Environment Canada says an unseasonable cool air mass over southern B.C. has broken minimum temperature records, including one dating back about 70 years.

The forecaster says temperatures fell to 4 degrees in the Trail area on Sunday, breaking the record of 4.4 C set in 1954.

In the Bella Bella area, the minimum of 3.9 degrees broke the 4-degree record set 10 years ago.

Records for low daily maximum temperatures were also set, with the Kelowna area reaching just 13.3 Celsius, breaking the 15-degree record set in 1906.

Penticton and Princeton also reset records established in 1939, while other low daily maximum records were set in Summerland, Sparwood, Nakusp, and Kamloops – where the temperature was 15.1 C, down from the old record of 15.4 C set in 1991.

A new record was also set in Merritt as the temperature hit a high of 11.5 C Sunday, breaking the old record of 13 C set in 2014.

Lytton was also a record breaker, getting to just 15.2 C, a far cry from the all-time Canadian heat record of 49.6 C set on June 29, 2021, just a day before a wildfire killed two people and destroyed much of the village.
