Grand Cayman Water Temperature
Grand Cayman is the largest of the three Cayman Islands, and one of the most beautiful destinations in the Caribbean. It’s easy to reach and there are regular flights to Owen Roberts International Airport.
Scuba diving and snorkelling are some of the most popular pastimes, and there are several shipwrecks near the shore as well as a number of coral reefs. George Town, the island’s capital is picturesque, and the famous Seven Mile Beach to the west of the town is considered among the most beautiful in the world.

Grand Cayman enjoys a typical Caribbean climate with hot summer days that can be humid at night, and warm winters with cool nights. Summer humidity is relieved by the cooling sea breeze and though there is a rainy season from May to November, rainfall tends to be in the form of tropical downpours during the night. 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.
You should see this when you visiting Grand Cayman
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.
