Edmonton and northern Alberta are experiencing a sharp rise in temperatures this week, prompting Environment Canada to issue heat warnings across large portions of the province. After a relatively stable June and July, where temperatures hovered around seasonal norms, the sudden arrival of intense summer heat has raised concerns about public safety and well-being.

According to weather specialist Phil Darlington, Edmonton has only recorded a few days above 30°C this summer. However, the current forecast shows daytime highs near or above 30°C with overnight lows between 14°C and 18°C. Warm temperatures began rising on Wednesday and will likely continue for a few more days before tapering off by the weekend.

Environment Canada attributes this spike to an upper ridge moving into Alberta, causing both temperatures and humidity levels to climb. While 28°C was recorded mid-day Wednesday, humidity made it feel closer to 32°C — a humidex effect that makes the heat feel more intense.

High humidity can impair the body’s ability to cool down through sweat evaporation. When the air’s moisture content is high, sweating becomes less effective, potentially leading to conditions such as heat exhaustion or even heat stroke.

In response, the City of Edmonton has activated its extreme heat strategy. Measures include 24/7 potable water stations at various fire hydrants, distribution of bottled water by peace officers, and allowing public access to facilities such as libraries and recreation centres for shelter and hydration. These facilities also offer bottled water and N95 masks.

Officials urge residents to stay hydrated, avoid strenuous outdoor activity during peak heat, and check on vulnerable populations. Warning signs of heat-related illness include nausea, dizziness, confusion, and in severe cases, loss of consciousness.

The heat warning currently affects all regions north of Red Deer and parts of eastern Alberta, including Drumheller and Brooks. It remains in place through Saturday morning but may be extended depending on conditions.

Residents are encouraged to contact 211 for non-emergency support or 911 in urgent situations involving heat distress.
