St. Paul, Alberta is under a Yellow Air Quality Warning as wildfire smoke continues to drift across the region, bringing reduced visibility and potential health risks through Monday and into Tuesday, according to Environment Canada. A mix of sun and cloud is expected today, but there is a 30 percent chance of showers this afternoon with a risk of thunderstorms, and widespread smoke will persist.
As of 9:00 AM MDT Monday, July 20, 2026, the temperature in St. Paul sat at 17.9 degrees C with north-northwest winds at 12 km/h and 85 percent humidity. Wind is expected to pick up near noon, becoming north at 20 km/h gusting to 40 km/h. The high will reach 24 degrees C, with a humidex of 27. Environment Canada rates the UV index at 7, or high, meaning anyone spending time outside should use sunscreen and wear protective clothing despite the smoky skies.
Air quality and visibility can shift quickly over short distances and from hour to hour, the weather agency warns. Smoke from wildfires in northern Alberta, British Columbia, Saskatchewan, and the southern Northwest Territories is causing moderate impacts across the County of St. Paul. The warning is a joint issuance with Alberta Environment and Protected Areas, Alberta Health, and Alberta Health Services.
Tuesday will see similar conditions with a continued chance of showers and thunderstorms. However, the forecast improves significantly by Wednesday, when sunny skies return and temperatures climb to 29 degrees C. Thursday and Friday will stay sunny with highs reaching 32 degrees C by the end of the week.
Residents are urged to take the thunderstorm risk seriously. According to the province of Alberta, lightning alone kills roughly 10 Canadians each year and causes more fatalities than hail, rain, flooding, wind, tornadoes, and hurricanes combined. When thunder roars, go indoors.
