I live near Nanaimo BC (data from 1947 at “NANAIMO A”). I was curious what the temperature range for any given day would be.
By temperature range I mean find the warmest it has ever been for a particular day and then subtract the coldest it has ever been.
December 1st , February 4th, November 14th and May 16 have the biggest range = 32.8C.
November 18th has the lowest range = 16.9C. (I find it interesting it has never been colder than -4.4C on November 18 when it has been -16.1C on November 14th.
(Remember this when someone says humans and animals will notice a 1C change in the next 100 years).
Top 10 and bottom 10 below.
