Alberniweather and Port Alberni Summary for March 2023

Story of March 2023 – The Last La Niña – Amazing Northern Lights

It was a quiet month. We saw fairly average or slightly below average temperatures which is consistent with the 3 years of a La Niña pattern which is now finally ending. The airport only recorded one new short term record this month with a low temperature on the clear night of March 29th.

The clear skies did give us the opportunity for some rare viewing of particularly strong Northern Lights midway through the month. You can see some pictures from across Canada here:

It was notably dry. With City stations receiving not quite half the normal amount of rain and the Airport receiving less than 1/3rd the normal allotment of rain for March.

The snowpack is decent. Jump Creek is at 88% of normal as of April 1st and Wolf River (Strathcona) is 73%.

New Additions – Community Personal Weather Stations

I’ve added two new (and one returning) source of data for the monthly “City Station Values”. You’ll now see values for “Dave’s” station in Uptown Port, “Nick’s” Station from South Port (he’s provided his data to these reports in the past), and a “Kitsuksis” station for North Port. I am able to get the data for all of these stations from their Weather Underground reporting page so I am glad to be able to add them here. We’ll again be able to see the different micro-climate around the City. I may add more at a later date.

That’s all for now! Enjoy the data and graphs below!
