Best season for most travelers
June to October usually gives the safest combination of beach quality, resort comfort, and easier excursion planning.
Warm holiday season
December to February can work very well if you are comfortable with higher demand and want a warmer peak-travel atmosphere.
When to be more cautious
Rainier periods are less ideal if you want a smooth first trip centered around beach time and outdoor excursions.
