August was hot and dry

This past August was hotter and drier than average, despite the humidity. 

The mean temperature for August 2021 was 22.3 C and while we had several days with high humidex values, the moist air didn't translate into precipitation. Just 49 mm of rain fell at the Ottawa Airport, according to Environment Canada.

Between 2012 and 2020, the average mean temperature for August was 20.1 C and the average rainfall was 92.1 mm.

August 2021 was marked with several high humidity days and heat warnings in effect for numerous days in a row. There were 11 days in August this year with high temperatures at or above 30 C and four days with lows higher than 20 C.
