The record for the rainiest month was broken on July 30 when Pearson International Airport recorded 7.4 mm (0.29 inches) of rainfall, bringing the monthly total to 215.4 mm (8.48 inches) due to slow-moving scattered storms that swept through the region.
The previous record was set in October 1954 when 213.8 mm (8.41 inches) of rainfall was recorded due to the impact of Hurricane Hazel.
Toronto’s third rainiest month is now September 1986 which saw 212.2 mm (8.35 inches) and the fourth is May 1942 with 208.6 mm (8.21 inches).
