Is December a Good Time to Visit the Bahamas?
Yes. December is a good time to visit the Bahamas if you want warm weather with less rain and humidity than during the wetter part of the year.
The Bahamas Department of Meteorology describes the cooler season as drier, with trade winds and occasional cold fronts arriving from North America. Most days are suitable for beaches, sightseeing, boating and other outdoor activities, although the weather is not as consistently hot as it is in midsummer.
How Warm Does It Feel?
Afternoons are usually comfortable for beach activities, with temperatures near 80°F. Evenings can feel noticeably cooler, especially after a cold front brings a northerly wind.
The official Bahamas tourism authority recommends packing a jacket or sweater for cooler evenings. Light summer clothing is generally suitable during the day.
Does It Rain Much in the Bahamas in December?
December is part of the Bahamas' drier season. Showers are generally less frequent than during the wetter summer period, although a passing front can bring cloud, rain and stronger winds for a short time.
Rain rarely dominates a trip, but clear skies are not guaranteed every day. Trade winds often bring bright conditions, while passing weather systems can change the forecast for a while.
Is the Ocean Warm Enough for Swimming?
The sea is generally warm enough for swimming. Official Bahamas tourism guidance lists average December water temperatures of approximately 75°F to 78°F (24°C). Some swimmers may find the water cool after a windy day or a cold-front passage.
For extended dives, the Bahamas tourism authority recommends a 3 to 5 millimetre full wetsuit, depending on personal comfort and sensitivity to cold.
Does the Weather Vary Between Bahamian Islands?
Yes. Weather varies across the Bahamian islands, particularly during cold fronts and windy periods.
- Northern islands, including Grand Bahama and the Abacos, can feel cooler during cold fronts.
- Nassau and New Providence provide a useful central reference for typical temperatures.
- Southern islands, including Great Inagua, are generally warmer and drier.
- Wind exposure varies by location, especially on smaller islands and open beaches.
The Bahamas Department of Meteorology identifies a cooler, wetter northwest and a warmer, drier southeast across the archipelago.
What Should You Pack?
Pack for warm afternoons, cooler evenings and occasional wind:
- Swimwear and light summer clothing
- Sunscreen, sunglasses and a hat
- A light sweater or jacket for evenings
- A lightweight windbreaker for boat trips
- Comfortable walking shoes
- A light wetsuit if you plan long dives or are sensitive to cooler water
Bottom Line
December suits travelers who want warm days, relatively low rainfall and good conditions for outdoor activities. Bring a light layer as well as beachwear, since cold fronts can bring cooler evenings, stronger winds and occasional rain.
