Environment and Climate Change Canada has issued a Heat Warning for London and Middlesex County starting today, Monday, August 26th, and continuing through Tuesday evening, August 27th. The heat is expected to subside on Wednesday, August 28th, with temperatures forecasted to drop to 28°C, bringing the heat warning to an end.

Heat Warnings are issued when one or more of the following criteria are met:

• Environment and Climate Change Canada issues a forecast calling for a daytime high of 31°C or higher and a forecast low of 20°C or higher for two consecutive days, or;
• Environment and Climate Change Canada issues a forecast calling for a Humidex of 40 or higher for two consecutive days, or;
• Environment and Climate Change Canada Forecasters anticipate that actual temperatures and humidex values in London and Middlesex County will reach the thresholds noted above.

Higher temperatures can also impact air quality, which can then increase the risk associated with the heat. At this time, the forecasted Air Quality Health Index level for London and Middlesex County during this Heat Warning is to reach a maximum of 5, or Moderate Risk.

The Middlesex-London Health Unit is reminding the public to take steps to stay cool and to keep hydrated during this heatwave and recommends the following tips to avoid the risks of heat-related illness:

• Drink plenty of water throughout the day, even if you don't feel very thirsty.
• Never leave a child or pet in a parked car or sleeping outside in direct sunlight.
• Avoid drinking caffeinated or alcoholic beverages, including coffee and cola.
• When possible, avoid spending too much time outdoors.
• Keep shades or drapes drawn and blinds closed on the sunny side of your home.
• Take a cool bath or shower periodically or cool down with cool, wet towels.
• Avoid intense or moderately intense physical activity, particularly outside.
• Use fans to draw cool air at night, but do not rely on a fan as a primary cooling device during extended periods of excessive heat.
• Reduce the use of personal vehicles and unnecessary idling.

How Can Landlords Help Prevent Heat Illness in Tenants?

• Provide residents access to a cooler spot for several hours at a time, e.g. a common room with air conditioning or a basement area.
• Check on your neighbours who are vulnerable to ensure they have access to a cooling centre or space.
• Provide heat safety information to residents or post the information in common areas (e.g. by the elevator, in the lobby, etc.).
