Waterloo Region was feeling the heat last month to kick off summer, with one of the hottest Junes on record.
According to statistics gathered at the University of Waterloo’s E.D. Soulis Weather Station, it was the sixth hottest June on record based on statistics from the last 100 years.
The heat peaked on June 24 when temperatures reached 35 C, the third hottest temperature ever recorded at the weather station, which has been operating since the beginning of the 21st century.
“Temperatures were two to three degrees above average for the month of June, especially during the daytime,” said 570’s Weather Specialist Allister Aalders. “That heat wave we had certainly stands out the most. We had temperatures in the low-to-mid thirties and humidex values into the high thirties and the forties.”
In all, five days in June had recorded temperatures above 30 C, and the average temperature over the month was 2 C higher than normal.
As we move into July, Aalders expects the hot weather to resume, with highs of 32 C expected for Sunday.
Some wet weather is also set to move in, with the chance for thunderstorms on Wednesday night and throughout the weekend.
