Has the climate in Pendleton changed?

Pendleton has warmed about 1.9°F between 1971 and 2023.

About 0.4°F per decade, measured from Pendleton's official daily weather records, 1971–2023. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Pendleton'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 12 fewer freezing nights a year compared with the 1970s.

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.
