Taking a dip in Toronto's pools is a great way to stay cool and be safe during the hot summer months in the city. When an Extended Heat Warning is declared, and when the weather forecast calls for low probability of inclement weather such as heavy rain or lightning, some outdoor and indoor pools may extend their hours until 11:45 pm.
When the extended hour program is in effect at our pools, the Parks, Forestry & Recreation homepage will be updated in the early afternoon on the day of the extended opening. Parks, Forestry & Recreation will also notify Toronto media to help alert the public.

What is a Heat Warning?
From May 15 to September 30 of each year, Toronto Public Health staff monitors the Harmonized Heat Warning and Information System to determine when the Medical Officer of Health should declare a Heat or Extended Heat Warning. Using spatial synoptic classification, this system compares forecast data to historical meteorological conditions which have in the past, lead to increased mortality in Toronto.
Forecast data includes weather conditions such as temperature, dew point, humidity, cloud cover, wind speed and direction. The system also considers when in the summer season offensive conditions are present and the number of consecutive days oppressive conditions occurred.
A Heat Warning is issued when an oppressive air mass is forecast and the likelihood of excess weather-related mortality exceeds 65% and an Extended Heat Warning when the likelihood of excess weather related mortality exceeds 90%.
