Cateran Bay (North Border Island)

Moderate risk: Wind bullets in strong winds

Southerly and south-easterly winds can create 'bullets' (strong, gusty winds funnelling down from the hills) that affect the anchorage and water conditions.

Moderate risk: Wind bullets in strong northerlies

In strong northerly winds, 'bullets' (strong, gusty katabatic winds) can sweep down off the hills, creating sudden squalls in the anchorage.

Moderate risk: Strong tidal currents at bay entrance

Strong currents can develop at the entrance to Cateran Bay, particularly at the northwest tip of Border Island.

Low risk: Tidal currents

Strong tidal flows can sweep through the anchorage, especially during spring tides, requiring caution when entering and exiting the water.

Low risk: Tidal beach access

The beach is only accessible at mid to high tide — at low tide the sandy shore is largely submerged, limiting landing options.

Low risk: Marine park restrictions (Green Zone)

The area is a Green Zone (no-take marine park) — fishing is prohibited, and all marine life must not be disturbed.

Low risk: Tide-dependent beach access

The beach is only accessible at mid to high tide; at low tide the sand is submerged or very narrow, making landing difficult.

Low risk: Outgoing tide current

Outgoing tidal currents can be strong through the channel between Border Island and surrounding reefs, challenging weaker swimmers.

Low risk: Submerged coral heads near moorings

Isolated submerged coral heads in the mooring pickup area pose a collision risk for vessels and swimmers.

Low risk: Tidal access limitations

The beach at Cateran Bay is best accessed at mid to high tide; at low tide the beach area is reduced and coral may be exposed.
