Extreme Heat and Humidity

Please see below an update from Ottawa Public Health (OPH):

When the temperature and humidity are high, our bodies can overheat, especially in the first few days of hot weather while our bodies adjust.  

Hot and humid air can also bring deteriorating air quality and can result in the Air Quality Health Index approaching the high-risk category. It is recommended that you Download the WeatherCAN app to your mobile device to stay informed of all weather alerts. 

Extreme heat affects everyone. The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors. Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions. Heat-related illnesses and deaths are preventable.  

There are many public places residents and visitors can cool off in Ottawa including splash pads, wading pools, swimming pools, parks, libraries, and community buildings. The public is welcome to seek access to air conditioning at any City facility during regular hours of operation.
