October Weather Outlook


Hurricanes Irma and Maria delivered massive damage to the Caribbean in September. Visitors in October may hope for better weather, but they might not get it. October is the second worst month of the hurricane season with an average of three a month.

Aruba and Curacao historicall have the lowest rainfall during the month at three inches each, which is actually above normal for them. They are the islands to visit with the lowest risk of rain. St. Maarten ranks third, but it is still badly damaged by Irma.

Places to avoid with an average of eight or more inches of rain include Belize, Cancun, Cozumel, Dominica, Gaudeloupe, Grand Cayman and St. Lucia.

September


Three types of people visit the Caribbean in September:

  1. People who don't know that September is the worst weather month.
  2. People who do know but take a chance anyway.
  3. People who see a good 10-day weather forecast and book at the last minute.

Weather in the Caribbean during September is the worst of the year because it is the peak time of activity for the annual hurricane season. Historically, the region averages four tropical storms with three becoming hurricanes and two of them becoming major hurricanes.

The dry island of Aruba still is the leader for the lowest risk of rain, followed by nearby Curacao. Most other destinations average between six and 13 inches of rain. Daytime temperatures for most of them average in the upper 80s to low 90s Fahrenheit.

August


August weather is usually grim for the Bahamas. Historically, Nassau averages more than nine inches of rain during the month, according to the Bahamas Department of Meteorology. Anyone planning a Caribbean cruise might want to avoid the Bahamas.

Other destinations that average high levels of rain in August include Belize, Costa Rica, Dominica, Guadeloupe and Martinique. Islands with the lowest average rain are Aruba and Curacao.

Heat reaches the highest point of the year for many destinations. Average daytime temperatures often go above 90 degrees Fahrenheit or 32 Celsius for Cancun, Cayman Islands, Cozumel, Aruba and Curacao.

July


July weather in the Caribbean is more risky than June. The region averages three tropical storms during the month with two becoming hurricanes, according to the U.S. National Hurricane Center.

Average daytime high temperatures reach or go above about 90 degrees Fahrenheit or 32 Celsius for many major destinations. They include Aruba, Cancun, Cozumel, Curacao, Grand Cayman and St. Maarten.

Destinations with higher than normal levels of rain historically include the Bahamas, Grand Cayman and St. Lucia. Avoid the Bahamas as part of an eastern Caribbean cruise. Places with low risk of rain include Aruba, Curacao, Montego Bay and St. Maarten.

Early July is less risky than late July because the Caribbean hurricane season gradually gets worse as its gets closer to the peak months of September and October.

June

Caribbean weather in June is the start of hurricane season, but hurricanes are rare. Temperatures reach the upper 80s Fahrenheit and rainfall is above normal.

The Bahamas have the highest rainfall among major islands with an average of more than eight inches. Other destinations with higher than normal rainfall include Cancun, Cozumel and Grand Cayman.

Belize and Costa Rica have high levels of rain, but heavy rainfall is normal. Islands with moderate rainfall include Antigua, Aruba and St. Maarten.

Average daytime temperatures for all major islands rise above 85 degrees Fahrenheit or 29 Celsius. Temperatures at Cancun, Cozumel and Grand Cayman increase to more than 90 Fahrenheit or 32 Celsius.

Grand Cayman is popular in the winter, thanks in part to Seven Mile Beach.

Summer Weather


Average high temperatures spike above 90 degrees Fahrenheit during the summer for several popular destinations including Aruba, Cancun, Cozumel and the Cayman Islands.

June 1 is the official beginning of the Caribbean hurricane season, although June historically has few hurricanes or tropical storms. July sees an increase in activity, and it goes up even more in August.

Fall Weather


Clearly the worst time to go -- and least popular -- are the peak months of the Caribbean hurricane season in September and October.

September is the low point for Caribbean tourism because that month historically has the highest average rainfall and the most tropical storms and hurricanes.

Bad weather subsides a bit in October, but it still is the second worst month of the year for rain and the second most unpopular month for tourism.

Winter Weather


The Caribbean in December begins the dry season for many locations, especially in the western Caribbean.

As a result, western Caribbean cruises zoom in popularity as vacationers flock to the major ports of call in Grand Cayman, Jamaica, Roatan and Cozumel.

December through March is a popular time to travel in the Caribbean for low risk of rain and as an escape from northern winters, but it also has the lowest average temperatures of the year.

Tourism increases during March in particular because of spring break for many schools.

Destinations in the northern parts of the Caribbean will have cooler waters for swimming, but places closer to the equator will be comfortable.

Temperatures are moderate for the islands, which hit highs in the 90s during the summer, and the Central American countries don't have the drenching rains that hit later in the year.

Spring Weather


Eastern Caribbean islands are more popular during late spring and summer because they reach their ideal temperatures.

March is usually one of the most popular times of the year to visit the Caribbean.

The average rainfall is low during April, but many locations have a brief rainy season during May.
