About 0.0°F per decade, measured from Guiyang's official daily weather records, 1971–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Guiyang's climate has warmed more slowly than most other cities in China.

Wetter on average
Guiyang's temperature, year by year
Average temperature for each year from 1971 to 2024.
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.
When in the year the change shows up
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.
January has cooled the most — about 2.0°F. The warming runs across the whole year, not just one season.
