Do You Prefer Sunshine or Hurricanes?

Weather in the Caribbean can give visitors a beautiful experience or a disaster that is best forgotten. The average weather shows both the best and worst times to go.

Caribbean daytime temperatures stay in the mid-80s Fahrenheit for most destinations. This average varies by only a few degrees each month. But nothing is average or predictable about the rainfall.

Cruise and resort visitors to the Caribbean who want the most sunshine and lower the risk of rain should first understand the impact of the annual hurricane season. It officially runs from June 1 through November 30 each year.

6 Quick Climate Tips

  1. Aruba, Bonaire, and Curaçao have the least rain yearround.
  2. April, June, and July have the best combination of warm temperatures and low rainfall.
  3. May brings with it a brief rainy season in many places.
  4. September and October are the worst months to go because they have the highest risk of tropical storms or hurricanes.
  5. From December through February, stick with southern destinations such as Antigua, Barbados, and St. Lucia.
  6. The best months to visit almost any island for low risk of rain is January through April.

The following Caribbean weather tips and statistics are based on my 15+ trips to the Caribbean plus extensive research from the U.S. National Weather Service.

Best Times to Visit the Caribbean

The risk of rain for most islands in the Caribbean is January through April, but average temperatures are lower as well.

Seawater is often cool for swimming in January and February, especially in the mornings. So those months are ideal for people who like land activities and excursions.

Sometimes the water are too cool for any time of day. During our visits to Aruba and Cancun in February, no one got in the water for more than a few minutes because of chilly water and even chillier trade winds. But water that chilly isn't common in the winter.

Tourists who like water activities such as swimming, snorkeling and laying on beaches instead may want to go in March and April for warmer temperatures.

Although May is even warmer than April, it also has a higher risk of rain for some destinations. For example, historical data shows that Grand Cayman averages two inches of rain in April but six inches in May, according to the National Meteorological Service of the Cayman Islands.

Then the Caribbean hurricane season begins in June.

High, Low and Value Seasons

Caribbean destinations have high, low and value seasons that are largely based on weather and best and worst times to go.

A book such as Essential Caribbean by Fodor's Travel (which I own and have read) has extra details on each one of these seasons for every destination in the When to Go sections. They also have Big Events that impact the three travel seasons.

Although each destination is somewhat different, in general, the high season is winter and spring and is the most expensive time to visit. Low season is the hot months of late summer. The less expensive value season is late spring to early summer and again from late fall to early winter. Essential Caribbean has details by month.

Hurricane Season

The Caribbean is known for a rainy season that brings tropical storms and hurricanes. Some islands can get hit especially hard with rain and heavy winds.

The season starts slowly in June, builds over early summer, and doesn't peak until September and October. The storm and hurricane threat is why the fewest number of people vacation in the Caribbean in October and especially September.

During late spring, summer, and fall, tropical storms often form in the Atlantic, off the African continent, and move west toward the Caribbean.

As they approach the Americas, they tend to swerve to the right, and follow various paths over the Caribbean or the Gulf, often reaching the Eastern US and even Canada or Europe.

Historical Paths of Atlantic Hurricanes

Once formed, a storm moving over warm water can grow into a hurricane in a matter of days.

On the average (some years are much more productive) the Caribbean hurricane season has about 12 to 15 major storms each year, and about four or five develop into hurricanes.

A hurricane can drop back in intensity to a storm again for a few days before fading away.

Tropical weather in the Atlantic is closely watched, and Caribbean weather forecasts are fairly reliable because the weather follows a predictable set of patterns.

Average Caribbean Weather By Month


Caribbean weather in January is certainly warmer than the U.S., Canada, or Europe, but some places are warmer than others. The warmest destinations include Cayman Islands and St. Lucia; the coolest include the Bahamas, Dominican Republic, and Turks and Caicos. Rain averages about two to three inches per month. Keep in mind that sea temperatures is often cool for swimming in northern locations.


Temperatures in February show little movement. In some places they increase a degree while in others they decline. In Dominica, rainfall increases to four inches. Costa Rica reaches a low point for rain, which is good news for western Caribbean cruises.


March is one of the most popular months for visiting the Caribbean, not just because of spring break, but because of warming temperatures and low rainfall for many destinations. In Dominica, rainfall climbs again to five inches, but keep in mind that Dominica is a lush island with waterfalls and tropical rainforests. It's a great place for ecotourism, though not so much for lying on a beach. Costa Rica continues to have low rainfall.


April is another great month to visit the Caribbean, for the same reasons as March, but with some exceptions. In San Juan, Puerto Rico, rainfall reaches its first high point of the year at six inches. It's not the best time for a long-term stay, but it's okay for cruise visitors, who can visit indoors San Juan historical sites and shopping.


Caribbean weather in May includes a brief rainy season for many destinations. Aruba is a safe bet because it is the driest island of all. Rainfall at Cancun, Cayman Islands, Costa Rica, and Dominica jumps to five inches or more per month.


This is a bad month for the Bahamas, with an average of nine inches of rain. Cozumel gets eight inches, while Belize and Costa Rica average more than 10. For people who like hot weather, Cancun, Cayman Islands, and Cozumel have average high temperatures that reach 90 degrees Fahrenheit.

June is the official beginning of the annual Caribbean hurricane season. But historically it almost no hurricanes and only one tropical storm every other year, according to the U.S. National Hurricane Center.

Hurricane season is starting to make itself known, with six inches or more of rainfall for the Bahamas, Barbados, the Cayman Islands, and St. Lucia. It's a good month for Antigua, Cancun, the Dominican Republic, Jamaica, and the U.S. Virgin Islands. July averages three tropical storms with two that become hurricanes.


"Ugh" is a good word to describe rainfall for the Bahamas and Cancun. Every major destination except for the ABC islands of Aruba, Bonaire, and Curaçao averages four inches or more. On average, August has three tropical storms with two that become hurricanes.


September is the worst month of the year for Caribbean weather because it’s the worst month of the annual hurricane season. An average of four tropical storms occur in September with two that become hurricanes. Avoid Caribbean destinations, except possibly the ABC islands—Aruba, Bonaire, Curacao—and maybe the Dominican Republic. But at least September is warm.


October is barely better than September, usually the second worst month of the year for Caribbean weather. All of the major destinations average five inches or more of rain. On average, four tropical storms develop, but they rarely grow into hurricanes.


The Bahamas finally get a break from the rain and wind, but the temperatures are starting to drop too. Barbados, Cancun, and Jamaica are becoming better options. St. Maarten has the heaviest rain of the year. On average, only one tropical storm forms every other year. Hurricanes are rare.


The hurricane season is officially over and rainfall declines everywhere. But temperatures are declining as well; the Bahamas, Cancun, and other northern destinations are usually too chilly for swimming. Dominican Republic and St. Thomas are worthy options. Tourist activity starts to increase in the Caribbean as northerners start to flee cold winter weather.

Caribbean Temperatures By Month

What most people consider the Caribbean ranges from the Bahamas in the north to Aruba, Barbados and Trinidad in the south. The total distance is more than 1,000 miles.

Average Caribbean temperatures in the daytime usually are in the mid to upper 80s Fahrenheit for most destinations throughout the year, except for the Bahamas, which fall into the 70s during the winter.

A few locations such as Cozumel and Grand Cayman see average highs above 90 during the summer.

Nighttime lows drop into the mid to upper 70s. Winter daytime air temperatures stay warm in most places. But winter water temperatures become a bit uncomfortable in places such as Cancun.

How Weather Affects Cruises and Stopovers

Climate in the Caribbean may pose less of a problem for cruise visitors than for stopover visitors.

Ships can steer away from bad weather, although they may not avoid it entirely. At least cruise staff can deal with rough seas. Passengers can wear motion-sickness patches and adjust their diet to settle upset stomachs.

People who plan a cruise will find it useful to consider the following weather tips:

  • Late spring to mid-summer has the best Caribbean cruise weather, but it's also the most popular time to go.
  • Winter is a good time for southern destinations such as Aruba, Bonaire, and Curacao.
  • The western Caribbean is rainy in early fall, especially in Cozumel and the Central American nations that line the Caribbean coast.
  • In the eastern Caribbean, weather is cool during the winter in northern destinations such as the Bahamas.
  • Stopover visitors—people who stay on an island for a week or so—face a greater risk of a tropical storm or even a full-fledged hurricane making landfall. Vacationers can’t really predict the weather a week in advance; two or three days out is more realistic.

No destination is particularly likely to lie right in the path of disaster from a storm or hurricane. But storms and hurricanes that pass through the region affect islands and coastlines over large areas. A tropical storm can dump large amounts of rain even at its outer edges.

One way to avoid getting entangled in a tropical storm is simply to stay away from the Caribbean, and especially the islands most likely to be hit, during September and October in particular. Another way of preparing for the possibility is to buy travel insurance.

Questions & Answers

  • I'm going to be cruising the Caribbean on September 24th for a week down to Haiti and Mexico, will we be hit by a hurricane?

    September is the worst month of the year for rain and hurricanes in the Caribbean. It also has some of the cheapest cruise prices as a result.

    That said, cruise ships avoid hurricanes. Out of the four hurricanes that the Caribbean averages in September, the odds are extremely low that any of them will pass near your ship.

    You might also get lucky and go during a week when there are no hurricanes or tropical storms. You are more likely to experience an increase in rain and cloud cover.

  • I am cruising Cozumel, Belize, Roatan, and Grand Cayman from October 28th to November 5th. What kind of weather and temperatures should we expect?

    November is the final month of the Caribbean hurricane season. Fortunately, it's one of the least active months for hurricanes and tropical storms.

    If I were you, I would go expecting at least some rain and clouds. But I would cross my fingers and hope that good luck brings me good weather.

      I am thinking about moving to Caribbean, I am Swedish. Is it bad to live in a Caribbean island that can get affected by tropical storms and hurricanes? Are there any caribbean islands that don't suffer a lot from tropical storms and hurricanes? Do you recomend choose island based on how affected they are by storms or how should I think? Thank you for any advice.

      Hi, Sonya. You'll have to do a little trading with the weather. April is one of the best months of the year to visit the Caribbean for a combination of warm weather and low risk of rain.

      Miami also has a low risk of rain in April, but temperatures are cooler and may feel a bit chilly for swimming, especially in the mornings. The Miami rainy season goes from June through September.

      So if you are big on swimming and snorkeling, I recommend April to early May.

      Hi, Cynthia. I hate to discourage you, but the odds are high that the water will feel too chilly for swimming.

      The nighttime temperatures in the Bahamas average in the low 60s Fahrenheit in January and February. And then there is the wind chill factor. Water temperatures usually hover around the mid point between the daily highs and daily lows.

      So water temperatures during the day will probably be in the low 70s, which is below the recommended comfort zone by experts.

      You might get lucky and go there during a warm spell. But if you love the water, you are better off going farther south in the Caribbean. Aruba has better odds of weather warm enough for swimming.

      Hi Scott- I am looking at booking Exuma for my family the week after Christmas through New Years. We love to boat and be in the water. We love warm water too. The air temp that time of year is recorded to be high 70's. Is the water too cold that time of year and are there winter winds and storms that frequent that area? I know you take a chance when you don't go further south but Exuma has great direct flights. It will be my husband and I's 25th wedding anniversary and we want to have a great time with the kids. Thanks!

      Hi, Keith. Bahamas weather in May is a transition month between the dry season -- which goes from December through April -- and the rainy season which hits in June.

      I suggest going as early possible in May. On a personal note, we visited in May one year and had rain all week. So there are no guarantees. But going earlier in the month lowers the risk. Good luck!

      Hi, Kaziopeia. I don't often get questions about Grenada!

      Grenada's average monthly weather is like quite a few other islands in the Caribbean. The average daytime temperatures hover in the mid 80s Fahrenheit. Rainfall is usually moderate from February through May and then picks up for the rest of the year.

      Jay, they actually do feel the effects of storms and hurricanes, but to your point not nearly as much as other islands. Their average rainfall spikes from October through December during the end of the hurricane season.

      They also have increased cloud coverage during the hurricane season, which I have seen during my 4 trips to Aruba.

      No destination is particularly likely to lie right in the path of the disaster from a storm or hurricane. That statement is not totally true since Aruba Bonaire, and Curacao are too far south to receive any effects of hurricanes. In addition, Venezuelan mountains block any sort of depression coming from the Atlantic ocean leaving the islands in a dry condition and storm-free year-round.

      Hi, Mary. I can predict with a fair amount of confidence that the daytime temperature in Barbados during October will be in the upper 80s Fahrenheit. But I can't predict with any confidence whether you will have rain. Sorry.

      Hello, JS. The islands with the lowest risk of rain in September are Aruba and Curacao. Barbados averages twice as much rain that month than the other two.

      I can't promise you will have great weather in either Aruba or Curacao, but the odds are better than Barbados. Good luck with your trip!

      For schedule reasons, I can only go to the Caribbean in September (I know, the worst month to visit!)

      In you experience, which Island would be the less hurricane risky/rainy to go in the middle of September. I was thinking Barbados.

      I am going with my wife and a baby.

      Thank you again for your advice. Your article is very helpful!

      Hi, Emma. I'm sorry to hear you couldn't find a hotel in Aruba to meet your needs. Aruba has the lowest risk of rain in June along with great beaches.

      The next best option for low risk of rain is Curacao, but it doesn't have as many hotel options as Aruba or beaches as good. The same with Antigua and St. Maarten.

      If you want all inclusive, you can try Puerto Plata in Dominican Republic, which usually doesn't get as much rain in June as other destinations.

      Congrats on the marriage and good luck with your honeymoon!

      Hi Scott. Great article thanks for sharing! We are planning our honeymoon for 24th May 2020 for 2 weeks so will take us into start of June. We want to go to a Carribean island but want to avoid anywhere which will have lots of rain, we know we’ll have some small rain periods but don’t want anything which will stop us sunbathing!! Ideally want warm temperature to go into the sea, sunshine and limited rain. I see you have mentioned Aruba which we did look at, but could not find a hotel which met all our needs (we like fairly modern and contemporary!), and the hotels in Aruba were beautiful but all a little dated. Which other islands would you recommend for that time of year?

      Thanks so much in advance!

      Hi, Mary. The odds of bad weather are higher than normal in September, but you won't be directly hit by a hurricane. Cruise ships will change course if necessary to avoid the worst weather.

      It helps to keep in mind that the Caribbean Sea is an area of more than 1 million square miles. So even if a hurricane comes to the Caribbean during the same week as your trip, the odds are good you won't be anywhere near it.

      With a little luck, there won't be a hurricane or tropical storm at all in the entire region during your cruise. Best of luck to you!
