How accurate is BBC Weather? ›

In a composite measure of accuracy, the Weather Channel and Weather Underground came top, AccuWeather fifth, MeteoGroup (the BBC's new provider) sixth and the BBC ninth (based on Met Office forecasts). On the correct prediction of precipitation, MeteoGroup came fourth overall and the BBC 10th of the 12.
