Edmonton is on track to break a 112-year rainfall record as the city faces an orange severe weather alert for this weekend.
With 203 millimetres of rain already recorded in June 2026, Edmonton is approaching the all-time June record of 216.5 millimetres set in 1914. Environment Canada has issued an orange alert — described as "likely to cause significant damage, disruption, or health impacts" — for another wave of heavy rain expected between Saturday and Sunday.
Matt Loney, a meteorologist with Environment Canada, said the coming deluge could push Edmonton into striking distance of its all-time single-month record: 282 millimetres, recorded in July 1901. "I would say reaching the second most rain ever in a month is a strong bet, and I think with the amount of rain we could get this weekend, we will get into striking distance of the July 1901 record," he said. "If we get some embedded thunderstorms, it could increase the chances that we break the all-time record."
The ground in the Edmonton region is already saturated, creating significant risk for overland flooding, washouts, and impacts to infrastructure and property. Heavy rain last weekend forced temporary closures at golf courses and prompted hundreds of sports leagues to postpone or cancel games.
Loney noted that the pattern could persist into early July, with more upper-level low-pressure systems expected to bring additional thunderstorms and showers. "Once this storm leaves Sunday, we may see a nice day on Monday, and then another upper trough is going to descend," he said.
