I moved here a few months ago from New Jersey, and felt the same thing - I would use the pool all year. Well you really don’t feel like using the pool when it is between 30-50 degrees. Even if you did, it would cost a bloody fortune to keep warm even with a solar blanket on it. I always stretched mine in NJ opening first week in April and closing mid-October. A lot depends where you are in Florida. If I was in Miami I might use it all year, but even then not sure. Up in the Jacksonville area which is the extreme North East of the state we actually have seasons and it gets cold.
