Toronto - Recent October Temperatures, Rain & Snow





The numbers here describe what the October weather in Toronto, Ontario Canada was like for every year since 2010. A series of tables gives October data by year for temperature, precipitation and snowfall.

They begin with average maximum and minimum temperatures in degrees Fahrenheit and Celsius. That's followed by how many hot or cold days occurred each October. Then there's information on how much rain and snow actually landed this month during recent years, as well as how often Toronto had wet or snowy weather.

The climate data come from weather measurements made in downtown Toronto, except for snowfall which was recorded at Toronto Pearson International Airport.
