A couple of years ago we had amazingly cold weather here in Puerto Rico too.
People that lived in the mountainous elevations even had to go and buy coats,hats,gloves and scarves! That's how unreal cold it got!
And some folks went and bought little electric heaters.
Thinking that might be an idea for your balcony in case temps go down again. You never know, and it might help some. Here's hoping it stays hot,both here and there. It's been pretty chilly at night here too
