Grand Cayman is the largest of the Cayman Islands and consistently ranks among the top Caribbean cruise destinations. Seven Mile Beach is one of the finest stretches of sand in the Caribbean — calm, clear, and lined with beach bars. Stingray City, where you can swim with friendly southern stingrays in shallow water, is one of the most memorable shore excursions in the region.
Grand Cayman in May is warm and sunny, with average highs around 87°F and lows that rarely dip below 75°F. Expect around 7 rainy days, typically brief afternoon showers rather than all-day rain. Morning excursions are usually the safest bet. Getting hot, some showers
Crowds are moderate in May, making it a good balance between availability and weather. Pack reef-safe SPF 50+ sunscreen, a hat, and breathable fabrics — the sun at 87°F is intense, especially near the water.
