Traveller notes on Fort-de-France in May
Notes from nearby Castries (69 km away)
Fort-de-France doesn't have its own notes for May yet — these are about Castries, close enough to share the season.
May is the last month of the dry season here, which runs December through May, and regulars call the handover to the wet months an unremarkable one - the same hot days and nights with occasional showers, storms that come in fast and leave just as quickly. Our row backs that: 37.3mm across 11.4 days is a real but modest total. Air is 30.5C reading as 33C, though at 72.4 percent humidity it is milder than the number implies, and they credit the constant wind off the ocean, which our column carries at a genuine 24.1 kph. Nights hold 24.9C, the sea 28C. Prices ease and booking gets easier as the dry season's crowds thin out. The record: 11.7 hours of sun and AQI 48.
Other months in Fort-de-France
February is carnival, and in Martinique that is not a sideshow - most of it happens in downtown Fort-de-France, and the forum's practical warning is about supplies rather than weather, because the shops largely close during it and groceries become hard to find. The set piece people name is Bet a Fe, the night parade of lights, costumes and music that starts around seven in the evening. The weather underneath is dry-season Caribbean, and our row shows its shape: 15.3 precipitation days carrying only 44.5mm between them, which is passing showers rather than wet days, under a steady 22 kph trade wind. The record: 26.7C days that feel like 29C, 23.9C nights, 10.7 hours of sun and a 26.4C sea.
Forum posters describe September as roughly a coin flip day to day - about half the days perfectly nice and sunny, the other half bringing wind systems, cloud and higher winds. When rain falls, posters describe it as widely scattered and often brief, sometimes just a few minutes to an hour, with one part of the island seeing rain while another half a mile away stays bright and sunny. Posters are direct about the real hurricane risk: September sits at the peak of the season, with roughly one in every two to three years bringing an actual damaging storm, alongside a general chance of a day or two of unsettled weather from a passing system most years. Posters generally frame September as a viable, lower-price option for anyone willing to accept that real risk.
Martinique's forum describes year-round weather as plenty of sunshine with occasional showers, roughly 25-31°C, and Fort-de-France on the drier southern half of the island compared to the wetter north. Regulars point to the dry-season months around March as generally reliable, with rain a real possibility on any given day but rarely enough to derail a trip.
