Flag - Martinique

Martinique has a hot and humid climate throughout the year, with limited temperature variations: during the day it goes from 83 degrees Fahrenheit in the "winter" months (December to February), to 86/88 °F in the "summer" months (May to October). The relative humidity is above 70% even in the afternoon. During the cooler period, from November to April, the north-east trade winds, steady winds typical of tropical climates, blow regularly.
Here are the average temperatures recorded at the airport.

Martinique is an island which has the status of a French overseas department, with Fort-de-France as the capital.
The rainfall is abundant: on the coast, 80 inches of rain per year fall, of which more than 4 inches per month from May to December, and among these, more than 8 in from July to November, which is the rainiest period. The least rainy period goes from February to April, with 2.6/3.5 in on average, so there is not a real dry season. On the slopes exposed to the northeast trade winds, especially those of Mount Pelée, 4,583-feet high, the rains are more abundant, so that the climate can be called equatorial, as evidenced by the lush vegetation.
Here is the average precipitation in the capital.

The rains in Martinique occur throughout the year especially as downpour or thunderstorm, hence they do not reduce too much the sunshine hours, except when the island is affected by tropical cyclones, called hurricanes in this region. Hurricanes may occur from June to November, but are most likely from August to October, as in all the Antilles.


The sea is pleasantly warm all year round, as we can see from the following table.

When to go

The best time to visit Martinique goes from February to April, which is the least rainy period. December and January are still rainy, but less than in the peak period of July-November: considering that they are in the least hot period, and that, however, there may be some showers in all seasons, in the end, you can also choose December and January.

What to pack

All year round: light clothes of natural fabric, possibly a light sweatshirt and a light raincoat for thunderstorms; a light sweatshirt for the evening from December to March.
For the reef, equipment for snorkeling, water shoes or rubber soled shoes.
For climbing Mount Pelée, walking shoes, a light sweatshirt and a light raincoat.
