Has the climate in Saint-Georges changed?

Saint-Georges has warmed about 2.1°F between 1971 and 2020.

About 0.4°F per decade, measured from Saint-Georges's official daily weather records, 1971–2020. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Saint-Georges's warming is broadly in line with other cities in Canada — 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.

Temperature — 1991–2020 normals computed from 30 years of daily observations at ST Georges, a weather station, about 5 km from the city centre. The underlying daily records come from NOAA's global station network.
