There's no bad time of year to visit Martinique, also known as the rum capital of the French Caribbean. Though the island is beautiful all 12 months of the year, the chance of storms and rainfall in Martinique is known to fluctuate from season to season. As the island is located within the Hurricane Belt, travelers should be advised that August through October is the riskiest time to visit in terms of tropical storms. So, visitors arriving in Martinique during this time period should consider purchasing travel insurance in advance of their visit. January through April are the driest months of the year, though they also fall within the peak tourist season on the island, so visitors should consider booking in advance if they're planning a winter vacation on this island in the French Caribbean.

Hurricane Season in Martinique

Though Martinique is consistent year-round when it comes to sunshine for visitors to sunbathe beneath and invitingly warm Caribbean waters for travelers to swim, Martinique is nevertheless susceptible to tropical storms and hurricanes that can sweep through the Caribbean in the summer and fall seasons. The hurricane season officially begins in June and lasts through November, though the storms are most likely to hit in August, September, and October. (September is known to be the most volatile month of all.) Travelers visiting Martinique during this time period should consider booking travel insurance. There is always a chance of rain whenever you visit this island in the tropics—as is the case throughout the Caribbean Sea—though locals (and blissed-out visitors) prefer to look at the afternoon showers as liquid sunshine.

Spring in Martinique

March and April are ideal times to visit as it is slightly cooler than it will be in the summertime and less rainy than it is during the hurricane season. Also, as of mid-April, it is no longer peak season in Martinique (and the Caribbean at large), as the last of the spring breakers fly home. As a result, prices will be lowered and visitors can score better deals on trips. During the springtime, the average sea temperature is 79 F (26 C) in March, 81 F (27 C) in April, and 82 F (28 C) in May.

What to Pack: Sun protection; Water shoes or sandals; Hiking boots for adventuring in the mountains; a light scarf or sweater for the evening; A raincoat just in case of showers (though it is the driest time of the year)

Average Temperatures by Month:

  • March: 84 F / 72 F (29 C / 22 C)
  • April: 86 F / 72 F (30 C / 22 C)
  • May: 86 F / 73 F (30 C / 23 C)

Summer in Martinique

The average sea temperature is 82 F (28 C) in the summer months of June, July, and August. June is the windiest month of the year and is the official start to the hurricane season in Martinique, which officially concludes in the month of November. Beginning in July through to November kicks off the hot, rainy season. But keep in mind it can rain all year-round, so it's not necessarily a reason for travelers to avoid visiting. But worried guests should purchase travel insurance in advance.

What to Pack: Given that it will be raining more, pack a raincoat in case of showers; light-weight clothing to withstand the heat; sun-screen, hat, and sunglasses for protection from the tropical sun

  • June: 86 F / 75 F (30 C / 24 C)
  • July: 86 / 75 F (30 C / 24 C)

Fall in Martinique

Fall is hurricane season in Martinique, though it officially begins in June, the peak is between August and October. Though the chance of storms is a deterrent to many visitors, there's no guarantee one way or the other whether your trip will be affected (as is the nature of life on the Hurricane Belt), so would-be visitors shouldn't be entirely deterred. (And cautious travelers can always purchase hurricane insurance in advance.) The price of travel is also lower during this time period, and it's easier to book deals on hotels and airfare. November concludes the last month of the stormy season and is the most humid. (The average annual humidity in Martinique is 83 percent.) The average sea temperature is 84 F (29 C) in September and October, the best months for swimming, and drops slightly to 82 F (28 C) in November.

What to Pack: Rain-gear in case of storms (jackets, umbrella); sun protection for the heat; reef-friendly sunblock to avoid damaging the coral, and snorkeling equipment for underwater explorers

Average Temperatures by Month:

  • September: 88 F / 73 F (31 C / 23 C)
  • October: 88 F / 73 F (31 C / 23 C)
  • November: 86 F / 73 F (30 C / 23 C)

Winter in Martinique

Though the hurricane season has officially passed, December and January are a bit rainier than February; but all three months are far drier and milder than the summer/fall storm season. February and March are the coldest months for swimming, though the weather is still outrageously warm by any standard. The average sea temperature is 81 F (27 C) in December and January, dropping to 79 F (26 C) in February. The wintertime kicks off-peak tourist season in Martinique, so budget-conscious travelers should book flights and hotels in advance in order to save on the cost of travel. Guests who do visit Martinique during these winter months can look forward to partaking in holiday celebrations in late December.

What to Pack: Sun protection, hiking boots or sneakers for outdoor exploration, a light sweater or scarf for the evening, and a rain jacket for tropical showers
