The best time to dive in the Caribbean is from late November to May. Most countries and dive areas within the Caribbean are great for diving year-round. However, from June until early November, hurricanes are a distinct possibility throughout the Caribbean Sea. While it is unlikely that your trip will be influenced by one of these massive storms, many liveaboards scale back the number of dive safaris offered during these months. If you do book a trip during hurricane season, be sure to also buy trip insurance in the case that your liveaboard is canceled due to inclement weather. Water temperatures vary from destination to destination, but you can generally expect tropical waters. Temperatures generally average between 79-84°F (26-29°C) with the warmest temperatures occurring from April to November. Like water temperature, visibility can vary from island to island in the Caribbean. Because you’ll be diving from a liveaboard, you’ll experience the best visibility in this part of the world. Visibility at remote dive sites can reach up to 100 feet (30m) although more often you’ll have visibility between 50-65 feet (15-20m). Finally, surface conditions during hurricane season and rainy season are likely to be at their worst. If you are prone to seasickness, it is recommended that you visit during dry season from November to May.
