Doesn't feel like November

We have been here about 15 months and at least this year, I noticed it cooling from the heat of summer. Today it is 27 degrees and beautiful. I went and sat outside with my Kindle for an hour. As I walked back, I had to remind myself it is December next week. It doesn't feel like that though the shops are full of Christmas things. It will feel cold when we go back.
However the locals are wearing jackets and boots. I can't see when I will be doing that.
