I'm certainly enjoying today's 4C dry mid-winter weather in Toronto, with more of the same on tap for the next few days. However, I'm not sure I agree with the definition of "mild" weather described in the article (18C to 30C). To me, mild, or comfortable, daytime highs range from 12C to 24C, although to a great extent this is dependent on the season. A high of 12C in June would be cold while it would be really nice in November. A high temperature over 24C, especially when combined with the summer humidity that's a virtual certainty in places like southern Ontario, is essentially hot weather in much of the country.
