About 0.2°F per decade, measured from Raymore'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? Raymore's climate has warmed more slowly than most other cities in United States.
What has actually changed

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.

How much warmer each month is now than in the 1970s.
Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
December has warmed the most — about 2.0°F. The warming runs across the whole year, not just one season.
