Sydney Diving Conditions – Wednesday 5 August 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — good shore diving with Oak Park the best first look. Visibility is sitting around 8–10 m and the water is 18°C. There is no runoff issue noted, and the broader southerly swell is below 1 m, so southern ocean sites are well in play. Oak Park is today’s best first call, especially around the morning low to early incoming tide if the platform is clean.
Today’s Dive Plan
Start with Oak Park. The best practical window is the morning low tide at 6:45 am and the early incoming tide after it. Oak Park is normally friendliest at low to mid tide, so the morning window is the best fit. The 1:09 pm high may still be diveable if the sea is very calm, but do not treat high tide as automatic. Check the platform, watch several full sets, and make the exit the deciding factor.
Rest of Week Outlook
Thursday: Still worth planning. The forecast has a modest southerly swell around 1–1.5 m and easing winds, so Oak Park, The Steps and Bare Island are all worth checking. Oak Park remains best away from high tide.
Friday: Looks promising if the forecast holds. Light winds and a smaller southerly swell should keep southern shore sites in play, with Oak Park, The Steps and Bare Island all reasonable first checks.
Conditions at a Glance
Weather: Sunny. Westerly winds around 15–20 km/h over land, with W 15–20 kt on coastal waters and lighter conditions inside enclosed water.
Air Temperature: Around 19°C
Water Temperature: 18°C
Visibility: 8–10 m
Swell: Southerly below 1 m on the broader Sydney coast; low-energy conditions at Cronulla, with normal Oak Park platform checks still required
Tides: Port Hacking/Oak Park — High 12:20 am 1.35 m; Low 6:45 am 0.37 m; High 1:09 pm 1.43 m; Low 7:29 pm 0.52 m
Recommended Sites: Oak Park — best first look with good visibility and small swell; The Steps or Bare Island — good alternatives if Oak Park’s platform is unexpectedly washing.
Detailed Report
Today is a good winter shore-diving day. The local note puts Oak Park on top, visibility is a useful 8–10 m, and there is no runoff issue to worry about. The broader southerly swell is below 1 m, and the westerly wind should keep the ocean side tidy. This is a day for normal site checks, not fallback-site thinking.
Oak Park is the right first recommendation because the swell is small, the visibility is good, and the site should benefit from clean ocean flushing. The morning low and early incoming tide give the best platform shape. If the entry stays dry between sets and the exit looks simple, it should be a rewarding dive.
The tide is the main planning point. Oak Park is usually best at low to mid tide. The 1:09 pm high has plenty of water, but higher water can make the platform less forgiving if even small sets are washing through. Check again before committing around high tide rather than assuming the morning conditions still apply.
With 8–10 m visibility, Oak Park should be good for blue gropers, Port Jackson sharks, octopus, nudibranchs, sponge life and close reef detail. Once you are away from the shallow entry zone, the visibility should make navigation easier than it has been on recent lower-viz days.
The Steps is a good alternative if Oak Park is not behaving, while Bare Island is also in play today. Under the Bare Island naming rule, today’s south swell is below 1.1 m, so there is no need to limit the wording to “Bare Island protected side.” The whole site can be considered with normal local checks.
Experienced local divers may consider Leap to Steps after checking The Steps exit first. It is not the general recommendation, but today’s small southerly swell and offshore wind make it worth a look for confident divers if the exit is clearly calm.
There is no runoff issue noted, and rain is not a factor today. The main comfort and safety checks are platform movement, tide stage, shallow surge and whether the exit stays clean for the whole group.
Water temperature is 18°C. Most divers will be comfortable in a 5–7 mm wetsuit. Add a hood if you feel the cold or plan a longer second dive. Pack a torch for ledges and shaded reef sections; it will bring out colour even with good visibility.
Safety: Make the Oak Park exit check the deciding factor. Watch several full sets before entering. Do not dive if water is washing across the platform, if surge is pushing through the shallows, or if the exit looks harder than the entry. Move to The Steps, Bare Island or call the dive if Oak Park is not clearly manageable.
Safe dives and happy bubbles!

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.
