September is continuing the trend of record-breaking temperatures in Chilliwack and across the Lower Mainland.

“It was the warmest night ever recorded in Chilliwack!” reported Roger Pannett, volunteer weather observer for Environment Canada, referring to overnight Labour Day.

A high all-time minimum of 22.6 degrees Celsius for Sept. 5 made for a steamy night, as it was more than 12 degrees above normal.

The daytime high of 36.4 C for Monday was the record-breaking hottest day of summer 2017, said Pannett.

It was a hazy, hot day with 23 per cent relative humidity.
