Sydney Diving Conditions – 24 May 2026

Updated Daily by Local Experts

Today is a poor day for exposed ocean diving around Sydney. A large easterly swell with a 12-second period is producing strong surge, difficult entries and low visibility across most open-coast sites. The best options are protected shore dives such as Camp Cove and Shelly Beach, with Lilli Pilli also a sensible fallback. Bare Island is borderline and should only be considered by experienced local divers after checking the protected entry carefully.

Conditions at a Glance

• Weather: Partly cloudy with patchy morning fog and a medium chance of showers from late morning. Easterly winds around 18–28 km/h easing lighter early.
• Air Temperature: 21°C
• Water Temperature: 19°C
• Visibility: 2–5 m
• Swell: 1.8 m E @ 12 s, with powerful surf on exposed coastlines
• Tides: Low 9:12 am 0.40 m; High 3:30 pm 1.30 m
• Recommended Sites: Camp Cove — best protected option from today’s easterly swell; Shelly Beach — sheltered fallback when southern ocean sites are unsuitable.

Detailed Report

The key issue today is the easterly swell. At 1.8 m with a 12-second period, it has enough power to wrap into exposed southern sites and push strong surge through shallow reefs, ledges and rock-platform entries. Even sites that look manageable between sets may feel much stronger underwater.

Visibility is variable, around 2–5 m. Recent rain and runoff are starting to affect clarity, and the swell is stirring up suspended sand and kelp on the open coast. Expect green water, lower contrast and more difficult navigation at exposed ocean sites.

Camp Cove is the best practical recommendation today. It sits well inside the harbour and avoids the worst of the easterly ocean swell, making it a better choice for divers wanting a calm, straightforward shore dive. Shelly Beach is also a useful fallback, although visibility may still be affected by rain and stirred-up water.

Lilli Pilli is another protected option, especially for divers wanting to stay south. It is inside Port Hacking and much less exposed to the ocean swell, though visibility is usually lower than open-ocean sites. Ship Rock may be considered close to the 3:30 pm high slack tide, but only if current and visibility are suitable on arrival.

Bare Island is borderline today. The island has some protection from easterly swell, but the size and period mean surge can still wrap into the entries and shallow sections. It is not a relaxed first recommendation. Oak Park, The Steps, The Leap, Leap to Steps and Voodoo should all be avoided today.

Boat diving is likely to be affected by the large and powerful surf conditions. Winds are not the main problem; the sea state is. Exposed boat dives and offshore reefs are poor choices today, and boat operations may be cancelled rather than relocated.

Water temperature is 19°C. A 5 mm wetsuit is workable, but a hood or vest is recommended for comfort. Take a torch for low visibility and keep the dive plan simple, shallow and protected.

Safety: This is not a day for exposed ocean entries. Choose protected sites, avoid rock platforms with wash-through, and relocate early if the entry or exit looks uncomfortable.

Dive Tips for Today

• Choose Camp Cove, Shelly Beach or Lilli Pilli for the calmest shore diving.
• Only consider Ship Rock close to the 3:30 pm high slack tide.
• Treat Bare Island as borderline and check the protected entry before gearing up.
• Avoid Oak Park, The Leap, Leap to Steps, Voodoo, and exposed Kurnell entries.
• Expect 2–5 m visibility and strong surge at ocean-facing sites.

Safe dives and happy bubbles!

How Conditions Affect Dive Sites

Understanding Water Visibility in Sydney

What affects water visibility in Sydney?

Water visibility is influenced by tides, swell direction, weather, and even seasonal algae blooms. After rain or storms, visibility tends to drop due to sediment stirred up in the water.

How do tides impact visibility?

Slack high tide often provides the best visibility, as water movement slows and particles settle. Many Sydney sites are clearest just before high tide.

What’s the typical visibility range?

Visibility usually ranges from 5m to 10m but can exceed 20m in winter or drop below 2m after several days of heavy rain. July to October offers the clearest conditions.

Where are the best spots for good vis?

Sites like Shelly Beach, Bare Island (east side), and Ship Rock are known for consistent visibility—especially during high tide with minimal swell.
