Outlook: the next few weeks

A genuine day-by-day forecast only reaches about 10 days out – anything beyond that is statistics, not a forecast. That's why we don't show a 30- or 90-day outlook. What can be honestly stated is the long-term normal: in Darmstadt the average temperature in September is 14,8 °C, in October it's 10,2 °C (1991-2020 climate mean for the local climate station, see below). We show openly how often our forecast actually holds up.

How reliable is the forecast?

How our forecast daily high has shifted across recent runs. Flat line = the forecast is holding, jittery = still shifting.
