6. Florida

Cold fronts often dip deep into Florida, but by March the weather warms, making the west coast’s cruising grounds of Charlotte Harbor’s Pine Sound and the Fort Myer’s Caloosahatchee River a getaway spot. There is plenty to explore among Gasparilla, Captive and Sanibel islands where you will find state parks and plenty of shelling beaches. If you want guaranteed warmth, look farther south to the Florida Keys and Dry Tortuga, which boasts cruising spots with laid-back Keys life.
