Grand Cayman is the largest of the Cayman Islands and a regular western Caribbean port. Seven Mile Beach runs down the island's west side, calm and lined with beach bars. At Stingray City, a shallow sandbar offshore, you can stand in waist-deep water while southern stingrays glide past your legs.
Grand Cayman in August is warm and sunny, with average highs around 90°F and lows that rarely dip below 78°F. Expect around 11 rainy days, typically brief afternoon showers rather than all-day rain. Morning excursions are usually the safest bet. Hurricane season, daily showers
Crowds are moderate in August, making it a good balance between availability and weather. Pack reef-safe SPF 50+ sunscreen, a hat, and breathable fabrics. The sun at 90°F is intense, especially near the water.
