Yesterday I did a post pointing out that most of the really hot temperature records in Canada occurred 1936 to 1941.

Today I noticed that Jeff Masters at Wunderground  was claiming it never got this hot in Fort McMurray before in May.

I’ll just post a few quick facts.

1. The monthly data for Fort McMurray only goes back to 1944. I doubt daily goes further back.
2. The really hot years were the 1936 – 1941 years. So temperature records missed the 1936-1941 period.

Here are the ten warmest May’s (in terms of TX = Tmax) in For McMurray from 1944 on.

1971	5	32.8	-5.6	12.3
