Vancouver IslandB次元官网网址檚 weather in 2021 could only be termed interesting.

Naturally, December followed suit.

B次元官网网址淭he month started unseasonably mild, but temperatures quickly dropped to about two Celsius below normal which indicates a strong La Nina as originally expected,B次元官网网址� noted Chris Carss, who compiles statistical information for Environment and Climate Change Canada at his Chemainus home.

Temperatures over the past six months have seen one example of extreme weather followed by another, he added. The heat dome in the summer and this winterB次元官网网址檚 very cold temperatures couldnB次元官网网址檛 be more opposite and then there was the July precipitation shutout matched against NovemberB次元官网网址檚 heavy rains from an atmospheric river and flooding.

December was also a seasonally wet month overall, Carss indicated, B次元官网网址渂ut rainfall actually was well below normal because most precipitation was in the form of snow, of which we had about three times our December normal.

B次元官网网址淭he rain and snowfall anomalies cancelled each other out to give us near normal combined precipitation.B次元官网网址�

Other points of interest for December were: dry days with sunshine came out about a day less than normal; and there was a larger discrepancy in overall days with mostly or partly sunny conditions, with or without precipitation, falling below 20 days for the first time since Carss began reporting the statistic.

B次元官网网址淚tB次元官网网址檚 not a value recognized by Environment Canada or the World Meteorological Organization, but a monthly total I now believe is important on the west coast where we get a lot of days with mixed weather which tend to be counted only as wet weather days which can exaggerate our representation for having gloomy weather,B次元官网网址� Carss added.

As for the outlook for remainder of January, Carss foresees a continuation of La Nina conditions with below normal temperatures and above normal precipitation most of the time.

B次元官网网址淒iscrepancies might not be as great as last month, and storms might not be as powerful, but there will likely be some rough days ahead all the same,B次元官网网址� he pointed out.
