Average temperature: 18.2C (0.3C below normal) Rainfall: 18.2 mm (56.9 mm below normal) Generally cool and dry (for most).. After a couple of active and stormy summer months, August was generally a quiet month with little in the way of extreme heat or strong storms. The notable exception to this was on August 9th when severe thunderstorms tracked from the Dauphin area to northern Winnipeg bringing damaging hail and heavy rain along its track. The Dauphin area was particularly hard hit with baseball size hail causing damage to almost every vehicle and roof in town. Hail damage is expected to exceed $50 million. Otherwise the month was fairly tame with a noticable lack of heat and humidity, and consequently a lack of strong thundestorms especially over the south part of Winnipeg. Here in Charleswood monthly rainfall was a scant 18 mm, some 57 mm below normal for August. However the north part of Winnipeg was hit with about 75 mm of rain during the month, illustrating how most storms tracked over the north part of the city during August. Winnipeg Airport recorded 28 mm for the month, while the Forks had 39 mm. Temperatures for the month averaged slightly below normal at my site (0.3C below normal) while Winnipeg airport's 17.2C mean was over a degree below normal. The month had several stretches of below normal temperatures with only 2 days able to reach the 30C mark. All in all.. a generally cool and dry (for most) end to summer.
