Climate in Key West

Like most tropical climates, Key West has two seasons wet and dry climate. The period from November through April is normally sunny and quite dry, with only 25 percent of the annual rainfall occurring. This rainfall usually occurs in advance of cold fronts in a few heavy or light showers. May through October is normally the wet season. During the wet season some rain falls on most days, often in quick tropical downpours, followed by intense sun. Early morning is the favored time for these showers, which is different from mainland Florida, where showers and thunderstorms usually occur in the afternoon. Easterly (tropical) waves during this season occasionally bring excessive rainfall, while infrequent hurricanes may be accompanied by unusually heavy amounts. At any rate, Key West is the driest city in Florida
