I have an N2B parka jacket I bought years ago and I didn't wear it once last year now that I think about it. We'd usually always get a Indian Summer, but it was very brief and only through early September, not all the way into October.
Like I mentioned it doesn't feel right at night time. Climate change is very real.
I'm still having to run my air conditioner at night. The only positive I can think of is at least we're having a period of actually tolerable temperatures after such an unbearable summer before it starts getting cold. But even last year I was having to start to run the heaters by mid-October, guess that's no longer the case moving forward.
