Extended Heat Warning notification for the City of Hamilton - July 29, 2019

HAMILTON, ON - The Medical Officer of Health for the City of Hamilton has initiated an Extended Heat Warning beginning on Monday July 29, 2019. The Extended Heat Warning stays in effect until a cancellation notice is sent.

Hot and humid conditions today. Daytime maximum temperatures in the low thirties are expected along with overnight low temperatures near the 20 degree mark. There may be a brief respite from the heat in some areas today as showers or thunderstorms are possible. A cold front is expected to deliver a cooler and less humid air mass to the area on Tuesday.

The City of Hamilton and participating community agencies are responding to the heat by offering “cool places” to go during all stages of a heat event. These locations can be identified by a “Cool Down Here” sign at the entrance.

As part of the heat response plan regularly scheduled Leisure Swims at all City of Hamilton indoor and outdoor pools will be free of charge. There are many spray pads, additional cool places and outdoor pools across Hamilton. For more information visit

The Salvation Army has launched its mobile water distribution response and is distributing water to those in need of hydration.

Signs of heat exhaustion include heavy sweating, weakness, cold, pale and clammy skin, weak pulse, fainting and vomiting. If experiencing symptoms, seek help right away – call 9-1-1 of needed.

Reduce your risk of heat-related illness by following these precautions:

  • Drink plenty of water. Avoid drinking alcoholic and caffeinated beverages on hot days.
  • Go to an air-conditioned place. Visit a cool place such as a mall, public recreation centres, public libraries, and other City run air-conditioned facilities, etc.
  • Dress to protect from the heat. Wear lightweight, loose-fitting, light coloured clothing. Wear a hat or take an umbrella to keep your head cool and don’t forget sunscreen.
  • Take it easy. Limit physical activities (walking, running, gardening, etc.) during the day. If rescheduling activities to dawn or dusk when it may be cooler, protect yourself with insect repellant as mosquitoes are more active at such times. Check labels to apply
  • Cool off. Take a cool bath or shower.
  • Keep your living space cool. Close your blinds or curtains. Open windows to let air circulate when using a fan.
  • Never leave children or pets alone in closed vehicles. Temperatures in a car can become life threatening within minutes.
  • Check on your neighbours and family.
