Bahamas weather is predictable in the fall when the islands usually receive a high amount of rain, but it doesn’t stop Caribbean vacationers from flocking there.
The islands are the most popular tourist destination in the region – mainly because of the large number of cruise visits embarking from various U.S. ports along the Gulf of Mexico and the east coast.
Weather in the Bahamas is cooler and rainier than most other places in the region.
Even though the islands are thought of as a Caribbean destination, in reality they lie north of the Caribbean.
The northern location results in cooler air and water temperatures from late fall to early spring.
The average monthly high temperature is about 84 degrees Fahrenheit, according to the World Meteorological Organization.
The average monthly low temperature is 69.5 degrees. The average Bahamas temperature is among the lowest in the region in part because the islands lie north of all other Caribbean destinations.

Best Time to Go to Bahamas
The best time to go to the Bahamas is late spring because of a combination of warm temperatures and lower risk of rain.
Anyone planning to visit the islands who wants to enjoy ocean swimming should avoid Bahamas weather in December through March because of cool weather.
If cool beaches and water aren’t an issue, winter is a good time to visit because of the low chances for rain.
Visitors also should avoid Bahamas weather in June through October – and especially June and August – because of rain.
