March: Myths About Spring Diving in Key West

April offers enviable diving conditions with water temperatures in the high 70s°F and visibility often impressive. The air temperature averages in the 80s°F, setting a comfortable backdrop for a day of diving.

Enhance your diving experience by following essential tips: book dives early, especially for popular sites like the Vandenberg Wreck. Morning sessions are optimal as seas are generally calmer. Check forecasts for passing showers, though they rarely disrupt activities. Local shops provide insights on sightings, such as migratory tarpon or nesting sea turtles.
