Has the climate in Colima changed?

Colima has warmed about 18.2°F between 1989 and 2020.

About 5.9°F per decade, measured from Colima's official daily weather records, 1989–2020. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Colima's climate has warmed faster than most other cities in Mexico.

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 48 more days above 90°F compared with the 1970s.
