Canmore residents and visitors are in for a mixed bag of weather this week, with Environment Canada forecasting cloudy skies, a high chance of showers, and a risk of thunderstorms to start the week. The forecast, issued Monday June 22, 2026, calls for unsettled conditions that could change quickly, a familiar pattern for the Bow Valley.
Monday brings a 60 percent chance of showers and a risk of thunderstorms, with a high of 14°C. Current conditions at 11:00 AM showed 13°C, humidity at 54 percent, and light winds from the north-northeast at 3 km/h, with falling barometric pressure hinting at the instability ahead. Tuesday is expected to be the week’s standout, with sunny skies in the morning and a high of 20°C, though there is a 30 percent chance of afternoon showers and another thunderstorm risk.
From Wednesday through Thursday, the mix of sun and cloud continues with a 30 percent chance of showers. By Friday, conditions begin to deteriorate with a 60 percent chance of showers and a high of 23°C, before temperatures drop to 16°C on Saturday with continuing 60 percent chance of showers. Rain is expected Sunday. For comparison, the average June high in Canmore is 19°C, with lows around 5°C.
This stretch of wet weather comes as lingering snowpack from one of the largest snowpacks on record still blankets high-elevation trails in nearby Banff National Park. Parks Canada issued a hiking hazard warning in May 2026 after several rescues, noting many popular routes remain snow-covered and icy, with freeze-thaw cycles creating unpredictable conditions throughout the day. Hikers heading into the backcountry are urged to check trail reports and carry proper gear.
Mountain weather in the Rockies is known for its rapid changes. Higher elevations can be significantly cooler, windier, and wetter than the valley floor, and afternoon thunderstorms are common in the summer months. Residents planning outdoor activities this week should pack layers and rain gear, and stay alert to updated forecasts.
