Dauphin, Manitoba is under a heat warning this week as Environment Canada forecasts humidex values climbing to near 40. The warning, issued early Tuesday morning, covers Dauphin and the Rural Municipality of Dauphin including Sifton and Valley River.
Daytime highs are expected to reach 31 degrees Celsius through Wednesday, with the humidex making it feel like 39. Overnight lows will only drop to the upper teens, giving little relief from the heat. Conditions are expected to ease slightly by the weekend, with daytime highs falling to the mid-twenties.
The Environment Canada warning notes the impact level is moderate and forecast confidence is high. Residents are advised to drink plenty of water, check on neighbours who may be vulnerable, and never leave people or pets inside parked vehicles.
This heat arrives while the Dauphin Regional Health Centre, including its emergency department, remains closed due to significant flooding earlier this month. Anyone needing urgent medical care is asked to call 911.
Dauphin is no stranger to summer heat. The normal July high is 25.1 degrees, and the city’s record of 43.3 degrees was set more than a century ago. Still, officials remind the public that extreme heat can be dangerous. The 2021 heat dome across Western Canada contributed to hundreds of deaths in British Columbia and Alberta, while the 1936 heat wave killed at least 780 people in Manitoba and Ontario.
