I checked old 1941-1970 climate normals for places in Alberta and compared
them to 1981-2010 ...yes, big warm up.
Here are 3 examples...3 largest cities in Alberta ...in fahrenheit (hopefully everyone here is bilingual
)
Back before 1975 Canada was a fahrenheit country just like the USA,
the US intended to switch to metric but then decided not to.
Calgary 1941-1970.......Calgary 1981-2010
22.5/2.0........jan.........30.4/8.2
29.1/8.0........feb.........33.3/11.5
34.3/14.3......mar.........39.9/18.5
49.2/26.8......apr..........52.2/28.4
60.6/37.0......may.........61.3/37.6
66.9/44.4......jun..........67.6/45.5
74.3/49.1......jul...........73.8/49.6
72.0/46.8......aug..........73.0/47.8
63.4/39.0......sep..........64.0/39.4
54.0/30.2......oct ..........53.1/29.5
37.7/16.9......nov..........38.1/17.2
28.9/7.9........dec..........30.6/9.0
Mostly a winter “warm up”, which in a colder climate like Calgary is a good thing.
Edmonton 1941-1970.....Edmonton 1981-2010
13.8/-2.9.......jan.........21.2/5.4
22.0/4.1........feb.........27.1/9.5

68.8/48.0......jun..........69.8/49.8
74.1/52.7......jul...........73.6/54.1
71.1/50.1......aug.........72.7/52.3
62.1/41.0......sep..........62.8/42.4
52.0/31.6......oct..........50.7/31.6
32.1/16.9......nov..........32.0/17.2
20.5/5.0........dec..........23.9/8.4
Edmonton also benefitting from a little global warming too, mainly winter.
And Alberta’s banana belt city ....Lethbridge....where 20c in january is not unusual.
Lethbridge 1941-1970.....Lethbridge 1981-2010
25.2/4.8..........jan..........32.2/10.2
32.4/11.6........feb..........36.1/12.9
38.0/17.1........mar.........43.5/20.3
52.9/29.9........apr..........55.6/30.0
63.6/39.6........may.........64.9/39.0
70.2/47.5........jun..........71.6/46.9
79.6/52.1........jul...........79.0/50.5
77.3/50.0........aug.........78.8/49.1
67.3/42.2........sep..........68.4/40.8
57.4/33.9........oct...........56.7/30.9
41.7/20.5........nov..........40.6/19.0
32.2/12.0........dec..........33.1/11.5
Again mainly winter getting warmer, spring too, but fall getting a bit cooler, which is strange.
