Practical Info
Weather & Best Time to Visit
Saint Martin enjoys a pleasant tropical climate year-round, with temperatures ranging from 23 °C (73 °F) to 32 °C (90 °F). The island is cooled by steady trade winds, making the heat very manageable even in the peak of summer.
An ideal tropical climate
Saint Martin's climate is divided into two main seasons. The dry season ("Lent") runs from December to April: it's the most pleasant time, with little rain, generous sunshine and moderate temperatures. The wet season runs from June to November, with more frequent showers (usually short and intense) and higher humidity.
When to visit?
Best time
The best time to visit Saint Martin is December to April. The weather is sunny and dry, temperatures are comfortable (around 27-29 °C / 80-84 °F), and the sea stays warm year-round (26-29 °C / 79-84 °F). This is also peak tourist season, with higher prices and lower availability.
Good compromise
May and June offer an excellent compromise: prices drop, beaches are less crowded, and the weather remains very pleasant despite occasional showers.
Time to avoid
September to November is the peak of hurricane season. While the statistical risk remains low, it's the rainiest and most unpredictable period.
