Key West's water is calmest in the settled months, and that's when sandbar trips are at their best — the flats stay flat and clear. Winter cold fronts can push through and chop the water up for a day or two at a time, while summer runs hot but the water is usually glassy. Whenever you come, both sandbar trips and tiki boats run year-round.
