Terrigal Beach (The Haven)

High risk: Blue-lined octopus

The highly venomous blue-lined octopus (Hapalochlaena fasciata) has been recorded in the seagrass beds. Do not touch any small octopus.

Moderate risk: Boat traffic at ramp

The boat ramp is busy with launching and retrieving vessels. Avoid entering directly in front of the ramp and stay vigilant.

Moderate risk: Reef surge in swell

When swells break across the outer reef, strong surge makes snorkeling unpleasant and unsafe. If surfers are on the reef break, skip the dive.

Moderate risk: Swell surge on outer reef

When swells break across the outer reef, strong surge makes snorkeling unpleasant and hazardous. A good rule: if surfers are on the reef break, skip the dive.

Moderate risk: Swell and surge on outer reef

When swells break across the outer reef, strong surge makes snorkeling unpleasant and potentially dangerous. If surfers are on the reef break, avoid entering.

Low risk: Reduced visibility after rain

When Terrigal Lagoon is opened to the sea after heavy rain, runoff reduces water clarity significantly.

Low risk: Mooring lines and boats

Mooring lines from anchored boats can be entanglement hazards. Snorkel around moored vessels with care.

Low risk: Boat traffic at boat ramp

The boat ramp is active with vessel launching and retrieval. Stay clear of the ramp channel.

Low risk: Moored boat congestion

The area underneath moored boats can be crowded; watch for swinging mooring lines.

Low risk: Surge on outer reef

When swells break across the outer reef, strong surge can make snorkeling unpleasant and potentially dangerous. General rule: if surfers are on the reef break, give it a miss.

Low risk: Lagoon outflow after rain

After periods of heavy rain, Terrigal Lagoon is opened to the sea, carrying runoff and reducing water visibility and quality. Avoid snorkeling during these times.

Low risk: Mooring lines and boat traffic

The Haven has many moored boats with lines that can entangle snorkelers. Watch out for vessels moving within the harbour.

Low risk: Terrigal Lagoon outflow after rain

After heavy rain the council opens Terrigal Lagoon to the sea, reducing visibility and water quality. Avoid snorkeling for a few days following significant rainfall.

Low risk: Moored boat mooring lines

Several boats moor in the haven; submerged mooring lines and anchors present entanglement hazards, especially in the seagrass and sand-flat areas.

Low risk: Swell across outer reef

When swells break across the outer reef, strong surge makes snorkeling uncomfortable and disorienting. Check conditions before entering.

Low risk: Terrigal Lagoon discharge after rain

After heavy rain, the council opens Terrigal Lagoon to the sea, flushing sediment and freshwater into the Haven, drastically reducing visibility.

Low risk: Boat traffic near ramp

The Haven has an active boat ramp — snorkelers should stay well clear of the launch lane and be aware of vessels coming and going.

Low risk: Mooring lines and submerged anchors

Several boat moorings dot the bay with anchor chains, ropes, and a known submerged anchor that can entangle swimmers.
