Sydney Diving Conditions – 19 May 2026
Updated Daily by Local Experts
Today remains a protected-site style diving day around Sydney, with moderate ENE swell continuing to push surge into many exposed shore entries. The good news is that winds remain relatively light for most of the day, helping surface conditions stay manageable despite the 1.6 m swell. Visibility is sitting around 4–6 m, with recent rain and swell energy still stirring up sediment around shallower reefs. Bare Island remains the best ocean option today, although divers should expect moderate surge and use the protected eastern side.
Conditions at a Glance
Weather: Cloudy with a very high chance of rain easing later tonight. Light winds becoming southwesterly 15–20 km/h this afternoon.
Air Temperature: 21°C
Water Temperature: 20°C
Visibility: 4–6 m
Swell: 1.6 m ENE @ 9.4 s
Tides: High 10:19 am 1.28 m; Low 3:45 pm 0.45 m
Recommended Sites: Bare Island — protected eastern side remains workable for experienced divers; Lilli Pilli — highly protected fallback with calmer entries.
Detailed Report
Today’s ENE swell continues to make exposed Sydney shore dives uncomfortable, particularly around shallow ledges and open entries. While the swell period is only moderate at 9.4 seconds, the 1.6 m height is enough to produce steady surge and reduce visibility around many of the open coast reefs.
Bare Island remains the best ocean choice today, but conditions are definitely more suited to experienced local divers comfortable managing surge and changing entry conditions. The eastern side provides the best shelter from the ENE swell, and diving closer to the morning high tide will improve comfort and reduce turbulence around the shallows.
Oak Park is not recommended today. The easterly swell is well above the site’s comfortable operating range, and entries and exits are likely to be rough and surgey, particularly around low tide.
The Steps and Sutherland Point remain more protected than many Sydney ocean sites and are sensible fallback options if Bare Island feels too uncomfortable. Shelly Beach and Lilli Pilli become increasingly attractive options for divers wanting calmer entries and easier conditions.
Camp Cove is also worth considering today for divers wanting protected harbour conditions away from the ocean swell.
Boat diving conditions remain marginal offshore. Winds are not especially strong, but the ENE swell is creating uncomfortable movement on exposed reefs and reducing overall diving quality offshore. Easier protected boat dives such as Henry Head are the better option for confident divers if boats are running.
Water temperature remains steady at 20°C. A 5 mm wetsuit remains ideal, and a torch will help considerably in today’s reduced visibility.
Safety: Today’s swell is producing strong surge around exposed shore entries and shallow reef sections. Conditions may appear manageable from shore but feel significantly more active underwater. Assess entry and exit conditions carefully before committing.
Dive Tips for Today
- Plan dives closer to the morning high tide for calmer entries.
- Use protected eastern-side entries at Bare Island.
- Consider Ship Rock, Lilli Pilli or Camp Cove if ocean entries feel uncomfortable.
- Expect stronger-than-normal surge around shallow reefs and bommies.
Safe dives and happy bubbles!
Weekend Dive Forecast
Saturday: Current forecast suggests around 1.5 m easterly swell at 10.8 seconds. Conditions are likely to remain marginal at exposed shore sites, with moderate surge continuing around Bare Island, Oak Park and exposed Kurnell entries. Protected southern sites and harbour options will remain the better choices. Offshore boat diving may become uncomfortable on exposed reefs.
Sunday: Forecast currently suggests around 1.6 m easterly swell with ongoing swell energy. Protected shore dives should remain workable, but exposed entries are likely to stay surgey and less suitable for newer divers.

The Steps – Swell-sensitive
Protected, but exposed to E to ESE swells greater than 1m.
Sutherland Point – Best on an incoming tide
Well protected. Only exposed to ESE swell greater than 1.8m.
Bare Island – Best with N swell and incoming tide
Should not be dived if S swell is greater than 1.2m.

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.
