Nanaimo BC Temperature Range

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.

  1. I live just down the road…we get all that plus the power blows out when the storms roll through.

    (We should go for a beer one of these days. Contact info is on my site.)

    1. Beer!? Do you know how much catastrophic CO2 gets released into the atmosphere by simply pouring a beer?

      As for those extreme temperatures in mid-November, it looks like that’s from an extreme cold snap that absolutely shattered any previous record. By the end of the month, the temperature had warmed to something more reasonable, hence the more reasonable extreme lows. 1955 was the coldest year on record in Nanaimo for both the mean and maximum temperatures. Even when I use the other Nanaimo station that goes back to 1893, 1955 is the coldest year, which is CLOSER TO TODAY THAN IT IS TO 1893. Put that in your global warming pipe and smoke it.
