January Diving Conditions
January is an excellent time for scuba diving around Saint Martin and Sint Maarten. The islands sit in the warm Caribbean, where sea temperatures are usually around 26°C, so most divers are comfortable in a thin wetsuit or rash vest. Visibility is often very good, making it easier to spot reef fish, sea fans and the fascinating shapes of the underwater landscape.
This is also part of the islands’ dry season. Days are generally sunny and pleasantly warm, while gentle trade winds help keep the air comfortable. Water conditions can vary from site to site, but local dive centres know the best places to visit each day, whether you are a complete beginner or an experienced diver looking for something more challenging.
