European came out on top this month, but read that carefully: the gap between the models is small, and no forecast wins every day. That is the real lesson. Instead of asking "which app is most accurate," the smarter move is to watch all the models at once: when they agree, trust the forecast; when they split, expect surprises. That is exactly what the live UK comparison shows you, town by town.
Common questions
Which weather forecast is most accurate in the UK?
Over the last 30 days, European had the lowest average error, about 0.8°C off the daily high measured across 24 UK cities. No model wins every single day though, which is why we show all three side by side and flag when they disagree.
What is the most accurate weather app in the UK?
Weather apps do not create their own forecast: they display these underlying models. So the "most accurate app" is really the one showing whichever model verifies best where you are, and that changes week to week. Comparing the models directly, as we do here, beats trusting a single app.
How do you measure which forecast is most accurate?
For each model we take its past forecast of the daily high temperature and compare it to ERA5, a reanalysis of what actually happened, over the last 30 days across 24 UK cities. We then calculate the mean absolute error. Lower is better.
How accurate is the Met Office?
In our last-30-day test across 24 UK cities, the Met Office model was a close second, with an average error of about 0.8°C. It is a genuinely strong national model, though ECMWF (the European model) runs it very close.
How accurate is BBC Weather?
BBC Weather uses a proprietary blend from DTN (formerly MeteoGroup) and is in the process of moving back to the Met Office model. Because it is closed we cannot grade its exact numbers, but the Met Office model it is returning to scored 0.8°C in our test above.
