Sydney Diving Conditions – 23 May 2026
Updated Daily by Local Experts
Today is a protected-site diving day around Sydney. The open coast is carrying a strong easterly swell with enough size and period to create heavy surge, messy entries and reduced visibility at most ocean-facing sites. Camp Cove, Lilli Pilli and Ship Rock near high slack are the most sensible options. Bare Island may be workable only on the most protected side for experienced local divers, but it is not a relaxed first pick today.
Conditions at a Glance
Weather: Cloudy with a high chance of showers, most likely this afternoon and evening. Winds S–SW 15–20 km/h tending S–SE during the morning, easing later.
Air Temperature: 21°C
Water Temperature: 19°C
Visibility: 3–5 m
Swell: 1.6 m E @ 10.4 s, with larger exposed-coast wave energy expected
Tides: Low 8:20 am 0.36 m; High 2:31 pm 1.24 m
Recommended Sites: Camp Cove — best protected option from today’s ocean swell; Lilli Pilli — highly protected fallback when ocean sites are too rough.
Detailed Report
The main issue today is easterly swell wrapping into the Sydney coast. Even where the wind is not extreme, the swell has enough size and period to make exposed rock entries uncomfortable. Expect surge across shallow reefs, poor holding on exposed platforms, and stirred-up water on the open coast.
Visibility is likely to sit around 3–5 m at ocean sites. Rain is in the forecast, but runoff is not the main concern at this stage. The bigger visibility problem is swell energy moving sand, kelp and suspended particles around shallow ledges. Keep navigation simple and avoid overcommitting to exposed areas in low visibility.
Bare Island is only a cautious ocean option today. The headland gives some protection from easterly energy, but the swell is still large enough to wrap into the island and make the exposed corners uncomfortable. If you dive it, use the most protected eastern side, watch several sets before entering, and be ready to relocate if the entry is washing through.
Ship Rock is one of the better choices if you can dive close to the 2:31 pm high slack tide. Tide matters more than swell there, and the high slack window will give the easiest current and navigation. Camp Cove, Shelly Beach and Lilli Pilli are the better protected options for divers wanting a calmer shore dive.
Boat diving is likely to be affected by the sea state. Exposed offshore reefs such as Magic Point, Barrens Hut, Osborne Shoals and deeper offshore sites will be uncomfortable in the easterly swell. If any boat diving runs, it should be conservative and aimed at experienced divers only.
Water temperature is 19°C. A 5 mm wetsuit is workable, but a hood or vest will make a noticeable difference on longer dives. Take a torch for the low visibility and keep the dive plan simple.
Safety: Do not judge today by wind alone. The swell is the problem. Choose protected entries, avoid exposed platforms, and be ready to move the dive if surge is stronger than expected.
Dive Tips for Today
- Choose Camp Cove, Lilli Pilli, Shelly Beach or Ship Rock near high slack for the easiest diving.
- Use Bare Island only if the protected eastern entry looks manageable.
- Avoid Oak Park, The Leap, Leap to Steps and Voodoo.
- Expect 3–5 m visibility and active surge on open-coast sites.
- Keep plans conservative and avoid shallow surge zones.
Safe dives and happy bubbles!
Weekend Dive Forecast
Saturday: Saturday is marginal to poor for exposed shore dives. The easterly swell around 1.6 m at 10.4 s will create surge at Bare Island, Oak Park, Kurnell and other open coast entries. Visibility is likely to stay low to moderate. Protected shore sites are the best option. Boat diving is likely to be affected by sea state, especially on exposed offshore reefs.
Sunday: Sunday looks more difficult, with swell building to around 1.8 m E at 12.1 s. The longer period will add more push underwater and make exposed entries harder. Expect a stronger surge at Bare Island, Oak Park and exposed Kurnell sites. Very protected shore sites should remain the best option, while boat diving should be treated as marginal unless conditions improve on the day.

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.
