Wait 'til tonight and the next few nights. The forecast is for it to go down to lower 60s.
The end of March of last year was my first winter. FL residents had just gotten through the worst winter in this part of FL in decades. Sadly, people lost thousands of dollars in landscaping and plants. When I moved in here I walked around in shorts. And within two weeks I felt I was in a tropical Paradise. I stored away my winter socks, heavy jackets, gloves, and ice scrapers.
I'm not sure if you have been hearing this but all over the world the weather has been changing. In many areas the whole northern half of the globe has been having cold wet and unseasonal summers. For example, my friends in UK, Switzerland had wet cold summers with little hot days. Just recently now they're getting summery days. And yet Houston has had hot and the worst and longest drought in decades.
