Plan your visit

Open map

AccessCairns is a gateway. Green Island, Fitzroy Island and the outer reefs have their own wind and swell. Open those reports before you leave the harbour.

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 · 22/100

Low drift risk now.

water is warm enough for occasional jellyfish; 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.

Upcoming high tides

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.
