Independent accuracy tracking

Powered by ForecastWatch, we've been comparing weather forecasts to actual conditions since 2004. Our data covers billions of forecasts across over 2,200 locations worldwide from major consumer and government weather services.

How accuracy is measured

Temperature accuracy is the percentage of forecasts within 3°F of the actual reading. Precipitation accuracy is the percentage of correct rain and snow forecasts. Scores are computed from one- to three-day-out forecasts, updated daily.
