windy. It's great for anyone who goes surf fishing. Helps avoid the frustrating days.
- ourguile 5y agoAbsolutely love this site for forecasting weather events in my area. Not sure what I would do without it at this point.
- evilpie 5y agoI have been using the similar site https://www.ventusky.com https://www.ventusky.com for a few years now.
- glxxyz 5y agoAnother similar one: https://earth.nullschool.net/ https://earth.nullschool.net/
- morganvachon 5y agoMy journey with weather mapping sites went in reverse order from this thread: Years ago when I ran a local weather blog I discovered the Nullschool site, then a few years later VentuSky, then Windy. I don't do the blog anymore but I still rely on Windy for visualizing weather conditions.
- ChrisMarshallNY 5y agoThey look like clones. What's the difference?
- jonahbenton 5y agoThere are a LOT of weather geeks around the world. Different folks, different origin stories.
- tokyokawasemi 5y agoEarth.nullschool is the original one.
- minimalist 5y agoThis is correct and it is open souce software unlike the commercial derivatives, which do add their own value, granted.
- aeharding 5y agoAnother one: https://www.windfinder.com https://www.windfinder.com
- rrix2 5y agoover the past few years my use of weather apps + forecasting has really been improved by reading alongside them the local NWS office's "area forecast discussion"which is published multiple times a day by the station's meteorologists: https://www.wrh.noaa.gov/total_forecast/getprod.php?new&wfo=sew&sid=SEW&pil=AFD https://www.wrh.noaa.gov/total_forecast/getprod.php?new&wfo=... It's really great to be able to contextualize the state of a Windy map, for example especially in Seattle where the weather patterns are tightly influenced by the Olympic mountains and other local conditions which these global maps usually fail to capture or express well. Windy is impressive stuff but looking is half the battle with these maps, wind directions and "that weather blob is orange right now" only really go so far when your weather area's geography isn't simple; in fact, i think that the older static Weather Channel style maps which expressed the pressure gradients and fronts better and helped you build a model of what the weather is doing rather than which way the wind is blowing. (see https://s3.us-east-2.amazonaws.com/journeynorth.org/images/graphics/weather/2014/aborn0305.jpg https://s3.us-east-2.amazonaws.com/journeynorth.org/images/g... for an example)
- c54 5y agoHere's the same for the SF Bay area for those interested (took some poking around to find it, basically MTR is the monterey/bay area weather center so I tweaked the URL params to match) https://www.wrh.noaa.gov/total_forecast/getprod.php?new&wfo=mtr&sid=MTR&pil=AFD# https://www.wrh.noaa.gov/total_forecast/getprod.php?new&wfo=...
- rrix2 5y agoYup! And in general, you can click your location on https://www.weather.gov/ https://www.weather.gov/ 's image map, and it'll redirect you to the local office URL which is the same 3 letter code: https://www.weather.gov/mtr/ https://www.weather.gov/mtr/ and there is a link to the AFD in the "Text Product Selector" on the page!
- ctvo 5y agoWindy has all of that. A quick glance at the layer menu on the right of the map shows how to toggle that and more.
- thetimbanks 5y agoI've been using this for a few years to plan out sailing trips. It has been very helpful and accurate to predict wind conditions.
- sgarman 5y agoThis site has been popular in some aviation sports like paragliding. At least from my casual observations.
- SCAQTony 5y agoI use it for surf forecasting. When you click on "waves" icon, the menu extends and there is an icon for a surfer. Click the surfer and not only do you get a different "heat" map but wherever you click will give you the swell for that location.
- mig39 5y agoI've been using Windy to keep an eye on Hurricane Larry and my friends and relatives in St. John's, Newfoundland. Looks like they're about to be clobbered in a few hours.
- robertsdionne 5y agohttps://earth.nullschool.net/ https://earth.nullschool.net/
- browningstreet 5y agoThis one's new to me. Never heard of it before. Thanks!
- Qi_ 5y agoRuns very smoothly on Safari on iPhone 6S! An impressive job by the devs.
- mmaunder 5y agoWindy is great. The map is appealing, but be sure to check out the forecast view for a particular location. Also make sure you try different locations. I'm in the Salish Sea on Orcas Island in the San Juans and because we have a lot of topography here mixed with ocean, we have a lot of local effects, contour winds and so on and there are big differences between locations. Also note that Windy can get it wrong. I grew up in Cape Town and forecasting there is easy compared to here because it's the tip of Africa surrounded by Atlantic and Indian Ocean. Here it's very mixed with land, sea, big 11,000ft mountain ranges like the Olympics and so on and this region is hard to forecast. For where we are, the forecasts - and Windy's map specifically - is wrong fairly often. A trick that a lot of folks don't know about is using ATIS, AWOS or ASOS at a local airport or airfield. If you want to know what the weather is at a given location, find a nearby airport, get their ATIS (or AWOS or ASOS) phone number and you can call and get a real-time report that is extremely accurate. I do this for KORS, our local airfield all the time. You can get this data off Foreflight although I'm sure there are plenty of free alternatives. Obviously it's current weather, not forecast, but it's often helpful.
- themodelplumber 5y agoYou live in a beautiful area. I grew up scouting around there...on one trip we were invited to embark & leave Eastsound earlier than anticipated because a couple of our members decided to "casually" lift some cigars from a store there (IIRC). xD Thanks for the ATIS info too. I wonder if it's the same type of message I hear on non-noaa VHF from nearby.
- mmaunder 5y agoThanks - I'd forgotten about the marine VHF reports. Rarely listen to them, and I should. LOL! Trust me Orcas has plenty of scandal that's worse than that. I'm sure less than half the island has all your social security numbers memorized.
- xxpor 5y agoIf you're in the US, you can get METARs from aviationweather.gov: https://www.aviationweather.gov/metar/data?ids=KSEA&format=decoded&date=&hours=0 https://www.aviationweather.gov/metar/data?ids=KSEA&format=d...
- spoonjim 5y agoThis looks like the wind hits the West Coast of the United States and "turns" southwards. Is that accurate? If so, what causes it to do that?
- lbrindze 5y agoHigh pressure over the north east pacific combined with the Coriolis effect. Also the land sea border has a big influence here in this case in particular.
- sealaska 5y agoWindy is fantastic. But, I'm curious if there are any apps or weather models that give probability distributions? Telling me that it is going to blow 10 mph is useful, but telling me, for example, that there is a 60% chance that there will be a 10 mph wind and a 40% chance that the wind will blow at 15 mph seems more in line with how I would naively assume weather forecasting works. Right now, the ECMWF [0] model in Windy shows 6 mph winds gusting to 30 mph for my area (SE Alaska, with lots of mountains and fiords, so a area that is gusty and hard to predict by nature). It almost feels like they're throwing their hands up in the air and admitting that they have no idea what the wind will actually do today. Which, is fine, if that's the case. I just wish consumer weather forecasts did a better job communicating probabilities and uncertainties instead of spitting out a single value. [0] https://www.ecmwf.int/ https://www.ecmwf.int/
- shoyer 5y agoECMWF makes probabilistic forecasts, in the form of an ensemble of 50 IID examples. So this is mostly matter of Windy figuring out how to put that information into their UI.
- sealaska 5y agoThanks for the reply. It sounds like you have a much better grasp of these things than I do. So, when clients like windy forecast "10 knots east gusting to 20" for ECMWF, do you know if those numbers are directly copied and pasted from the ECMWF model, or do clients take the probabilistic forecast model and make some sort of average prediction that they display? I'm very interested in how clients like windy go from a probibilistic forecast model to a singular hard number. Unless this is something built-in to ECMWF itself.
- transportguy 5y agoGFS takes a simple average of the ensembles for their avg model, I believe. The biggest problem is that you can't use statistics like you normally would in meteorology. Predictions are actually very good for knowing WHAT happens to a weather system, but not WHERE it happens. I work in the sailing space, so this is what happens there: A racing offshore sailor would consider a variety of models and ensembles. Then they would consider the various possibilities for the weather systems and fronts (e.g. front crosses your path +/-5% East/West within a +/-3h gap). A sailor would then avoid any possible dangerous situations, and pick a path that on the most number of models gives them an optimal wind. It is both an art and a science. If you compare the results of sailors who compete in offshore competitions (such as the Vendee globe), where the boats are all constructed in very similar ways, you'll see that the best sailors consistently get good results, and that is based on good meteorology and a good gain to risk ratio for route choice.
- geuis 5y agoThis page needs some non-scrollable borders for mobile. Once you scroll down a bit into the map, it’s nearly impossible to get back to the browser ui controls
- aeharding 5y agowindy.com is great for forecasts, but you have to be careful of the model used for certain sports. (For example, the NAM model can be more accurate for low wind gusts.) In my spare time over the last couple weeks I've been building a PWA for paramotor pilots to better visualize winds aloft: https://ppg.report https://ppg.report. Wind modeling - especially for aviation - is really an interesting subject. The main API I use at ppg.report is https://rucsoundings.noaa.gov/ https://rucsoundings.noaa.gov/, lots fun to learn about (CIN, CAPE, the historical "soundings" manually reported from aircraft and balloons, versus the modern ones automatically pulling data from commercial flights.)
- 35mm 5y agoDoes anyone know what Windy’s business model is? I’m just curious because it’s not clear to me.
- sealaska 5y agoThey have a premium subscription with higher-granularity forecasts. [0] [0] https://community.windy.com/topic/11552/we-are-launching-windy-premium-even-better-forecast-for-just-price-of-a-lunch https://community.windy.com/topic/11552/we-are-launching-win...
- bujak300 5y agoThe business model is that the founder is co-owner of seznam.cz ("czech google/yandex")
- tluyben2 5y agoI was on a HK island when Mankut hit and Windy was incredible. It was much easier to see when what was going to hit than the local news. For the village we were staying, the local news said 12 (noon) was the worst, but it was clear in windy that would be hours later. As this thing did a lot of damage, it was kind of nice to be able to predict it well.
- killjoywashere 5y agoWindy is popular on Guam. Massive storms come through and usually demolish a chunk of Taiwan, but rarely do much damage on Guam. But it's always close. Windy gives a sense of how much wind we'll get with a very fine grain that's quite intuitive.
- wayneftw 5y agoThis is also a PWA that you can add to your home screen in iOS for a nice full screen view.
- danellis 5y agoI wonder how it would look if the speed of the arrows matched the speed of the wind. Perhaps they'd be too slow to be useful when zoomed out.
- mhandley 5y agoI also really like https://earth.nullschool.net/#current/ https://earth.nullschool.net/#current/ It's not so useful as a forecast, but you can move around the world and see everything so well. Take a look at the winds in the Southern Ocean for example, and you can see why it's so tough to sail there.
- capt_skippy 5y agoI really like Windy's base maps. How did they generate them and what's the style?
- RivieraKid 5y agoThey're using Mapy.cz. Same location in Mapy.cz and Google Maps: https://mapy.cz/turisticka?x=14.1857611&y=49.9310438&z=14 https://mapy.cz/turisticka?x=14.1857611&y=49.9310438&z=14 https://www.google.com/maps/@49.931472,14.185431,14z https://www.google.com/maps/@49.931472,14.185431,14z
- capt_skippy 5y agoSo pardon my ignorance in all things GIS, but it looks like Mapy.cz serves the tiles which are based on OpenStreetMap. On that Mapy.cz site, there is no style that is similar to Windy. The maps I see are "Basic", "Traffic", "Outdoor", etc. I'm interested in the grey/outlines basemap like this: https://www.windy.com/-Weather-radar-radar?radar,50.310,1.159,7 https://www.windy.com/-Weather-radar-radar?radar,50.310,1.15... . The shading around the coastlines in particular is exquisite. How did they generate this grey basemap? Does Mapy.cz offer the tools to generate such a map or do they just host the tiles?
- RivieraKid 5y agoOh, I thought you meant the map which is visible if you zoom closer on Windy. The gray map is probably custom made by Windy.
- jq-r 5y agoActually that is an excellent map, thanks!
- c0nsumer 5y agoCheck out the stand-alone Windy Maps app. It's basically their OSM-based map layer, all by itself. It's a decently handy lightweight compliment to other heavier OSM tools like OsmAnd and GaiaGPS.
- MayorMonty 5y agoI imagine something like this could be a fantastic tool to teach about differential equations and their applications. Just looking at you can see specific hallmarks (sources and sinks), and how that sort of analysis can have super-cool uses. Does meterology use differential equations to model wind?
- transportguy 5y agoyes, but it takes at least a degree to even understand the basics
- lbrindze 5y agoAll of the big agency (NWS, ECMWF, ICON, etc.) use physical models to create the large gridded forecast products. These models work by solving differential equations so your intuition here is spot on!
- fidgetspinner 5y agoAsa paragliding pilot/speedflyer, I absolutely love this app/site. We use it all the time!
- adanto6840 5y agoAwesome. Have actually been looking for precisely this kind of data for potential use in a game that we're currently developing. Thrilled to see what appears to be a solid API too, going to dive right in. One thing I don't see mentioned, or I may just be unfamiliar with the terminology (and haven't dug much into the docs yet), is how exactly the 'map data' API (ie not the point-location API) works/what format the data is returned in, or if it's more expected to be used as an "embed". My ideal, based on our current code/implementation thus far, would be to be able to supply a lat/lon coordinate bounding box & have it respond with the data in GeoTIFF format with multiple bands, one for each "data-set". If anyone at Windy is here & might potentially be interested in discussing our game & the game's use-case for the data, please definitely feel free to reach out -- email in profile. :)
- transportguy 5y agoThere are already games that use live wind data (see e.g. virtual regatta). They source data directly from NOAA/GFS rather than from an aggregator like windy
- heroHACK17 5y agoVery cool
- bscphil 5y agoThe wind animation doesn't work at all for me in Firefox (on Linux, version 91). I see a few large animation "sheets" where the wind is moving in the same direction, depending on where on the map I look. Works in Chromium. Anyone else have this problem? Screenshot: https://i.imgur.com/eLyQa6X.jpg https://i.imgur.com/eLyQa6X.jpg
- 10GBps 5y agoWeird. I'm using Firefox 91.0.2 on Ubuntu 20.04 and it works fine. Maybe try opening it in a new empty profile and see if it works?
- bscphil 5y agoI did end up getting it to work, left a comment here if you're interested: https://news.ycombinator.com/item?id=28488599 https://news.ycombinator.com/item?id=28488599
- davidjade 5y agoDoesn't work for me on Firefox in Windows either. I've tried a number of things and it seems it just doesn't work on Firefox at all.

- tunap 5y agoEven before 2017, I recall reading here about... windy.tv(?) or some sort of odd extension. Shortcut has been in my toolbar, url updated 1 or 2 x's, since. A great resource when travelling by road looking to avoid high winds, rain, sleet & snow.
- hellbannedguy 5y agoThere's also MyRadar, but this looks more accurate?
- zxcvbn4038 5y agoThis is very cool, I’m guessing that Bismarck, North Dakota is the place to be if you are wind farming, looks like a lot of air is being funneled past it. Things get interesting around the Rocky Mountains in general.
- Englestone 5y agoSo Simple. Brilliant
- jzwinck 5y agoI used Windy when planning a bicycle tour. It told me the wind would be mostly from the east, so I began my trip in the east and enjoyed 1300 km with a tailwind. The same idea could apply to long distance running or hiking, canoeing, and other non-wind sports.
- hugoromano 5y agoI was paying for it, but didn't renew the subscription, this year in 90 days that I needed forecast was way off in 42 of them, and trying all their different model offers. Maybe next year I will resubscribe, depending how their models forecast over Fall and Winter.
- sealaska 5y agoAre you using a different weather app or website that is more accurate? My understanding is that windy primarily just shows data from different forecast models, so isn't your issue really with the third-party models, not with Windy's weather client?
- hugoromano 5y agoMy grandfather was a meteorologist (taught me forecast based observation and weather station data), and I am also a first officer half of the year (as well have education in modelling for navigation). This year was rough with modelling. I use Windy to validate my forecast and navigation decisions at sea. As we sail, anemometer readings are crosscheck with the forecast from windy and mine, and windy didn't go well. Sometimes paper and pencil do a great job. I started using Windy (windyty.com) in 2016, and until 2020 forecast was quite good, my takeaway is that maybe Climate Change could make the job of weather forecasting much harder.
- sealaska 5y agoHuh, fascinating stuff. Do you have any recommended resources for anyone looking to learn more about "paper-and-pencil" forecasting or marine weather forecasting in general?
- bujak300 5y agoThe weather models themselves are evolving - there was a big upgrade of GFS last year for example

- aasasd 5y agoI occasionally meditated for a bit upon a similar map on Yandex Weather—finally understood what the deal with Siberia is. Like, in spring it's way below zero around Mongolia, while it's on the same latitude as Black Sea where it can already be +20°C. Well, turns out I can clearly see warm air moving from the Atlantic eastwards—until it hits the Urals and stops, and everything beyond that is frozen tundra. Warm air from the Pacific somehow barely reaches Siberia, deciding to turn east or west instead. Really nice to just watch this on the screen in realtime. Also in the rain map, it's fun to look at huge clouds spanning entire Europe. Especially if my city is precisely in a small window of clear skies amid the rains.
- ArlenBales 5y agoI live north of Sacramento. This summer I found NOAA's GOES-17 satellite imagery to be the easiest and most accurate method in determining where wildfire smoke would move. https://www.star.nesdis.noaa.gov/GOES/sector_band.php?sat=G17§or=pnw&band=GEOCOLOR&length=48 https://www.star.nesdis.noaa.gov/GOES/sector_band.php?sat=G1...

- yutyut 5y agoI use Windy fairly regularly for military flight planning. Nice tool to get an idea of when to launch to hit a timeline/TOT.
- grapist420 5y agoIncredibly petty: after a mobile pan, keep the lengths on the arrows pls
- thecaio 5y agoAny kite surfers? How have you found Windy for spotting decent places to surf? I’m a fan of Windy but sometimes find it a bit “lowres” in the sense that it does a good job on translating wind direction/force in broader, more general areas while it’s hit and miss for specific spots (eg beaches or nooks). POVs?
- bujak300 5y agoThe highest resolution model Arome could help but at that level your intuition and experience is essential. BTW The most notable kitesurfer would be the founder and CEO of windy.
- yardshop 5y agoWindy looks great, I will add it to my daily weather websites. My primary visual weather site is the National Weather Service Enhanced Data Display. https://preview.weather.gov/edd https://preview.weather.gov/edd It's been "*Experimental*" for several years, and the site looks kind of dated, but it provides a useful visualization of radar, satellite, tropical storms, etc, plus it runs on my old PC! =) I also like the NWS Hourly Graph to give a better idea of for example when it's going to start or stop raining or go below freezing on a given day. This is the forecast page for my area: https://forecast.weather.gov/MapClick.php?lat=43.7445&lon=-70.4253 https://forecast.weather.gov/MapClick.php?lat=43.7445&lon=-7... Put in your own zip code, or type in town and state (sorry, just US). Then click "Hourly Weather Forecast" below the daily descriptions to get this: https://forecast.weather.gov/MapClick.php?lat=43.7445&lon=-70.4253&FcstType=graphical https://forecast.weather.gov/MapClick.php?lat=43.7445&lon=-7... There's no location picker on that page though.

- vmception 5y agoNow if only they can resist the temptation to not fuck up their site with an obligatory unnecessary redesign Windy’s whole value add can be “not WeatherUnderground or Darksky”
- firecall 5y agoWow! Damn, that's a fast site! It's a amazing!
- orangepurple 5y agoI attempted to use Windy to judge surfing conditions on Oahu but the current conditions and forecast are never accurate. They might as well be randomly generated.
- orangepurple 5y agoIs there an API to get high resolution 3D volumetric data of storm systems?
- OneEyedRobot 5y agoGood site. I like to watch the current wind reports. Add that together with twitter reports and flightradar24 and you can actually get some idea what a wildfire is doing. It's an area where government and the local news are essentially useless.
- sojournerc 5y agoLocal emergency dispatch can be another great source. This is a great site for dispatch streams. They often have ftac channels too where the firefighters will be communicating. https://www.broadcastify.com/ https://www.broadcastify.com/
- hnburnsy 5y agoIt's like what Weather Underground used to be like.
- robbrown451 5y agoRandom observation: nowhere is 60 degrees F. I'm looking at San Francisco, as well as Portland and Seattle, all of which the temperature is right around 60. No matter how much I zoom in or out, there are dozens of 59s and 61s, but no 60. Curious why. It can't be coincidence based on how many I looked at.
- dhon_ 5y ago15C is 59F, 16C is 60.8F so I'd say using integer Celcius and converting to Fahrenheit
- brantonb 5y agoMy guess is the data is stored in Celsius but displayed in Fahrenheit. 15C = 59F 16C = 60.8F
- mmillin 5y agoThis is likely due to the source data being vended in whole number increments in degrees Celsius. Converting between Celsius and Fahrenheit using only whole numbers would not allow for 60 to show up (it is between 15 and 16 degrees C, which would convert to 59 and 61). There was a large story around this same issue in the Apple weather app, not showing 69 degrees F prior to iOS 15.
- nbombdropper 5y agoHow is something so moronic all the way at the top of HN for HOURS. Are you all fucking retards who didn't know where the wind goes?
- mickael-kerjean 5y agowindy is absolutely brilliant and has become the first app I opened whenever I go sailing (aka almost every week)
- H8crilA 5y agoReminder that weather forecast apps/websites/anything are pretty much all just different UIs for the same underlying global forecasting models. With the NOAA's GFS being the most widely known one. You can find historic forecasts on NOAA's website going decades back.
- counters 5y agoNot all of them. But many are. It's important to be skeptical of claims made about th novelty and quality of weather forecasts from new/unknown players.

- algo_trader 5y agoOff topic: I am interested in off-shore solar resources. Are there raw historic datasets or nice visualization for solar irradiation including over seas and oceans ?
- lbrindze 5y agoYou may be interested in era5 data for historical reanalysis. This is published by the ECMWF and is available for free. I’m pretty sure it has solar irradiance data but I’m not certain. You can also get NCAR reanalysis and other model reanalysis products through the NWS[2]. For visualizing gridded data products you can use panoply[3]. If you just care about GRIBS zyGrib works pretty well too.

- TrisQuinoline 5y agoThere is a startup in Norway called Glint Solar that may help. They serve the floating solar industry with geospatial tools and data, both on reservoirs and offshore. If you can expand a bit on your questions, there may be more resources to point to.

- bujak300 5y agoWindy has multiple models which is great to check how reliable the forecast is - if they diverge then its a clue. In general, the forecasts are great where there is a lot of good input data, like in western Europe and around the Alps. In eastern europe and on the ocean the forecasts can be way off. This is a risk because the pretty graphics and high time resolution somehow associate with precise forecasts.
- londons_explore 5y agoI wish weather forecasters would be more upfront about the accuracy of their forecast. For example "Our rain/no rain 2 day in advance forecast for Seattle was accurate 280 days last year". If all providers published that, I would be able to get my weather from the best forecaster for my area rather than guessing. Bonus points if there is a more scientifically rigorous metric to compare by that they all publish.
- kaixi 5y agoWhere does Windy's data come from?
- zevv 5y agoWhat causes this huge plot of very bad air in the middle of Russia near 63.597820342465404, 112.49690168386316?
- doyoufeelit 5y agoJust reading the name of this site makes me want to fart.
- max_ 5y agoWhere can I learn about the most effective algorithms for forecasting weather?
- c0nsumer 5y agoTheir stand-alone map application Windy Maps is pretty darn nice too. It's a really nice compliment to OsmAnd and GaiaGPS for viewing OSM data, and they've done a good job showing relations which helps illustrate cycling and hiking routes.
- spydx 5y agomy fav weather website is https://www.yr.no/ https://www.yr.no/ the name means very light rain.
- webXL 5y agoSuper cool. Reminds me of https://zoom.earth/ https://zoom.earth/ (https://news.ycombinator.com/item?id=23901252 https://news.ycombinator.com/item?id=23901252) which was really useful recently to gauge wildfire smoke patterns.
- bori5 5y agoIt’s a cool app but I wonder why there’s no way to change font size, even on iPad when my eyes are waking up or other low light situation it can be hard to read the forecast panel in landscape mode etc..
- mukundesh 5y agoLove windy.com, it is great for big weather events, but I have found it going a bit off for day-to-day weather...
- Syzygies 5y agoOther than the canonical "Do I bring an umbrella?" we have one actionable need for precise weather forecasting: In hot weather I have outfit our California house with an assortment of commercial (quiet whole-house exhaust) and homebuilt (computer fan arrays in each window) fans. We rarely use air conditioning even in extreme heat, instead waiting till outdoor air is cooler than inside air to open up the house overnight. It's important to hang box fans between rooms to stir the air as much as possible; one is storing coolth in the walls. People are always surprised we're not on AC when they come inside the next afternoon. As we're both on east coast schedules I sometimes have to set an alarm to get up and open up the house. This is guesswork. Better forecasting would really help. I don't see any multimodel tools in any of these paid apps that give me a better view, zooming in on this precise question, than a generic hourly forecast by the usual suspects. (New construction near us forces a reliance on AC. One would think that in regions with good daily temperature swings, designing a house like a water-cooled computer would make sense. We should be seeing as many rooftop radiators as solar panels. Not a thing...)
- Grustaf 5y agoOutdoor sports is a big one. For kite and wind surfing, you want a lot of wind, for sailing moderate winds and for golf or wakeboard you want no wind.
- thecyborganizer 5y agoIsn't a rooftop water-cooling radiator just a swamp cooler? Common in dry climates.
