The Bahamas splits the year into a wet season and a dry one, with a hurricane season layered over the back half of the wet months. The wet season runs late May to October and the dry season November to April, according to the Department of Meteorology, and most of what you need to plan around follows from where your trip falls on that calendar. The archipelago stretches across a few hundred miles from the Abacos in the northwest to Inagua in the southeast, so conditions on the day you land can differ noticeably depending on which island you have booked, even within the same season.

The wet season

Rain builds through the summer and peaks in August, the wettest month at New Providence, averaging 9.28 in (235.46 mm). Showers in this stretch tend to be short, heavy afternoon downpours rather than days of steady rain, but they are frequent enough to plan flexible outdoor days around rather than fixed ones.

The dry season

Rain tapers off sharply once the dry season sets in. January is the driest month, averaging 1.86 in (47.24 mm) at New Providence, and cold fronts moving down from the US are the main source of what winter rain there is, arriving roughly once every five days. This is the more reliable season for a trip built around beach or boat days.

Shoulder seasons

Late April to May and November sit between the two main seasons and are worth considering if you want to dodge both the heaviest rain and the hurricane risk window. By then the wet season’s afternoon downpours have not yet built up, or have already tailed off, and the storm threat is at its edges rather than its peak. Humidity is lower than at the height of summer, water temperatures are still warm from the season before, and the islands are quieter between the winter rush and the summer one. The trade-off is a shorter window of settled weather than you get in the core dry season, so build in a day or two of flexibility either side of your dates.

Hurricane season

The official Atlantic tropical cyclone season runs June to November, but the practical risk window for the Bahamas is narrower: storms that actually affect the islands concentrate from mid-July to October, with August, September and October the months of highest frequency. A trip booked for peak hurricane season is not a reason to cancel outright, but it is worth travel insurance and a flexible itinerary, especially on the Out Islands where evacuation options are fewer.

Temperatures

On New Providence, winter is mild rather than cold: lows seldom fall much below 60°F (16°C), with afternoons near 75°F (24°C). Summer is warm and fairly humid, with nights around 78°F (26°C) and days rarely above 90°F (32°C). Winter runs a few degrees warmer in the southern islands than in the north, while summer temperatures are similar across the archipelago, so the temperature swing by island matters more in January than in July.

Rainfall by island

Annual rainfall varies considerably by geography: it averages about 60 in (1,524 mm) a year at Abaco in the northwest, falling to less than half that at Inagua in the southeast. An Out Island trip in the northwest should expect a noticeably wetter climate than the same dates in the far southeast.

Practical tips

  • Favour November to April for the most reliable dry-weather trip, and expect short, heavy afternoon showers if you travel in the wet season instead.
  • Treat mid-July to October as the period to watch most closely for tropical storms, even though the official season runs June to November.
  • Pack for mild rather than cold winter nights on New Providence; a light layer covers the coolest evenings.
  • If your island is in the northwest (Abaco and similar), budget for wetter weather overall than a trip to the southeast (Inagua and similar) at the same time of year.

What to check before you go

  • The National Hurricane Center’s current outlook if you are travelling July to October.
  • Your travel insurance’s storm and cancellation terms before booking a hurricane-season trip.
