Has the climate in Coyhaique changed?

Coyhaique has cooled about 0.6°F between 2000 and 2020.

About 0.6°F per decade, measured from Coyhaique's official daily weather records, 2000–2020. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Coyhaique's climate has warmed more slowly than most other cities in Chile.

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 22 more freezing nights a year compared with the 1970s.
