I like data like this - it reminds me of the pleasant places maps[1]. That said - you have to be wary of both types of maps because it doesn't take into account other potentially annoying factors. The biggest being humidity - there's a huge difference between 90 degree phoenix and 90 degree miami. Then there's rainfall, and one a lot of people don't think about - wind. To add - if you're thinking about seriously comparing two climates, check out this comparison tool [2]. Has any metric you can dream of charted together. 1 - https://kellegous.com/j/2014/02/03/pleasant-places/ https://kellegous.com/j/2014/02/03/pleasant-places/ 2 - https://outflux.net/weather/noaa/index.php https://outflux.net/weather/noaa/index.php

Yeah this paints most of the Southwest as having a worse climate than where I live, which... yeah, for anyone who hates humidity (which is most people, I think?), that's not remotely true. I'd take 95F and bone dry over 82F and soaking-wet air, any day. Happily.

  Same. I'm moving from FL to the SW this year. People see our summer weather - 88hi, 78 low almost every day and think it's perfect. It's not, and it feels gross down to about 72 degrees because of the suffocating humidity.

    I thought we had humid air in Montreal, literally living on an island, and to some extent it's true, but when I went down to Florida did I understand what humidity can make you feel like. Was there mid-August, some days were brutal.

  Same with cold I would take dry non windy -10F over humid windy 30F any day.

    Moved from Colorado (down to -40 in the winter) to east Texas as a kid. Went outside and was told it was mid 30F's. Did not believe they because it felt way colder. These days I am used to it and wear short sleeves down to about 0 to -10F and watch the minds of everyone go WTF is he on. Had I don't know how many people try to donate me jackets while out walking. (Western AR now but it is the same as east Texas for climate.)

Hmm, I can probably incorporate humidity data without too much trouble. Is there a standard way to calculate a "feels like" temperature using humidity? btw, thanks for reminding me of the pleasant places map -- I think it must have been an unconscious influence on this.

  The calculation from the NWS: https://www.weather.gov/epz/wxcalc_heatindex https://www.weather.gov/epz/wxcalc_heatindex (see the linked PDF[1]) Given an air temperature (T) in °F and a relative humidity (rh). Indexheat = − 42.379 + (2.04901523 × T) + (10.14333127 × rh) − (0.22475541 × T × rh) − (6.83783×10−3×T^2) − (5.481717 × 10−2 × rh^2) + (1.22874 × 10−3 × T^2 × rh) + (8.5282×10−4 × T × rh^2) − (1.99×10−6 × T^2 × rh^2) [1] https://www.weather.gov/media/epz/wxcalc/heatIndex.pdf https://www.weather.gov/media/epz/wxcalc/heatIndex.pdf

    It would be nice if that document cited sources or provided a methodology for how these values were derived.

      Ultimately derived from here: https://journals.ametsoc.org/view/journals/apme/18/7/1520-0450_1979_018_0861_taospi_2_0_co_2.xml?tab_body=pdf https://journals.ametsoc.org/view/journals/apme/18/7/1520-04... The equation came later - the output of that article is just a table, and the equation was derived to be a nice fit over the table's values.

  I came to comment for this very reason. I care a lot about humidity. Ideally you could include both humidity (dew point is the best measure of humidity, btw) and feels like, but just the humidity would be enough. But yeah, as others mentioned, rainfall, storms, cloudiness, etc, are all things that would be great to include.

Has anyone made a map of "unpleasant" day-time hours? I don't need the weather to be ideal - as long as it's not rainy, the high is below 40, and it's a wet bulb with no wind - that works for me.
