Here in quasi-coastal NC, I'm down to maybe 10 days a year wearing long pants. It got up to 71F New Years Day this year, and February had days in the 80s (and none below freezing). There's basically pollen season, summer, fall, repeat. It doesn't seem to be much colder, if at all, in January than November. i barely ever see my breath.
Not at all how it was in the exact town 35 years ago as a kid. It wasn't frigid, even then, but we had a real Winter season where it would consistently stay cold for 3-4 months.
Now, even though it can get cold, it seems like you have a "nice day" weekend at least once a month.
