Waterloo Region is finally getting some relief from the oppressive heat, and looking back on one of the hottest months in the last three decades.
According to 570’s Weather Specialist Allister Aalders, the temperatures surpassed the 30 C mark 10 times throughout July, well above the 30-year average of four days per July. Additionally, last year in July only provided two days where the thermometer climbed above 30 C.
“The atmospheric pattern favoured a hot, humid air mass to continuously move into southern Ontario,” said Aalders.
“We had these large areas of high pressure parked well to our south and southeast, and that pumps in a very warm and humid south and southwesterly flow. When you get that moving around a ridge of high pressure, not a lot of rain moving through, you get this very hot, dry, and humid pattern.”
The temperatures peaked on Monday when the thermometer reached a high of 33.1 C.
“Looks like, on average, we were around two degrees warmer this July, the warmest anomalies being our daytime highs, where they were around two degrees warmer than average,” he said.
According to Aalders, the stretch of warm weather isn’t done yet, as the long weekend provides a high of 29 C on Monday.
August is set to kick off with some humid weather, but with temperatures below the averages recorded throughout July.
