The fall in Ottawa will either be rainy with normal temperatures or warmer than normal with below-average precipitation, but all forecasts are predicting El Nino will push winter’s arrival to the side. Environment Canada and the Weather Network have released their fall forecasts for Ottawa and across Canada. It will be a rainy fall with normal temperatures in Ottawa, according to Environment Canada. Environment Canada’s three-month forecast calls for normal temperatures through September, October and November. Ottawa is expected to see above-normal precipitation levels over the next three months, the weather agency said. Meteorologist David Phillips says El Nino will impact the weather later this fall and into the winter. “This is the Godzilla of El Nino’s,” Phillips told Newstalk 580 CFRA’s The Morning Rush with Bill Carroll. “We won’t see in 80 years a stronger El Nino than this one.” Phillips looked back to the last El Nino in 2023-24 in Ottawa, with temperatures averaging 3 degrees warmer than normal and no skating on the Rideau Canal Skateway. “The odds clearly favour…it’s almost not cancelling winter, but it’s a very soft, open kind of winter. Winter is just not there for people that love winter,” Phillips said. The summer in Ottawa was the wettest summer in Ottawa’s history. Ottawa received more than 535 millimetres of rain through June, July and August. Weather Network The Weather Network’s fall forecast, released on Wednesday, calls for above-seasonal temperatures in Ottawa and eastern Ontario this fall, with below-normal precipitation levels. “A large chunk of mid-September through mid-October may actually run surprisingly close to seasonal,” the Weather Network said about fall in Ontario. “A delayed arrival of sustained cold creates concern for early ski-area snowmaking. A larger warmth signal emerges by late fall.” The Weather Network says “fewer classic fall storms” are expected in Ontario. In its fall forecast, the Weather Network says a potentially historic El Nino could prolong the fall season and delay the arrival of winter. “El Nino will cast a long shadow across Ontario’s fall this year,” the Weather Network said.” “The province will experience above-seasonal temperatures in the coming months.”
