How reliable is a 14 day forecast?
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.
