Agree - it felt fantastic! Even during the day it was very enjoyable (we were doing Disney so no pool access during the day). Mexico was downright hot but I was in the pool all day there. Coming back to 40 degrees and the smell of smoke (renters had stove going) felt like the transition from summer to fall.
Off topic, but really sad situation down in Mexico. Beaches that used to be immaculate were covered in sargassum. Apparently it's been happening for 2 years. Some attribute it to global warming and pollution but it's not entirely clear. Still, heavenly places like Akumal which had swimming pool like coastline now have brownish water and piles of algae everywhere. It's sad. We went diving and you notice a thick brown layer in the top 20 ft or so of water. The reef don't seem affected... For now. But it's a stark wake up call and reminder of what we are doing to this planet.
