The wettest months are May to June and September to October while the driest are February and March. You’re guaranteed sunshine and perfect conditions for diving and swimming all through the year.

Seven Mile Beach is one of the island’s most popular destinations, and also the busiest. It is one of the most spectacular stretches of white coral sand in the world, and there are shops, bars and restaurants to suit every taste. Try snorkelling around Cemetery Reef or take a guided dive to one of the shipwrecks that dot the coastline. Feed the incredibly tame stingrays at Stingray Point, and be sure to visit the Cayman Turtle Farm.
