And -20 C isn't that cold for outside and close to the floor either. There are places that occasionally reach both. But none of them would be anywhere close to a sea, so perhaps they simply didn't mind extending the temperature range because they start with their domestic market?

If it's the latter, a few dozen hours a year certainly wouldn't matter a lot.
