Got tired of forecasts being wrong and having no way to check. So I built an app that overlays what models predicted days ago vs. what actually happened, so you can literally see the accuracy on a timeline.
You can compare all open-meteo models (such as IFS, AIFS, AIGFS...) side by side. Choose how many days back you want to check (it uses open-meteo's Previous Model Runs API) and the app shows the previous prediction as a "ghost line" against observed data. There's also a scoring system that calculates an accuracy by temp, wind, rain and sun hours.
Features:
- Compares previous predictions vs. observed data
- Built-in scoring system that calculates accuracy by temp, wind, rain, and sun hours
- Separate storm accuracy page to choose the best model for predicting storms.
- Free and no ads!
Would love to hear what fellow weather nerds think. Any feedback is welcome!

- ano-ther 5mo agoNice! Even for a non weather nerd like me it makes for a helpful, and privacy friendly, forecast app, especially using the ensemble. The scoring on rain seems a bit binary though. In my area, one got 100%, the rest all scored 0.
- nickoteeno 5mo agoYeah when there's been very little rain, it's just hit or miss ;) Does it still look like that when you increase the Score tab lookback window? I will add some minimum amount of rain though, otherwise the score feels weird indeed
