It wasn’t until about a week into December that Fredericton finally got snow that lasted. While surprising for a city that usually by this time of year has walls of snow start to form, this isn’t quite off par with recent weather patterns.
Historically, Fredericton has seen a rise in seasonal temperatures for the holiday season. Additionally, snow at the start of the month is fairly rare in general for the city.
Government of Canada public charts show that Fredericton has never seen any substantial snowfall until about the midway point in the month, and recent projections prove the same for 2020, with flurries picking up near the middle of our third week.
2010 was in fact the most unseasonal year, with heavier-than-usual snowfall, though it immediately melted due to rain.
Heavy snowfall typically doesn’t begin (and last) until closer to the new year. An average of 10 to 15cm a day, with temperatures dropping to -10 celcius in the usual forecast as per historical data.
Temperature fluctuations have always been present as well, drastically swinging back and forth from highs around 10 to lows around -15. For example, December 9th, 2000 had a high of -13, but then a high of 15 on the 17th.
Nor is it usually a white Christmas. Even the year 2010 showed minimal snow on the ground from Christmas Eve throughout Boxing Day, and several other years surrounding it showed none at all.
