Has the climate in Poway changed?

Poway has warmed about 2.5°F since 1980.

About 0.6°F per decade, measured from Poway's official daily weather records, 1980–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Poway's warming is broadly in line with other cities in United States — neither unusually fast nor unusually slow.

What has actually changed

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.
