Air and ocean temperatures are usually cooler in the winter season, and warmer during summer. Even during the rainy season the temperature remains warm.
Many people think that in rainy season it rains all day.
Typically, it is sunny most of the day with heavy clouds developing in late afternoon, followed a few hours later by two or three hours of sometimes heavy downpour. Usually by 10 or 11 PM the rain and clouds are gone. Don't worry about hurricanes.
