January Beach Weather
January is an excellent time for a Saint Martin and Sint Maarten beach holiday. The islands enjoy warm, generally settled weather, with daytime temperatures often around 28°C and pleasantly cooler evenings. Sea temperatures remain inviting, so you can move easily between swimming, snorkelling and simply relaxing beside the water.
This is also one of the drier parts of the year. A brief shower can still appear, but it usually passes quickly and leaves the afternoon bright and fresh. With plenty of sunshine and a comfortable breeze, January is ideal for escaping the colder, darker weather in the United Kingdom.
