Caribbean Weather in August: Temperature & Rainfall Averages

by Liz Osborn CurrentResults.com

Information on the weather in August for cities and beach towns throughout the Caribbean has been pulled together here.

The August temperatures and rainfall given in the table below allow you to compare the climate for places on two dozen islands. The monthly averages are based on historical weather records.

These temperatures are in degrees Fahrenheit. You can also view the temperatures in degrees Celsius.

Temperature

Although normally one of the hottest months for most Caribbean islands, August is only a few degrees warmer than the coolest months of the year. The ocean moderates island temperatures.

Ocean waters are also at their warmest in August with an average of around 83 degrees Fahrenheit throughout the Caribbean Sea.

Rain

August weather in the Caribbean builds up for the rainy season. This is the wettest month of the year for Nassau in the Bahamas and Port of Spain in Trinidad. It’s even rainier yet on Martinique and Dominica.

Hurricanes

Hurricane activity grows in August. The greatest chances of encountering a hurricane this month are on eastern Jamaica, Haiti, and the eastern Caribbean islands, such as Guadeloupe. Major storms in August most commonly affect Cuba and the Bahamas.

Hurricanes aren’t expected in the southern Caribbean. The region from Aruba to Tobago falls outside the Atlantic hurricane path.

Caribbean Weather in August: Best Islands to Visit

By Scott S. Bateman © Caribeez.com

Caribbean weather in August has hotter temperatures and more rain than July for most major destinations.

Cruise and resort tourism starts to decline as well in response to the riskier weather. Still, August is part of summer, and summer remains a popular time to visit the Caribbean.

Heavier rainfall starts to show up in the Caribbean in August as the annual hurricane season gets more active.

On average, the Bahamas are especially hard hit. Other destinations that often get drenched include Dominica, Guadeloupe and Martinique as well as Belize and Costa Rica. Western Caribbean cruise ports such as Cozumel and Grand Cayman get more rain than usual.

The higher risk of rain doesn’t stop people from taking western Caribbean cruises or visiting destination resorts. Some travelers get lucky and don’t experience any rain as well. But the odds do go up.

Caribbean weather in August historically averages three major storms with two that become hurricanes. The chart below shows figures from the World Weather Organization that indicate August weather averages over various 30-year periods for 17 major Caribbean destinations.

The figures are averages and may vary from one year to the next. But they show trends that help travel planners know what kind of weather to expect and whether to go in June or July instead.

Best Caribbean Islands in August

The best Caribbean islands to visit in August include Aruba – Curacao – Jamaica (Montego Bay), St. Maarten – Antigua and St. Thomas. They all average four inches of rain or less. Aruba and Curacao average about one inch; they have the lowest risk of rain in the entire Caribbean.

Caribbean islands to avoid in August include Bahamas, Barbados, Grand Cayman, Cozumel, Dominica, Guadeloupe, Martinique, Puerto Rico and St. Lucia. They all average at least five to six inches of rain historically and sometimes as much as 10 inches. The Central American countries of Belize, Costa Rica and Panama also have high levels of rain.

The longer list of Caribbean destinations to avoid is the result of the Caribbean hurricane season.

Caribbean Rain in August

Anyone wanting the lowest risk of rain will have an easy choice. Aruba and Curacao historically average about one inch of rain each August.

The ABC islands of Aruba, Bonaire and Curacao lie off the coast of Venezuela and just on the edge of the Caribbean hurricane belt. They are the most arid islands in the region all year and see only slight increases of rain during the hurricane season.

But August is the end of their normal dry season. On average, their rainfall increases from about one to two inches each month during most of the year to about three inches in September, October and November, according to Netherland Antilles Meteorology.

Several other destinations average about four inches of rain in August and also may have lower risk. They include Antigua, Cancun, Montego Bay, Punta Cana and St. Maarten.

Islands with a higher than normal risk of rain include Bahamas, Dominica and Martinique. Total rainfall in the Bahamas jumps by 50 percent versus July.

The popular Central American destinations of Belize and Costa Rica, which are famous for their rainforests, usually see high levels of rain as well.

Caribbean Temperatures in August

Staying warm in the Caribbean isn’t a problem in August. Places such as Cancun, Cayman Islands, Cozumel, Aruba and Curacao all see average high temperatures exceed 90 degrees Fahrenheit on many days.

Anyone who has visited those locations in the summer know that the heat can be unbearable at times, especially inland or walking on beach sand in the middle of the afternoon. Aruba and Curacao in particular have arid interiors with little to no shade. Visitors should try to do any shore excursions on land in the mornings when temperatures are lower.

Locations with more moderate temperatures include Antigua, St. Lucia and Dominican Republic.

Cruise Weather in August

Higher rainfall and hot temperatures make western Caribbean cruises less appealing in August for Cancun, Cozumel, Grand Cayman and the Central American countries.

Eastern cruises are only slightly better, but travelers should avoid the Bahamas because of much higher than normal rainfall. San Juan and St. Lucia also have wet months.

Southern Caribbean weather makes cruises there a better choice, especially for ones that visit the dry islands of Aruba and Curacao.

Anyone who wants to take a Caribbean cruise during the summer and has some flexibility with their schedules may want to cruise during July and especially during June. The average rainfall is lower for most destinations.

But at least August is better than September. Historically, September is the worst month of the year for rain, storms and hurricanes in the Caribbean.
