Bahamas Weather in August: Heavy Rains

Bahamas weather in August historically has some of the highest rainfall of the year.

The Bahama islands are the most popular destination in the Caribbean region thanks to five million cruise and 1.5 million hotel visitors who vacation there over multiple nights.

Oddly enough, the Bahamas are popular in August even though historically the islands have the highest amount of rain during the month than any other time in the year.

The Bahamas aren’t technically part of the Caribbean because they lie just north of the boundary for the Caribbean Sea. But they have many of the same weather patterns as the rest of the region.

Average Rainfall

A 30-year history shows that the Bahamas average nearly 10 inches of rain and 19 days of rain during August, according to the Bahamas Department of Meteorology. That makes August the worst month of the year for the risk of rain.

By comparison, June is the next worst month with about eight inches of rain and 15 rain days. July, September and October average about six to seven inches each.

The Caribbean hurricane season officially runs from June 1 through Nov. 30. The peak month for storms and hurricanes for most destinations is September with October being the second worst. The Bahama islands are unusual for getting the worst weather in August.

Rainfall during the year hits a low point during the cooler winter months when rainfall averages about two inches a month.

Temperatures are consistent with other summer months.

The average high temperature in August for Nassau Bahamas is nearly 90 degrees Fahrenheit or 32 degrees Celsius, according to the Bahamas Department of Meteorology. The average low is 75 degrees Fahrenheit or 24 degrees Celsius. The lows usually take place at night.

By comparison, the average daytime highs drop into the upper 70s Fahrenheit in December and January. Unlike winter, water temperatures in August will feel comfortable for swimming.

Tourism: Still Popular

Cruise visits to the Bahamas may decline in August because of the high risk of rain, but the islands remain popular with overnight hotel visitors.

In fact, September through the following February are less popular months.

They are less popular during the fall because of the threat of rain, even though the average rainfall is lower during that time.

They are less popular during the winter because of colder temperatures that make swimming and other water sports uncomfortable.


Nassau has one major event, which is the Goombay Summer Festival every Friday in Arawak Cay.

The festival features limbo and fire dancers, food demonstrations, traditional Goombay dancers, rake n’ scrape bands, Androsia fashion, a kids’ corner, face painters, magicians, a grand Bahamian concert and a Junkanoo Rush Out.

Another regular event in Nassau during August is the Miss Bahamas Beauty Pageant.

Grand Bahama has High Rock’s annual homecoming festival, which celebrates the bounties of the sea in early August. Entertainment includes local bands, a Junkanoo Rush-out, and all you can eat fish, conch and lobster. The festival takes place at the High Rock Primary School.


Vacationers who want to visit the Bahamas should choose another month to go such as May, which has a better combination of warm temperatures and low chances of rain.

Anyone who must go in August should consider a cruise instead of a hotel vacation. A cruise may go to other ports and limit the amount of time in the Bahamas during the rainiest time of the year.
