Average Caribbean Weather

Caribbean weather has average daytime temperatures ranging from the low 80s Fahrenheit and high 20s Celsius in the winter to the high 80s Fahrenheit and low 30s Celsius in the summer. The dry season goes from December to May. The hurricane season with a higher risk of rain lasts from June through November.

Following is a summary of average Caribbean weather by month. Click on the links for average rainfall and temperatures by month for every major destination.

Caribbean Weather in June

June is the start of the Caribbean hurricane season. Although hurricanes are rare, the average rainfall climbs for many Caribbean islands. Warmer temperatures make a cruise or beach vacation more appealing despite the higher risk of rain.

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 in the western Caribbean have high levels of rain, but heavy rainfall is normal.

Better vacation destinations are in the southern and eastern Caribbean. 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.

July

Cozumel beaches are hot in July when temperatures often go above 90 degrees Fahrenheit.

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.

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.

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 Curaçao.

September

Three types of people visit the Caribbean in September:

People who don't know that September is the worst weather month.

People who do know but take a chance anyway.

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 in the southern Caribbean still is the leader for the lowest risk of rain, followed by nearby Curaçao. 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.

October

Visitors in October may hope for better weather than September, which historically has the worst Caribbean weather of the year. But they might not get it. October is the second worst month of the hurricane season with a historical average of three hurricanes.

Aruba and Curaçao historically 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.

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

November

The western Caribbean island of Grand Cayman is popular in the winter, thanks in part to Seven Mile Beach.

It's tempting to breathe a sigh of relief in November, which is the final month of the Caribbean hurricane season.

Caribbean weather in November historically averages no hurricanes and only one tropical storm every other year. But rainfall is higher than average for nearly all islands in the region, especially the popular cruise ports at Barbados, Grand Cayman, St. Lucia, St. Maarten and St. Thomas.

Temperatures stay in the mid to upper 80s Fahrenheit for most destinations. Cruise and resort visitors won't have a problem staying warm.

December

Our second eastern Caribbean cruise in December had fantastic weather with temperatures in the low 90s Fahrenheit and almost no rain. But we had good luck. It was warmer and drier than usual.

Temperatures are normally in the mid 80s Fahrenheit for most destinations. Rainfall averages about three to four inches during the month, which is slightly above average.

December is a popular month for Caribbean vacations because of better weather than the previous four to five months. People also flock here from northern destinations to get away from winter cold and snow.

The better options for weather include Antigua, Aruba, Grand Cayman and the Virgin Islands because they have lower risk of rain. Cancun, Cozumel, Jamaica and San Juan are usually still a bit wet. The Bahamas are dry but cooler. Keep in mind that these historical averages may vary from year to year. See more about December weather.

January

The Caribbean in January offers a warm escape from cold northern winters. Most major destinations have an average high temperature in the mid 80s Fahrenheit or high 20s Celsius. Low rainfall is common because the region is starting the annual dry season.

Yes, daytime temperatures are usually warm for most destinations. But nighttime temperatures are cool enough to bring down water temperatures during the night. They become uncomfortable for swimming at times. My advice: click on the January link to see temperature charts for every major destination and choose the warmest. Western Caribbean weather is ideal during these winter months.

February

My trips to the Caribbean in February have taught me to expect some of the lowest rain of the year but also some of the coolest water temperatures.

I suggest planning on shopping, shore excursions and other land activities in the mornings until temperatures get warmer. Then hit the beach in the early to mid afternoon for the warmest land and water temperatures of the day.

Our February weather guide has average temperatures for every major destination.

March

March weather in the Caribbean is nearly ideal for a combination of warm temperatures and low risk of rain. Average high temperatures hover around 85 degrees Fahrenheit or 29 Celsius for many major destinations. Although April is even better, Caribbean tourism jumps in March because of families on spring break from schools.

Western Caribbean cruises are popular during this month. Beware spring break for many schools and colleges that will flood some destinations with families and college students. Cancun in particular may get busy.

March weather also offers one of the driest months of the year for the Caribbean. Many islands have two inches of rain or less for the entire month.

April

Great weather arrives in the Caribbean. In my experience, April has the best weather in the Caribbean for any month of the year.

Temperatures have warmed to the point where swimming is usually comfortable even in northern destinations. It's near the end of the dry season, so most islands have low risk of rain.

The Bahamas may still feel a bit cool, especially in the water. Otherwise, most of the major Caribbean cruise ports will usually offer a good combination of warmth and dry weather.

May

Yes, the Caribbean in May is warmer than April, but it also brings a brief rainy season to some destinations.

They include the Bahamas, Cancun, Cozumel, Grand Cayman and Jamaica. It's a better time of year for eastern or southern Caribbean cruises. It is not a good time for western Caribbean cruises which have a lower risk of rain from January through April.
