Just before Christmas 2007 my brother and I went to Key Largo to dive with an operation called Scuba-Do. It was my first time diving in Florida and I was very pleasantly surprised by the extensive variety of marine life. The diving conditions also gave me a pleasant surprise. Water temp was 75 degrees, the coldest I've experienced yet, but I was not cold at all, even at depth exploring the U.S.S. Spiegal Grove. Visibility usually ranged between 25 and 35 feet, which was definitely good enough to stay safe and enjoy the diving.
