I know this might trigger Huffy but...
We are in Fort Lauderdale right now for a couple of days before a cruise, right on the beach. It is miserable hot and muggy! Every time I have been here (always summer or spring) it is unconfortably muggy and usually way too warm. I don't even want to go outside.
Perhaps if I visited in December I would have a different opinion. But I feel like, if I had to live here, I would be compelled to go somewhere else at least half the year. I don't like it at all. California is so much better for beach life. Or even north Atlantic like Delaware or Maryland - those trips were so much more comfortable and enjoyable.
