Average Caribbean temperatures vary little in the southern and western regions, but they vary quite a bit in the east.

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 even more north of the Bahamas.

A few destinations are worth noting.

  • Bahamas. The islands are located east to southeast of Florida, are not technically part of the Caribbean but often are the first stop of many eastern Caribbean cruises.
  • Bermuda. This British overseas territory is actually located east of North Carolina.
  • Costa Rica. Temperatures are cooler in the mountainous interior and warmer on the coast.

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 resot 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.
