Having a temperature system for normal Earth humans that only ranges from -10 to 30 degrees makes no objective sense. Centigrade units is the only part of the metric system that I have serious problems with.
And I call it centigrade because it sounds cooler.
Yes, though 0 being freezing makes some good sense, I think.
Also, the weather you describe sounds like where I am. You in the northeast?
If you flip a map upside down, then, yes, I am in the northeast. Otherwise, no.
That area of the country does sound lovely, though.
