Which forecast is most accurate in the US?
CheckWeather Score — graded against the weather that actually happened
The CheckWeather Score blends temperature, wind and rain accuracy — each measured against ERA5 (the recorded weather) over the last 30 days across 40 cities. Lower error means a higher score. The apps you know (AccuWeather, Apple Weather, The Weather Channel) are built on these models.
