Sydney Diving Conditions – 4 June 2026
Updated Daily by Local Experts
Today is a good shore-diving day at protected southern sites, but a poor day for boat diving. The local swell is small at 0.7 m from the east, and visibility should sit around 6–8 m at the better ocean-flushed sites. The main issue is wind: strong westerly coastal winds will make offshore boat diving rough, while many shore entries south of the harbour should remain quite workable. Bare Island is the best all-round pick today, with The Steps and Sutherland Point also strong options.
Conditions at a Glance
Weather: Partly cloudy with a medium chance of showers, most likely late morning and afternoon. Winds N–NW 15–20 km/h turning W 15–25 km/h during the afternoon, with stronger westerlies offshore.
Air Temperature: 18°C
Water Temperature: 19°C
Visibility: 6–8 m
Swell: 0.7 m East @ 11.4 s
Tides: High 10:56 am 1.14 m; Low 4:12 pm 0.62 m
Recommended Sites: Bare Island — best protected southern shore option with good ocean flushing; The Steps — good protected Kurnell option if entries remain settled.
Detailed Report
The shore-diving conditions are quite reasonable today. The swell is small, and although the 11.4-second period gives it a little more push than the height suggests, the overall sea state is manageable at protected southern sites. The westerly wind is helpful for many shore entries because it blows away from the coast rather than directly onto the rocks.
Bare Island is the strongest shore recommendation today. The protected side should offer the best balance of entry comfort, marine life and visibility. Aim around the morning high tide for the cleanest water and easiest movement around the shallows.
The Steps and Sutherland Point are also good southern choices. Both should handle today’s small easterly swell reasonably well, though Kurnell entries should still be checked before committing. If the wind makes the surface choppy later in the day, keep the dive plan simple and stay within protected sections.
Oak Park is possible around the afternoon low tide, but it is not as strong a first pick as Bare Island today. Oak Park is sensitive to easterly swell, and 0.7 m is right on its usual comfort threshold. Check the platform before gearing up. If the exit is washing through, move the dive to Bare Island or Kurnell.
Ship Rock is a good protected option if you can dive close to the 10:56 am high slack tide. Outside slack water, current becomes the bigger issue. Lilli Pilli and Camp Cove remain protected fallbacks, but with ocean sites working and visibility better on flushed sites, they are not the first visibility picks today.
Boat diving is the weak point. Offshore winds are strong enough to make exposed boat sites rough, and boat operations may be cancelled rather than moved. If boats run at all, they should stay conservative and avoid exposed offshore reefs.
Water temperature is 19°C. A 5 mm wetsuit is workable for most divers, but longer dives will feel cooler. Bring a torch to make the most of the 6–8 m visibility and to restore colour under ledges and in kelp.
Safety: Shore diving is workable today, but boat diving is likely affected by strong offshore winds. Check entries before gearing up, especially at Oak Park and exposed Kurnell edges.
Dive Tips for Today
- Choose Bare Island for the best all-round shore dive.
- Use The Steps or Sutherland Point for a protected Kurnell-style dive.
- Only dive Oak Park if the platform and exit look settled around low tide.
- Dive Ship Rock only near the 10:56 am high slack tide.
- Treat boat diving as likely affected by strong offshore winds.
Safe dives and happy bubbles!
Weekend Dive Forecast
Saturday: Saturday should be treated as poor for exposed ocean diving. The broader coastal pattern is expected to bring strong southwesterly to southerly winds and a large southerly swell, with powerful surf affecting exposed coastlines. The Steps and Sutherland Point are better protected than Bare Island from southerly energy, but even they should be checked carefully. Ship Rock near high slack, Lilli Pilli, Camp Cove and Shelly Beach are the more conservative protected options. Boat diving is likely to be cancelled or heavily affected.
Sunday: Sunday looks more promising if the swell eases and winds settle. Protected southern sites should improve, especially Bare Island, The Steps and Sutherland Point. Oak Park may be workable around low tide if conditions settle. Boat diving may improve, but it should still be checked on the day because the broader weather pattern remains unsettled.

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.
