Common questions

How reliable is the forecast for Basel?

How often is the weather for Basel updated?
The weather services run their models several times a day. This page refetches the forecast at least hourly, the cockpit every time it opens.
Where does the weather data for Basel come from?
From the national weather services’ models via Open-Meteo. Official warnings for Switzerland come from MeteoAlarm — in the wording of the source, not in ours.
