The line at the top answers that for where you are, minute by minute: "No rain in the next hour", "Rain in about 20 minutes", or "Raining now, stopping in 10". It's worked out from Apple's minute-by-minute forecast and checked against the Met Office rain radar, which we read every 15 minutes.
The bars show the chance of rain for each hour left today. We call an hour likely to rain at 50% or more. A 40% hour is a genuine maybe; what a chance of rain means explains what to do with one.
The last line gives tomorrow's chance of rain and how warm it gets. A forecast for tomorrow is nearly as good as one for the next few hours: in our marking, rain calls for the next day came true 56% of the time and dry calls about 19 hours in 20. Beyond three days, treat a rain icon as a maybe. The numbers are in how far ahead the forecast is accurate.
It blends five forecasts (the Met Office, Apple, YR, DWD and Tomorrow.io) and leans on whichever has been right lately, then checks the next hour against live radar and real rain gauges. Every forecast is marked in public against what actually happened on the accuracy page, including the ones it gets wrong.
Five forecasts blended into one plain answer, with every one of them marked in public against what actually happened. Free, no account, no ads.
