When to go

May is the last month before the official Atlantic hurricane season, which the National Hurricane Center says begins in June. The National Weather Service's Melbourne table lists higher average temperatures and more rainfall for May than for April, so keep some flexibility in outdoor plans. Memorial Day, a federal holiday, closes the month, and Visit Orlando lists Orlando Carnival Downtown events on the weekend leading into it, so check those dates against your trip.
