Has the climate in Grimsby changed?

Grimsby has warmed about 5.1°F between 1993 and 2013.

About 2.4°F per decade, measured from Grimsby's official daily weather records, 1993–2013. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Grimsby's climate has warmed faster than most other cities in Canada.

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.

Methodology & sources

Temperature — 1991–2020 normals computed from 20 years of daily observations at Vineland, a weather station, about 13 km from the city centre. The underlying daily records come from NOAA's global station network.
