About 0.4°F per decade, measured from Memmingen's official daily weather records, 1971–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Memmingen's climate has warmed more slowly than most other cities in Germany.

Each bar is one year. Most recent years sit above the older ones.
Some recent years still came in cool — warming is a slope,
not a straight climb.

Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
April has warmed the most — about 1.6°F. The warming runs across the whole year, not just one season.
