Rob Kuhn, a severe weather meteorologist at Environment and Climate Change Canada, says the normal high temperature for the first week of October is between 15 and 17 C, but this weekend's highs could reach around 27 to 30 C across southern Ontario. Kuhn says such weather patterns aren't unprecedented as highs into the 20s and up to 30 C have been recorded in the past, but Ontarians don't get to experience July-like temperatures in October too often.
Since the equinox on September 22nd, and the start of astronomical autumn, France has shivered in an unseasonably cold spell with temperatures about 5C below normal for the time of year. "The succession of cool, grey days in September is unusual," national forecaster Météo France said in a statement. The lack of sunshine is also part of what makes this situation remarkable."
