As part of the fall rainy season, hurricanes occasionally sweep through the Caribbean. Check the news daily and keep abreast of brewing tropical storms. The rainy season consists mostly of brief showers interspersed with sunshine. You can watch the clouds come over, feel the rain, and have the sun to dry you off, all while remaining on your lounge chair. A spell of overcast days is unusual, as everyone will tell you.

The Caribbean high season is traditionally winter -- from December 15 to April 14 -- when northern weather is at its worst. During this season, travelers are guaranteed the most entertainment at resorts and the most people with whom to enjoy it. It's also the most fashionable, expensive and popular time to visit. As a result, most hotels are heavily booked. Make reservations at least two or three months in advance for the best places (sometimes a year in advance for the most exclusive spots). Hotel prices drop 20%-50% after April 15.
The only time to consider not going to the Turks and Caicos is the sweltering four months of August to November, when the daily average high is 32°C (90°F); when the trade winds die it nudges over 38°C (100°F). Probably the best time to visit is between mid-April and July.
