AccessBlack Rock is a shore entry beside a busy resort beach. Use the marked public access and enter only when the shore break is small.

ParkingResort and public parking rules differ. Confirm the public lot or access route and do not use hotel spaces without permission.

ReservationsShore snorkeling does not use one general reservation. Boat trips and equipment rentals have their own booking rules.

ClosuresSkip the entry when shore break, surge, or a posted warning makes the rocks hard to read.

Marine lifeReef fish and turtles may pass the point. Keep space from animals and never climb onto the reef.

Jellyfish drift risk

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

Low · 34/100

Low peak drift risk around Tue 09:00.

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.
