September is underway, but experts say the start of Canada’s fall season – especially in the eastern regions – could feel like summer.
According to Anthony Farnell, chief meteorologist at Granthshala News, warm weather temperatures range between 5C and 8C above normal and could stop well into October.
Farnell said temperatures in major cities such as Toronto, Ottawa, Montreal and Halifax remain close to 20C, and they are expected to climb into the mid and upper twenties by the end of the month.
“When you have a high level of about 28 degrees in late September in Toronto, it becomes unusual,” he said.
However, in western provinces such as British Columbia, the temperature has changed more.
BC has seen unprecedented and severe heatwaves over the past few months that have broken records and claimed hundreds of lives.
Alberta also suffered a heatwave this summer as record temperatures reached 30C or higher and smoky air quality persisted for nearly three weeks into August.
“We now have cooler conditions in BC and Alberta,” Farnell said.
Temperatures have been recently, on average, BC and in Alberta sits at around 15C and 18C.
“(But there’s) all kinds of heat and even humidity that’s also likely to stay in October over the Great Lakes, Quebec and areas around Atlantic Canada,” he said.
It is a tough call to determine whether climate change is behind the latest round of rising temperatures.
On the one hand, scientists say there is a “clear link” between climate change and extreme weather.
in August, Intergovernmental Panel on Climate Change released a report Which warned the entire world – and with it, Canada – was on track for more devastating wildfires, smoldering heat waves and other extreme weather events if climate change was not reversed.
But Farnell said the East Coast has naturally warmer waters, with parts of Canada including Ontario, Quebec and the Atlantic having warmer September cycles for the past 15 years.
“It is almost as if the weather has changed a bit where we are now getting good weather in September and early October and then more clouds, rain and cooler conditions in April and early May,” he said, Given that Canada may also be in for an earlier winter.
Gerald Cheng, an alert preparedness meteorologist at Environment and Climate Change Canada, said it was difficult to predict whether the temperature increase would last in the months following, but he agreed with Farnell that September is “going to be above normal.”
“It’s less clear as we see in October and even further into November, there’s a signal coming back that it’s going to be above normal, but there’s less confidence,” Cheng said.
