Alberniweather and Port Alberni Summary for January 2023


Story of January – A little boring.

Compared with the entire fall and December, January honestly seemed pretty boring in comparison. We were slightly above average for temperatures and below average for rainfall but not into the extremes. The Airport only marked one new record in its data with the strong rain total mid-month. Other than that, it was fairly quiet. This month’s graphs are after the annual summary.

La Niña’s influence will wane.

We remained firmly under the influence of La Niña conditions in January, however, after nearly 3 years the tide appears to be switching in a big way.

The January 12 Discussion states: (ENSO Discussion – NOAA Climate Prediction Center). “A transition from La Niña to ENSO-neutral is anticipated during the February-April 2023 season. By Northern Hemisphere spring (March-May 2023), the chance for ENSO-neutral is 82%.

We’ll see if there are any indications of an El Niño before summer. It’s too soon to tell now.

Arctic and Antarctic Sea Ice Low

It’s also worth noting that the National Snow and Ice Data Centre has been reporting that both the Northern and Southern ocean ice sheets are near unprecedented low levels. Here is an excerpt from their January 5 report:

Daily extent of Arctic sea ice for December 2022 remained well below average for the entire month; at the end of the month, extent stood at fourth lowest in the satellite record. The average extent for the month ended up as seventh lowest in the satellite record. Antarctic extent is declining much faster than average as austral summer takes hold and is setting record low daily ice extents for the satellite era as of December 22. As such, global sea ice extent is well below average.

One can expect the jet stream to act in strange ways when sea ice is low in the Arctic. I wonder if the low ice in the Antarctic region contributed to the deadly extreme rainfall event in Auckland at the end of January. It seems quite plausible.

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