So how do we tell if they’re right?
Well, rather than scurry around the whole of the UK in order to check their weather divinations, I’ve chosen to take the easy route and use the BBC’s own web pages. The five day weather predictions also include today’s weather. I’m making the assumption that predicting today’s weather is dead simple, so the BBC couldn’t possibly get this wrong. So every day, a computer script reads the latest five day forecast, and compares today’s weather with what the BBC said it would be in their previous forecasts.
Over time, as this program collects more and more of the weather predictions, we’ll be able to see how often the weather forecasts were right.
What are the results?
The tables below show the accuracy of the BBC’s weather forecasts, listed by time. E.g. as I write this, the table below shows that the weather forecast for Cambridge one day ahead was 53% accurate. In other words, the BBC’s guess about tomorrow’s weather in Cambridge was right roughly half of the time.
