Peak hurricane risk
September is inside the Atlantic hurricane season. A storm can change a port day or the whole route, so keep your plans here flexible.
Grand Cayman in September is warm and sunny, with average highs around 89°F and lows that rarely dip below 77°F. September sees roughly 13 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Peak hurricane risk.
It's the shoulder season in Grand Cayman: fewer crowds than the winter peak, but the heat and humidity are at their highest. A light rain jacket and early-morning excursions will serve you well. Pack reef-safe SPF 50+ sunscreen, a hat, and breathable fabrics. The sun at 89°F is intense, especially near the water.
