What March feels like
March brings spring break energy to Duval, though Key West has always been a very different animal from the mainland party beaches. Visibility on the reef is at its best this time of year, which is why the dive boats fill first.
Real rain shows up about 3 days all month; the rest stay dry. There’s a little humidity in the air, but nothing that changes your plans.
Can you swim?
The ocean runs about 78° — bath-warm.
