St. Maarten/St. Martin is split down the middle: the Dutch territory of Sint Maarten to the south, the French collectivity of Saint-Martin to the north, two countries on one small island. Cruise passengers dock in Philipsburg on the Dutch side, minutes from beach clubs, duty-free shops, and Maho Beach, where jets clear the sand by a few feet on their approach to the airport. Cross into Marigot on the French side for the food.
St. Maarten / St. Martin in August is warm and sunny, with average highs around 90°F and lows that rarely dip below 78°F. August sees roughly 14 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Hurricane season, daily showers
It's the shoulder season in St. Maarten / St. Martin: 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 90°F is intense, especially near the water.
