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.

Long-range forecast · Regensburg
Regensburg — 30-day analysis
Across the 30-day trend for Regensburg, highs and lows span 10° to 36°, cooling down later in the month. The first 16 days are a real forecast, with rain on about 9 of them; the rest is based on the 1991–2020 climate normals.
How does the long-range forecast work?
Days 1-16 are a real forecast from global models (ICON, ECMWF, GFS): days 1-3 are almost always right, uncertainty grows afterwards, and from day 11 these are tendencies rather than exact values.
From day 17 a serious day-by-day forecast is physically impossible. We therefore show the 1991-2020 climate normals (monthly mean Tmax/Tmin) directly for Regensburg, with mild weekly variation — the typical weather for the season, not a daily prediction.
Rule of thumb: good for “how warm is it usually in late July?”, not for “will it rain on the 27th?”.
