January weather forecast
Martinique

January marks the beginning of the calendar year in Martinique and is considered part of the island's winter season. It is one of the cooler months, with the average temperature standing at 25°C (77°F). The cooler weather is especially evident in Fort-de-France, the capital city, which is nestled between mountains and the Caribbean Sea, allowing the trade winds to moderate the temperatures further.

Compared to December, January experiences slightly lower temperatures but similar weather patterns. The island maintains its tropical heat with daytime temperatures ranging between 22.2°C (72°F) to 29.4°C (84.9°F), a welcome respite from the hot and humid conditions characteristic of the wetter months.

The rainfall during January is relatively low, making it a part of the drier season of the island. Despite its position in the winter months, January does not witness any snowfall due to Martinique's tropical rainforest climate.

The winds in January are among the strongest of the year, averaging between 20.9km/h (13mph) and 29km/h (18mph). This brisk wind flow enhances the pleasant conditions along the coastline, especially on the sandy southern beaches of Les Salines.

The month also experiences a relatively clear sky, with overcast conditions only up to 36% of the time. Such weather ensures an average of more than 11 hours of daylight, making outdoor activities and sightseeing enjoyable. Despite the season, the seawater temperature remains warm, ranging from 26.1°C (79°F) to 28.9°C (84°F), thereby supporting water-related activities and swimming.

While January provides relief from the island's typical heat and humidity, it also serves as a prelude to the warmer and marginally wetter conditions of February.
