Cool and Popular
January, February and March are dry times in the Caribbean with most destinations averaging about two to three inches of rain. Daytime temperatures are warm, but nighttime temperatures are much cooler than normal.
Ocean currents from the north will bring cooler waters south and sometimes make water uncomfortable for swimming. Southern destinations such as Aruba have the warmest water.
Because of this dry season, western Caribbean cruises in particular jump up. March often sees a spike in vacations because of families and college students going on spring break.
