The Climate and Best Time to Visit
The Cayman Islands are blessed with a reliably warm and sunny tropical climate, all year round. Air temperatures are consistently pleasant, typically ranging from the mid-80s°F (around 29°C) during the day to the mid-70s°F (around 24°C) in the evening. Underwater, conditions are equally inviting, with water temperatures hovering between 78°F and 84°F (25-29°C) throughout the year. A 3 mm wetsuit is generally sufficient for comfort, allowing you to focus on the world-class visibility that is a hallmark of this destination.
For divers seeking the most settled marine conditions, the period from December through April is considered the peak season, characterised by calm seas, lighter winds, and underwater visibility that often exceeds 100 feet (30 meters). This season also coincides with the arrival of eagle rays and the potential to hear the songs of migrating humpback whales in the deeper channels. Booking your Cayman Islands liveaboards trip well in advance for these months is highly recommended due to strong demand.
From May through November, the islands enter a warmer and quieter phase. While the official Atlantic hurricane season runs from June to November, the historical likelihood of a storm directly impacting the Cayman Islands is statistically low. This period offers several distinct advantages: water temperatures are at their warmest, often allowing for comfortable diving in just a rash guard, and the islands see fewer visitors. It is also a fascinating time for marine life encounters, with increased turtle nesting activity on the beaches and the intriguing chance to witness the spawning of silversides or Nassau groupers. Experienced operators of Cayman Islands liveaboards closely monitor the weather, using their intimate knowledge of the 3 islands to navigate to the most sheltered and spectacular sites, ensuring a safe and rewarding cruise regardless of the season. Whether you choose the classic calm of winter or the vibrant, relaxed atmosphere of summer, the Cayman Islands offer a world-class underwater environment ready to be explored.
