Seasons and weather
Fajardo is warm and tropical all year, typically in the 80s Fahrenheit, with brief passing showers possible in any month. December through April is the peak visitor season: drier, busier, and pricier. Summer is the hottest stretch and busy with local travelers, especially around the beaches. Winter brings stronger trade winds and choppier seas, while late spring and summer tend to offer the calmest water for trips out to the cays.
Hurricane season
The Atlantic hurricane season runs June 1 to November 30, with peak activity from August to October. This does not mean constant storms, and plenty of trips in those months go perfectly, but it is sensible to watch forecasts as you travel and to consider travel insurance. Brief disruptions, rather than direct hits, are the more common reality.
Timing the bioluminescent bay
For the bioluminescent bay, the calendar that matters is the lunar one, not the seasonal one. The glow is faint, so it reads strongest on dark nights around a new moon and weakest on the bright nights near a full moon. If the bay is the centerpiece of your trip, pick your dates around a new moon and check a moon calendar before you book. Our email list also flags the best upcoming bio-bay nights.
Crowds and timing
Weekends, holidays, and summer are the busiest times at the beaches, the bio-bay launch area, and the Ceiba ferry. Weekdays are noticeably calmer, and arriving early in the day takes the pressure off parking and crowds at the popular spots. For the logistics of getting here, see getting to Fajardo.
