Has the climate in Billings changed?

Billings has warmed about 0.9°F since 1971.

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

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 3 fewer freezing nights a year and about 3 more days above 90°F compared with the 1970s.

October has cooled the most — about 2.4°F. The warming runs across the whole year, not just one season.
