We went to Islamorada last year and it was so cold no one would take me out diving (and I didn't blame them a bit). So I bought a bunch of cold gear with the money I saved and froze to death snorkeling among all the dead stuff. Truly was amazing the amount of stuff that died on both the ocean side and gulf side in the keys.
We went to the dominican this year and I didn't even get to snorkel. The rip was so bad that the red flags were out the whole time we were there. Two days prior to our arrival, our hotel lost two guests to the surf.
We'll see what next year brings.
