It seems they did some work on coming to a definition for “mild weather,” but I still don’t like what they came up with. They set the range at 10-25 degrees Celsius. I would have set the lower boundary at -10 or maybe even a bit lower. It’s somewhere below that the majority of people stay inside their ice-fishing shacks instead of getting out a chair to enjoy the weather.

Of course, the number of people I know in Saskatchewan who think only lunatics go out at those temperatures may mean that they’ve nailed it. :)
