Sydney Diving Conditions – 29 May 2026
Updated Daily by Local Experts
Today is not a great day for diving in Sydney. A 1.9 m southerly swell, fresh S–SW winds, and several days of rain are making exposed ocean sites surgy, messy, and low-visibility. Protected shore sites are the only sensible options, but even the sheltered harbour and river sites may have poor visibility from runoff. Shelly Beach is the best practical option today, with Camp Cove as a calm-water fallback if you accept very limited visibility.
Conditions at a Glance
Weather: Partly cloudy with a medium chance of showers, easing this afternoon. Winds S–SW 20–30 km/h.
Air Temperature: 20°C
Water Temperature: 19°C
Visibility: 3–5 m on better ocean edges; likely lower in harbour and river runoff areas
Swell: 1.9 m South @ 7.4 s
Tides: Low 12:27 pm 0.50 m; High 7:08 pm 1.64 m
Recommended Sites: Shelly Beach — best protected shore option from today’s southerly swell; Camp Cove — calm-water fallback, but expect reduced visibility after rain.
Detailed Report
The open coast is carrying too much southerly energy today for comfortable shore diving at exposed sites. The swell period is not long, so the surge is shorter, pushier, and more constant rather than deep and powerful, but the 1.9 m height is still enough to make rock entries and exits uncomfortable.
Visibility is the other issue. The supplied 3–5 m estimate is reasonable for the better flushed ocean edges, but runoff is now starting to affect the protected sites. Camp Cove, Lilli Pilli and other enclosed-water options may be calm, but they can easily turn green and silty after rain. Today, calm water does not necessarily mean good diving.
Shelly Beach is the best overall recommendation because it gives good shelter from the southerly swell while still having more ocean influence than many harbour or river sites. It may not be crystal clear, but it is likely to offer the best balance of protected entries and reasonable diving.
Camp Cove is a calm fallback, not a visibility pick. Use it if entry comfort is the priority, but expect reduced visibility from recent rain and harbour runoff. Lilli Pilli is also highly protected, but after rain inside Port Hacking, it should be treated as a last-resort sheltered option rather than a preferred dive.
Bare Island, Oak Park, The Steps, The Leap and Voodoo should all be downgraded today. Bare Island and The Steps may have protected pockets, but the swell, wind and low visibility make them poor first choices for most divers.
Ship Rock could be considered close to the 7:08 pm high slack tide, but that is a late window and visibility may still be affected by runoff and low light. It is not the most practical daytime recommendation today.
Boat diving is likely to be poor. Southerly swell, fresh S–SW winds and unsettled water make exposed offshore reefs uncomfortable, 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 worthwhile for comfort. Take a torch, keep navigation simple, and avoid dives that depend on good visibility.
Safety: Choose protected entries today. Avoid exposed rock platforms and do not assume harbour or river sites will have good visibility just because they are calm.
Dive Tips for Today
- Choose Shelly Beach as the best balance of protection and water movement.
- Use Camp Cove only if calm entry is more important than visibility.
- Treat Lilli Pilli as a protected last-resort fallback because runoff may reduce visibility.
- Avoid Bare Island, Oak Park, The Leap, The Steps and Voodoo as first-choice sites.
- Expect low visibility and keep the dive plan simple.
Safe dives and happy bubbles!
Weekend Dive Forecast
Saturday: Saturday looks better than today but is still marginal at exposed sites, with around 1.3 m easterly swell at 9.6 seconds. The Easterly swell will wrap into Oak Park, The Steps, and exposed Kurnell entries, so protected sites remain the smarter choice. Bare Island may improve if entries settle, but Shelly Beach, Ship Rock near slack and Sutherland Point are likely to be more comfortable. Visibility may remain mixed after recent rain, especially in enclosed-water sites.
Sunday: Sunday looks more workable, with around 1.0 m SE swell at 9.1 seconds. Protected southern sites should improve, particularly Bare Island’s protected side, The Steps and Sutherland Point. Oak Park remains a cautious call because SE swell above 0.7 m can still affect entries and exits. Boats may improve, but offshore conditions should still be checked on the day.

VooDoo – Best on high tide
Best with SW to NW swells. All other swells must be under 0.5m.
Cape Solander – Tide has no effect
Best with SW to NW swells. Other swells must be below 0.7m.
The Leap – Best near high tide
Should not be dived if E to S swell is greater than 1m. Best on an incoming tide.
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

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.
