A heat warning is in effect for Steinbach and the surrounding R.M. of Hanover area, including Niverville and Grunthal, as temperatures climb into the low 30s with humidex values expected to reach 38 through the coming days.
Environment Canada issued the warning at 4:23 a.m. on Tuesday, July 28, 2026. Daytime highs of 32 degrees Celsius and warm overnight lows in the upper teens will offer little relief from the heat, increasing the risk of heat-related illness.
The hot, humid conditions are part of a stretch of extreme weather expected to last through the week, potentially into Sunday, August 2. Officials warn that everyone is at risk, but the health impacts can be especially serious for older adults, infants and young children, pregnant people, and those with chronic conditions such as heart or lung problems or high blood pressure. People who work or exercise outdoors, those without access to air conditioning, and anyone experiencing homelessness or confusion are also considered more vulnerable.
Anyone who does not have air conditioning at home is encouraged to spend time in cool public spaces such as cooling centres, community centres, libraries, or shaded parks. Manitoba Health also has heat advisories in place, and residents can call Health Links at 204-788-8200 or toll-free 1-888-315-9257 for health-related questions.
Heat stroke is a medical emergency, and Environment Canada urges people to watch for red, hot skin, dizziness, nausea, confusion, or changes in consciousness. Anyone showing these signs should be taken seriously, and 9-1-1 should be called immediately.
The warning follows a summer of record-breaking heat across southern Manitoba, with 24 communities setting temperature records earlier this year. In Steinbach, the mercury reached 34.4 degrees Celsius in mid-July, tying a record from 1969, according to historical data.
