South Broulee  Cave

Moderate risk: Sand spit tidal cut-off

The sand spit connecting Broulee Island to the mainland can be submerged at high tide, stranding snorkellers on the island.

Moderate risk: Cave disorientation risk

The cave is narrow and dark; inexperienced snorkellers can become disoriented. A torch is essential.

Low risk: Ocean swell

Southerly and easterly swells can create surf and strong surge around the island's exposed southern side.

Low risk: Wind chop

Afternoon sea breezes can create choppy conditions on the exposed sides of the island, reducing visibility.

Low risk: Rocky entry

Some entry points have uneven, barnacle-covered rocks; reef shoes recommended to avoid cuts.

Low risk: Marine stingers

Bluebottles and occasional box jellyfish may appear during warmer months after northeasterly winds.

Low risk: Easterly swell and wind

Swell and wind from the east can create choppy conditions and surge around the cave entrance, making entry and exit tricky.

Low risk: Variable visibility

Low visibility (down to 5 m) can occur after rough weather or rainfall, making it easy to lose orientation near the cave.

Low risk: Rocky shoreline entry

Entry/exit over rocks and gravel can be slippery and sharp. Dive boots or reef shoes strongly recommended.

Low risk: Cool water temperatures

Water temps drop to 13-14°C in winter. A 5mm wetsuit with hood is recommended year-round.

Low risk: Swell and surf break

Broulee Beach can experience shore break and easterly swells that create turbulent conditions near the entry point.

Low risk: Rocky reef and urchins

Submerged rocky ridges and crevices are home to sea urchins with sharp spines; wear booties or fins when entering over rocks.

Low risk: Wind chop on easterly breeze

Easterly and north-easterly winds can quickly chop the surface and reduce visibility, especially in the afternoon.
