A daily rainfall total says little on its own: the same 5 mm can be one short downpour or a grey day of drizzle, which is why the hourly chart above is often the more useful of the two. Over the next fortnight the highest UV index for Warsaw is 5, which is low to moderate.
The first three to five days are generally very accurate. After that the certainty drops off and it is better read as a trend than as an exact daily prediction. Our data comes from Open-Meteo, which combines national weather models — among them the Met Office, DWD and ECMWF — and recomputes them several times a day using measurements from stations worldwide.
