Has the climate in Red Deer changed?

Red Deer has cooled about 0.7°F between 1971 and 2014.

About 0.2°F per decade, measured from Red Deer's official daily weather records, 1971–2014. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Red Deer's climate has warmed more slowly than most other cities in Canada.

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

January has warmed the most — about 2.5°F. The warming runs across the whole year, not just one season.

Methodology & sources

Temperature — 1991–2020 normals computed from 23 years of daily observations at Red Deer A, a weather station, about 11 km from the city centre. The underlying daily records come from NOAA's global station network.
