In August, the rains decrease considerably. Precipitation is fairly low at 50.8mm (2") averagely, from twelve days of rainfall. As much as more crowds are experienced in Toronto, the sunshine hours drop to nine per day as the humidity rises even further.
While some days may experience extremely high temperature, most days remain in the range of 17°C (62.6°F) and 24°C (75.2°F). The majority of the nights are cool and tolerable appreciative of the afternoon showers of rain.
Schools are closed for the summer, and the crowds become even larger. As a result, prices are hiked on almost everything, and it is wise to make any summer bookings earlier.
