St. Maarten/St. Martin is unique in the Caribbean: the southern half is the Dutch island of Sint Maarten, while the northern half is the French collectivity of Saint-Martin — two cultures on one small island. Cruise passengers dock in Philipsburg on the Dutch side and can easily explore beach clubs, duty-free shopping, the famous Maho Beach (planes land just overhead), and cross into France for world-class dining.
St. Maarten / St. Martin in May is warm and sunny, with average highs around 87°F and lows that rarely dip below 76°F. Expect around 9 rainy days, typically brief afternoon showers rather than all-day rain. Morning excursions are usually the safest bet. Warm, occasional afternoon showers
This is one of the most popular months to visit St. Maarten / St. Martin, so book shore excursions early — the top snorkeling spots and tours sell out fast. Pack reef-safe SPF 50+ sunscreen, a hat, and breathable fabrics — the sun at 87°F is intense, especially near the water.
