Rest of September expected to remain warmer than normal

Welcome to the new season, much like the old season.

With mild temperatures in store for the first day of fall Wednesday and the rest of the week, Environment Canada’s Peter Kimbell uses a fairy-tale reference to describe the conditions Southwestern Ontario experienced during the now-concluded summer.

“We had kind of a Goldilocks summer,” the warning-preparedness meteorologist said Tuesday, by which he means it wasn’t too hot, nor ever too cold.

Asked why the weather panned out that way, Kimbell says he would like to point his finger at El Nino, the tropical ocean-temperature phenomenon, but he can’t. “Weather is inherently variable, even without El Nino,” he explained.

The hottest day of the summer in London came relatively recently, on Sept. 7, when the mercury climbed to 31.9 C.

September has been 4 degrees warmer than normal, according to Kimbell. “We’ve basically extended summer by one month,” he said. “The rest of September is looking like it’s going to continue to be warmer than normal.”

The mean temperature for June was 18 C, for July 20.2 C, for August 19.5 C, for September to this point 19.2 C – but that’s likely to fall a bit by the time the month finishes.

The mild conditions of the last couple weeks are likely to extend into October and maybe even November, he believes. “The temperatures do start to plummet in September,” Kimbell said. “Frost will, of course, arrive at some point in October.”

As for the idea that the transition seasons of autumn and spring are being squeezed out so that we are either roasting or freezing all the time, Kimbell says that’s another myth: “No, that’s a perception, I think. There’s definitely transitions.”
