How cold is it?

Blog statistician Ray Perrott suggests that Banff may be experiencing the coldest ever February, at least since we’ve been keeping records.

  1. February 1936 might have been colder, or at least it was in the Edmonton area and Environment Canada’s website does not have data for Banff for 1936 so it is hard to say. I would like to show Banff’s temperature trend here, but I can’t post a pdf. The annual extremes are converging with annual highs tightly clustered around 30C, rising about 1C over 130 years, and annual lows, with much more variation, rising 3C over 130 years. The lowest temperature was -51.1C in January 1950, which is the only sub -50C I could locate in the records for Banff. I expected sub -50C to be more common.
