Open map

AccessPort Douglas boats usually run to Low Isles or the Agincourt ribbon reefs. Check those site forecasts; the town beach is not the reef.

ParkingParking and boat-harbour rules vary by operator and town. Use marked spaces and never block ramps or residents.

ReservationsMany of the best reefs here are boat-only. Book a permitted operator and ask about weather cancellations.

ClosuresWind, swell, and park rules can close a site even when the town beach looks calm. Check the official source before entering.

Marine lifeDo not touch, chase, or feed marine life. Stay off coral and follow local park rules.

Jellyfish drift risk

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

Low · 27/100

Low drift risk now.

warm water supports seasonal jellyfish activity; 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.
