Chestermere, Alberta is under a heat warning as Environment Canada expects temperatures to climb well above seasonal norms this week, with Saturday possibly hitting 37 degrees Celsius. The warning was issued early Tuesday morning and covers Chestermere along with nearby areas in Rocky View County like Dalroy and Dalemead.
Daytime highs are forecast to hover between 30 and 34 degrees through the week, far above the late July average of 26 degrees. The hottest day is expected Saturday, August 1, when the mercury could reach 37. With overnight lows mostly in the low to mid-teens — and dipping as low as 11°C on Thursday night — there will be only limited relief from the heat, raising the risk of heat-related illnesses.
According to Environment Canada, heat warnings are issued when conditions pose an elevated risk of illnesses like heat stroke or heat exhaustion. The agency says the body needs cooler nights to recover, and prolonged heat without that break can be dangerous. Residents are urged to stay hydrated, avoid strenuous activity during the hottest part of the day, and never leave children or pets in a parked vehicle.
Alberta Health Services says some people are at greater risk, including older adults, infants, pregnant women, and those with existing health conditions or no access to air conditioning. They recommend checking in on neighbours who live alone or may be vulnerable. Anyone needing health advice can call Health Link at 811.
The heat warning comes with a UV index of 8, which is considered very high, so sun protection is important. A fog advisory for the area earlier Tuesday morning has since lifted. The City of Chestermere and surrounding Rocky View County will be watching conditions as the week continues.
