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 Frankfurt am Main the average temperature in August is 20,3 °C, in September it's 15,9 °C (1991-2020 climate mean for the local climate station, see below). We show openly how often our forecast actually holds up.
