Ottawa - Recent April Temperatures, Rain & Snow





The numbers here describe what the April weather in Ottawa, Ontario Canada was like for every year since 2010. A series of tables gives April 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 April. Then there's information on how much rain and snow actually landed this month during recent years, as well as how often Ottawa had wet or snowy weather.

The climate data come from weather measurements made near downtown Ottawa, except for snowfall which since 2020 was recorded at Ottawa International Airport.
