ParkingUse the public beach parking and follow resort access signs. Do not block the road or emergency lanes.

ReservationsNo general shore-snorkel reservation is listed. Rentals and guided trips may require separate booking.

ClosuresMove to a sheltered beach when wind, surge, or poor visibility makes the reef hard to read.

Marine lifeReef fish and turtles can be seen on calm days. Keep a hands-off distance from animals and coral.

Jellyfish drift risk

Drift estimate from wind, swell, current and warm water.

Low · 34/100

Low peak drift risk around Sun 16:00.

warm water supports seasonal jellyfish activity; surface drift/current is noticeable; local shoreline exposure is not mapped yet.

Sightings override the model: if you see small purple jellyfish with long trailing tentacles, treat them as sting-capable and give them space.

Scoring methodology (for technical users)

We score each hour from 0 to 1 using daylight and these weighted components:

  • Wave height (35%): best below 0.36m, then decreases as it rises.
  • Wind speed (25%): best below 5.4m/s, lower is better.
  • Sea surface temperature (15%): best within 20.6°C to 30.4°C.
  • Tide and currents (15%): best around slack/high-tide windows.
  • Daylight (10%): visibility is better in daylight, so night hours score lower.
