Plan your visit

These notes help with planning. Rules and closures can change.

Open map

AccessShore entry is over lava rock and the cove changes quickly with swell. Treat winter North Shore surf as a no-entry signal.

ParkingParking fills quickly on the North Shore. Use legal spaces and keep emergency access clear.

ReservationsNo general snorkel reservation is listed. Check posted rules and current surf notices.

ClosuresDo not enter during large surf, strong surge, or a posted closure. Summer conditions are usually the more practical window.

Marine lifeSharks Cove sits in the Pupukea Marine Life Conservation District. Do not take fish, coral, rocks, or shells.

Jellyfish drift risk

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

Low · 34/100

Low peak drift risk around Sat 08:00.

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.
