About 1.2°F per decade, measured from Konstanz's official daily weather records, 1972–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Konstanz's climate has warmed faster than most other cities in Germany.
What has actually changed
Each card compares the 1970s (the first ten years of the

Average temperature for each year from 1972 to 2025.
a warmer-than-average year a cooler-than-average year
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.
In day-to-day terms, that long-term shift shows up as about 5 more days above 90°F compared with the 1970s.

Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
April has warmed the most — about 2.8°F. The warming runs across the whole year, not just one season.
