Is BBC Weather accurate?
The UK's most-used weather service, on the BBC website and app.
BBC Weather does not run its own forecast — it blends public models like the Met Office. In our last-30-day test that model scored 88/100 (about ±NaN°C off), but the app never shows you when the models disagree.
How BBC Weather makes its forecast. BBC Weather currently uses a proprietary blend from DTN (formerly MeteoGroup), but is in the process of moving back to the UK Met Office model it used for decades. That matters, because it means the accuracy you get from BBC Weather is really the accuracy of the models underneath it — the same models we test, in the open, against the recorded weather.
Our verdict. Once it completes the switch, BBC Weather will be showing the Met Office model — which scores strongly in our UK test. Today its blend is closed, so the Met Office scoreboard above is the best available guide to its accuracy.

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 300 cities. Lower error means a higher score. The apps you know (AccuWeather, Apple Weather, The Weather Channel) are built on these models.
