October 2022 – October Heat Leads to Raft of Records and Shocking Averages

Records were set!

Alberniweather and Port Alberni Summary for October 2022

Story of the Month – Summer that never ends!

The story was the heat with a side of extended drought. The normal average temperature for the month of October is the same whether you’re talking about the Airport (Valley) or town (closer to the sea). Both the City stations and the Airport had average maximum temperatures 5.9º C hotter than normal. Shocking.

In other words, your normal high temperature during October would average out around 14-15ºC. This October, the average was over 20ºC. It was the highest in the records dating back to 1900. 1906 was the top before, and frankly it looked like an outlier. This month, even though the Airport was missing data from the 6th, one of the hottest days, it still tied that record and so will have been hotter. Alberniweather was 1ºC hotter still.

The Airport set a new standard in its own records (since 1994) on 19 or 31 days. 17 of those more than half of the month, new highs. Stunning.

5 new all time day highs were set going back to 1900 though the top for the month, 31.7ºC, was not.

We also had no rain for the majority of the month. Continuing a dry spell that began in late July. We ended up getting a few days of rain which brought us up to around 1/3rd of our normal rainfall for the month.

Check out the list of records below and the graphs that show a couple more.

Daily and All Time Day Records Set

Set at Airport* since 1994 and compared to other stations** since 1900 (1895 for rain)

Nineteen of thirty one days set some sort of record at the Airport since 1994. The Airport now holds one new All Time Record high temperature for October 15 and is 2nd only to Robertson Creek which now holds All Time Records for October 2, 3, 14 and 16. In addition the Airport set a low temperature and rainfall record on October 23 and 27 respectively. They were not all-time records.
