The rainy season in St. Maarten (and its French counterpart, Saint Martin) typically runs from June through November, coinciding exactly with the Atlantic hurricane season. During these 2026 months, the island experiences higher humidity and more frequent, though often brief, tropical downpours. The heaviest and most consistent rains usually occur in September and October, which are also the months of highest tropical storm risk. Despite being the "wet season," St. Maarten remains one of the drier Caribbean islands, with many rainy days still featuring significant periods of sunshine. For travelers in 2026, the "Dry Season" (December to May) remains the peak period for perfect beach weather, but the "Rainy Season" offers the benefit of lush, green landscapes and significantly lower hotel rates. Just be aware that many small restaurants and boutiques on the French side may close for several weeks during the peak storm window in September.
The official rainy season in St. Maarten (SXM) runs from June through November, which also aligns with the Atlantic hurricane season. During these months, you can expect frequent but typically short-lived tropical showers, often occurring in the late afternoon. September and October are historically the wettest months, with the highest probability of storms or prolonged rainy days. In contrast, the "Dry Season" runs from December to May, with March being the driest month on record. For a 2026 traveler, the "pro-tip" is to visit in May or June; you may catch a few showers, but the island is lush and green, the prices are lower than the winter peak, and the risk of major hurricanes is significantly lower than in the late-summer peak. Despite being the "rainy season," most days still feature plenty of sunshine, as the island's geography tends to push clouds through quickly rather than allowing them to settle.
