Average Caribbean temperatures for most destinations range from the low 80s Fahrenheit in the winter to the high 80s in the summer.

Some destinations get even hotter. Aruba, Cancun, Cozumel, Curacao, Grand Cayman and St. Thomas are the hottest destinations in the summer with daytime temperatures reaching into the low 90s Fahrenheit or low 30s Celsius.

The Bahamas, Roatán, Puerto Plata, Punta Cana and Turks and Caicos have the coldest daytime temperatures during the winter. They average around 80 degrees Fahrenheit or 27 Celsius.

The eastern region usually includes the Bahamas for the sake of eastern Caribbean cruises, even though the Bahamas aren’t actually located in the Caribbean Sea. But they share a great deal with the rest of the Caribbean. The same is true of Bermuda, which lies north of the Bahamas. But it is much colder and isn’t a common beach destination in the winter.

The following list has the three best Caribbean destinations for warm weather by month. These average temperatures come from historical data from the meteorological services of each location. Actual temperatures in the current or upcoming year may vary from the historical averages.

It is important to keep in mind that some of the warmest destinations also have some of the highest rainfall during that time of year. It is especially true during the Caribbean hurricane season.

  • January: Grand Cayman, Aruba and Curaçao
  • February: Aruba, Grand Cayman and Curaçao
  • March: Cozumel, Aruba and Grand Cayman
  • April: Cozumel, Grand Cayman and Cancun, Aruba and Curaçao (tie)
  • May: Cozumel, Cancun and Grand Cayman
  • June: Cancun, Grand Cayman and Aruba and Cozumel (tie)
  • July: Cancun, Grand Cayman and Cozumel and St. Thomas (tie)
  • August: Cancun, Grand Cayman and Aruba, Curaçao and St. Thomas (tie)
  • September: Aruba, Grand Cayman and Cancun, Curaçao and St. Thomas (tie)
  • October: Grand Cayman, Aruba and Curaçao and St. Thomas (tie)
  • November: Aruba, Grand Cayman and Curaçao
  • December: Aruba, Grand Cayman and Curaçao

Temperatures in the southern Caribbean are slightly warmer during the winter, which is why Aruba, Barbados, Curacao and other nearby islands are popular during that time of year.

Water Temperatures

Water temperatures average about midway between the high and low temperatures of the day.

They typically will be about three to five degrees cooler than the air temperature and reach their high point around early to mid afternoon.

Southern destinations will have the warmest water temperatures year round because they are closest to the equator.

Trade Winds

Trade winds create a wind chill factor in the Caribbean like everywhere else. The winds are strongest coming from the east.

As a result, it is wise to consider staying in a hotel, villa or resort on the eastern side of a destination during the summer and the western side during the winter if the winter location is cooler than most.

10-Day Weather Forecasts | See Caribbean monthly weather in: January - February - March - April - May - June - July - August - September - October - November - December

January, February, March

Air temperatures stay flat for the first three months of the year for most islands. One exception is Cozumel, which climbs from 83 Fahrenheit in January to 78 in March.

Aruba, Curacao, Cozumel and Grand Cayman are among the hottest. The Bahamas, San Juan and Dominican Republic are often too cold for swimming.

April, May, June

This is the ideal time of year to visit the Caribbean for anyone who likes warm weather, comfortable swimming and low risk of rain.

Nearly every major destination has daytime temperatures in the upper 80s Fahrenheit. By June, the hottest islands average 90 degrees Fahrenheit or 32 Celsius. They again include Aruba, Cancun, Cozumel, Curacao and Grand Cayman.

July, August, September

Temperatures increase again for all islands, but the summer is the start of the Caribbean hurricane season.

Vacation planners who love beaches should plan to go as early as possible in the summer because hurricane and tropical storm activity start increasing and reach a peak in September and October. Tourism dives during those two months.

October holds onto hot temperatures that make Caribbean beaches inviting. But it is the second most active month of hurricane season after September.

The official hurricane season ends on Nov. 30, while temperatures beginning dropping toward the lows of the year in December.

December is one of the most popular months to visit the Caribbean for northerns seeking to escape winter. It also is one of the coldest months of the year in the Caribbean.

Still, daytime highs remain in the upper 80s Fahrenheit for the hotter destinations such as Aruba, Curacao, Grand Cayman and St. Thomas. Meanwhile, the hot summer destinations of Cancun and Cozumel have average daytime temperatures that drop back down into the lower 80s Fahrenheit.
