Environment Canada is forecasting widespread smoke and a risk of afternoon thunderstorms for Innisfail, Alberta, starting Monday, July 20, 2026. The smoky conditions are expected to linger through Tuesday, with temperatures climbing throughout the week to well above the seasonal normal.
On Monday morning, light rain was falling at the Red Deer Regional Airport, the closest weather station to Innisfail. The temperature sat at 14.5°C with humidity at 91%, reducing visibility to six kilometres. Despite the damp start, the forecast calls for a high of 21°C later in the day, with a humidex of 26 and a risk of thunderstorms in the afternoon. Wind gusts could reach 40 km/h, and smoke is expected to blanket the area.
Tuesday will bring similar conditions, with a high of 22°C, humidex of 27, and another chance of afternoon thunderstorms alongside the lingering smoke. After that, the skies are expected to clear, and temperatures will rise steadily. By Wednesday, the town should see sunny skies and a high of 28°C, climbing to 31°C on Thursday, which is well above the usual late-July high of 23°C. The heat will ease slightly heading into the weekend, with highs of 27°C on Friday and 23°C by Sunday.
Environment Canada notes that the smoke comes from wildfires burning in northeastern and southeastern British Columbia, northern Alberta, northern Saskatchewan, and the southern Northwest Territories. Alberta’s 2026 wildfire season is projected to be above average, and the area burned by wildfires in the province has nearly tripled over the past few decades.
Health experts warn that there is no safe level of exposure to wildfire smoke. Those with heart or lung conditions, seniors, babies, and pregnant people are especially vulnerable. Symptoms from poor air quality can include headaches, coughing, eye irritation, and wheezing. In serious cases, smoke exposure can trigger heart attacks, strokes, or early death. Residents are urged to stay indoors when smoke is thick, keep windows closed, and use high-efficiency air filters if possible.
During thunderstorms, safety officials remind everyone to go indoors when thunder roars. Lightning kills about 10 Canadians every year, and severe winds and heavy rain cause the most damage across the province.
