Sydney Diving Conditions – 28 May 2026
Updated Daily by Local Experts
Today is a marginal but workable day for experienced divers at protected Sydney sites. The main issue is easterly swell with an 11-second period, plus showers and a possible afternoon thunderstorm, reducing visibility and comfort. Bare Island is the best southern ocean option, but use the protected side only and expect surge around exposed corners. If conditions look messy on arrival, Lilli Pilli, Ship Rock near high slack, or Camp Cove are the more sensible protected fallbacks although their visibility will be down due to recent rain.
Conditions at a Glance
Weather: Cloudy with a very high chance of showers and the chance of a thunderstorm late afternoon and evening. Light winds becoming southerly 15–25 km/h; coastal winds S–SE 10–15 knots, reaching up to 20 knots inshore during the day.
Air Temperature: 21°C
Water Temperature: 19°C
Visibility: 3–5 m
Swell: Around 1.2 m East @ 11 s, with larger easterly energy offshore and exposed sets possible
Tides: Low 11:52 am 0.48 m; High 6:31 pm 1.59 m
Recommended Sites: Bare Island
Detailed Report
The easterly swell is the main operational factor today. At around 11 seconds, it has enough period to push surge into shallow ledges and exposed corners, even though the reported height is only moderate at protected locations. The open coast will feel more active than the numbers suggest, especially once the southerly wind builds during the day.
Visibility is likely to sit around 3–5 m. Runoff is not expected to be a major issue early, but showers and possible thunderstorms may reduce clarity later, particularly in harbour, bay and river-influenced areas. Keep navigation simple and do not rely on long-distance visibility between landmarks.
Bare Island is the best ocean-site option today, but only if the protected entry is behaving. Watch the water for a few sets before committing. Avoid exposed corners and shallow bommies where the easterly swell wraps through. If the entry is washing through, move the dive rather than forcing it.
Ship Rock is still a good protected option, but timing matters. Today’s best Ship Rock window is close to the 6:31 pm high slack tide, when the current should ease and navigation will be easier. Lilli Pilli and Camp Cove are the more conservative choices if the ocean surge is stronger than expected, although the recent rain and runoff over the past couple of days will likely reduce visibility at both sites — especially at Lilli Pilli — with greener water and lower clarity despite their protection from the swell.
Boat diving is marginal today. Wind may reach around 20 knots inshore, with showers and possible thunderstorms adding operational uncertainty. If boats run, protected or easier options such as Henry Head are the sensible choices. Exposed offshore reefs should be downgraded.
Water temperature is 19°C. A 5 mm wetsuit is workable, but a hood or vest is worthwhile for longer dives. Bring a torch for the lower visibility and keep the dive plan simple.
Safety: Today suits divers who are comfortable assessing entries and relocating if needed. Do not commit to exposed rock platforms if surge is washing through the entry or exit.
Dive Tips for Today
- Use Bare Island’s protected side only if the entry is calm enough.
- Avoid Oak Park, The Leap, Leap to Steps and Voodoo.
- Treat The Steps as a possible relocation risk under today’s easterly swell.
- Use Ship Rock only near high slack tide around 6:31 pm.
- Carry a torch and expect 3–5 m visibility on ocean sites.
Safe dives and happy bubbles!
Weekend Dive Forecast
Saturday: Saturday remains marginal, with around 1.3 m easterly swell at 9.6 seconds and fresh southwesterly to westerly wind expected on the coastal waters. The wind direction may help some shore entries, but the swell will still affect exposed ocean sites. Bare Island’s protected side, Ship Rock, Sutherland Point and Lilli Pilli are the better shore choices. Oak Park, The Leap, Leap to Steps and Voodoo should be downgraded. Boat diving is likely affected by wind and sea state.
Sunday: Sunday looks more workable, with swell easing toward 1.0 m SE at 9.1 seconds. Protected southern sites should improve, especially The Steps, Sutherland Point and Bare Island if entries settle. Oak Park remains a cautious call because the SE swell remains above its usual comfort threshold. Boat diving may improve, but should still be assessed on the day if the wind remains fresh offshore.

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.
