With September now in full swing across Waterloo Region, experts are sharing the details on what residents saw throughout the skies last month, in what was one of the wettest Augusts the region has seen in decades.
The E.D. Soulis Memorial Weather Station at the University of Waterloo said that, while the temperature was almost perfectly average, with only a few fluctuations throughout the month, the rain and wet start to August were pretty attention-grabbing.
“The month got off to a very wet start with 47.6 mm coming down on the second day. It was then consistently pretty wet throughout the rest of the month, with a few more very rainy days near the end,” said Frank Seglenieks, Coordinator of the E.D. Soulis Memorial Weather Station.
“Overall, the total for August was 139.7 mm, more than twice the average 66.2 mm. This is the second wettest August in the almost 30-year history of the E.D. Soulis Memorial Weather Station.”
He added that the totals seen throughout the month also contributed further to what has already been a wet 2026 across Waterloo Region, stating that it put the total precipitation so far in 2026 up to 740.7 mm, almost 25 per cent higher than the usual average of 596.0 mm.
“The statistics for the meteorological summer (June-July-August) were that the temperature was just 0.6 degrees above average and the total precipitation of 319.3 mm was well above the average of 221.0 mm.”
All in all, on the temperature side, Seglenieks said that the maximum temperature seen hit 39.2 C, while the coldest hit a low of 8.9 C.
