Climate of Bahamas
Country climate guideThe Commonwealth of The Bahamas is a chain of more than 700 islands spread over some 800 kilometres of the Atlantic, between about 20 and 27 degrees north. Because almost none of the land rises more than a few metres above sea level, the ocean controls the climate almost completely. The result is a year-round tropical climate with mild winters and no cool season.
Main climate types
The islands are classed as tropical, though they sit on the northern edge of that zone and behave more like a subtropical desert-maritime regime than a rainforest one. Rainfall is modest and seasonal: the wettest months are usually May to October, when the intertropical convergence zone reaches this far north and showers arrive with tropical systems, while the winter months of December and January are dry and dominated by the northeast trade winds. Hurricanes and tropical storms forming between June and November are part of the yearly pattern and can drop a year's worth of rain in a single day.
Temperatures
Temperature varies far less than rainfall. Mean monthly values at Nassau sit near 21 °C in January and 27 °C in July, and the difference between the coldest and warmest month is only about 6 °C. Nights rarely drop below 15 °C in winter, and sea surface temperatures stay between roughly 22 °C and 29 °C all year, which makes swimming pleasant in any month.
Rainfall
Annual precipitation averages roughly 1,000 to 1,200 mm on New Providence and similar amounts elsewhere, making the Bahamas one of the driest places in the Caribbean. Most rain falls as brief, heavy showers. Humidity stays high for much of the year, although the steady trade wind usually stops it from feeling oppressive. The coolest nights of the year in the northern islands come with cold fronts sweeping down from the North American mainland.
When to go
Visitors who want dry, sunny weather should come between January and April, when the trade winds are strongest and the risk from tropical cyclones is lowest. Summer and autumn are hot, humid and more prone to showers, storms and occasionally a hurricane, and they are also the cheapest weeks of the year. There is no true cold season anywhere in the country.
