Days 1-16 are a real forecast from global weather models. Days 17-30 are season-typical values based on DWD climate normals 1991-2020 — good for planning, NOT an exact forecast that far ahead.

How does the long-range forecast work?
Days 1-16: Fetched live from global weather models (ECMWF, GFS, ICON) with statistical correction. Reliability ~85% for days 1-3, ~60% for days 7-10, ~45% for days 11-16.
Days 17-30: A real forecast does not exist that far ahead (a chaotic system). Instead we show season-typical values: the month’s average Tmax/Tmin from DWD climate normals 1991-2020 directly for Freiburg, with mild weekly variation.
Use: "Roughly how warm is it usually in Berlin in the last week of July?" — a good question for days 17-30. "Will it rain on 27 May?" — no serious forecast can say.
