A heat warning is in effect for Peguis First Nation and nearby Fisher River Cree Nation as hot and humid conditions settle over the area this week. Environment Canada issued the warning early Tuesday morning, July 28, 2026, forecasting daytime humidex values reaching 38 degrees Celsius and overnight lows staying in the upper teens for the next several days.
The warning is rated moderate with high forecast confidence, meaning residents should take the heat seriously. Across southern Manitoba, daytime temperatures are expected to climb to 32 degrees Celsius on Tuesday, with the humidex making it feel closer to 40. The hot spell is part of a larger heat wave that has gripped southern Manitoba since early July and already broken temperature records in several communities.
Heat-related illness is preventable, but Environment Canada warns that some people face greater risk. Older adults, infants and young children, pregnant people, and those with chronic health conditions like heart or lung problems need extra care. Anyone working or exercising outdoors, people without housing, and those with limited mobility or confusion are also more vulnerable.
Residents are urged to drink plenty of water, stay out of the sun during peak hours, and check on neighbours who may need help. Signs of heat illness include dizziness, nausea, headache, rapid breathing, and extreme thirst. If symptoms appear, move to a cool place and seek medical help right away. The provincial health information line, Health Links – Info Santé, is available at 204-788-8200 or toll-free at 1-888-315-9257.
Peguis First Nation, Manitoba’s largest First Nation with about 12,706 members, is no stranger to extreme weather. A climate vulnerability assessment has documented the community’s exposure to hotter summers, flooding, and fire risk. The current heat wave underlines the need for ongoing emergency planning as the region faces more frequent severe weather.
