Sydney Diving Conditions – Sunday 2 August 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — Oak Park first, but only after a serious platform check. Visibility is sitting around 5–10 m and the water is 18°C. There is no runoff issue supplied in today’s local note, so water quality is not the main concern. The key issue is the SE swell. Oak Park is today’s local first call, but the swell has enough size and period to make entry and exit safety the deciding factor.
Today’s Dive Plan
Start with Oak Park around the late morning high-tide window, then reassess as the tide drops. The 10:54 am high gives the best early water level, while the afternoon low at 4:42 pm may expose the platform but comes with a stronger SE swell signal and less useful daylight. Watch several full sets before gearing up. If water is washing across the platform or the exit looks pushy, move the dive to The Steps, Sutherland Point, or Bare Island.
Early Week Outlook
Monday: Conditions look more favourable if the swell eases as forecast. Oak Park, The Steps and Bare Island are all worth checking, with Oak Park still tide and platform dependent.
Tuesday: A smaller southerly swell should keep southern sites in play, but a fresh local check is still needed before using exposed entries.
Conditions at a Glance
Weather: Mostly sunny. Light variable winds early, becoming N/NE 15–20 kt in the early afternoon.
Air Temperature: Around 16–17°C near the coast
Water Temperature: 18°C
Visibility: 5–10 m, best away from shallow surge zones
Swell: SE 2 m easing toward 1.5 m around midday; Cronulla nearshore around 1.4 m SSE @ 11 s in the morning, building to 1.6 m SE @ 12 s late afternoon
Tides: Port Hacking/Oak Park — Low 4:56 am 0.27 m; High 10:54 am 1.32 m; Low 4:42 pm 0.44 m; High 10:53 pm 1.57 m
Recommended Sites: Oak Park — best first look if the platform is clean; The Steps, Sutherland Point, or Bare Island — safer alternatives if Oak Park is washing.
Detailed Report
Today is a useful but cautious Oak Park call. The local note puts Oak Park on top, and visibility is a solid 5–10 m, but the SE swell has enough size and period to make the platform check essential. This is not a day to gear up before looking carefully at the entry and exit.
Oak Park should be assessed from the platform before anyone commits. Watch several full sets. If the platform stays clear between sets and the exit looks simple, the dive is worth considering. If water is running across the platform, or if surge is already moving divers around in the shallows, shift the plan immediately.
The morning high at 10:54 am gives the best early tide reference. Oak Park often likes low to mid tide, but today’s swell period means very low water later in the afternoon could make the platform and exit less forgiving. Treat the afternoon low as a fresh site check, not an automatic second window.
Visibility should sit somewhere between 5 and 10 m, with the better water likely away from the shallow wash zone. Keep the dive slow and close if it is nearer the lower end of the range. Oak Park can still be rewarding today for blue gropers, Port Jackson sharks, octopus, nudibranchs, sponge life and close reef detail.
If Oak Park is not clearly manageable, The Steps is the best next southern check. Sutherland Point is the more conservative nearby option if The Steps has too much entry movement. Bare Island is also a practical alternative today because the issue is SE swell at Oak Park rather than runoff or poor water quality.
Voodoo, The Leap and Leap to Steps are not general recommendations today. The SE swell and 11–12 second period make exposed exits less forgiving. Experienced local divers should only consider more exposed sites after checking the exit first and confirming conditions are genuinely settled.
There is no runoff issue supplied today, so ordinary weather is not the reason to downgrade the dive. The main comfort and safety checks are swell period, platform movement, shallow surge, tide stage and whether the exit remains clean for the whole group.
Water temperature is 18°C. Most divers will be comfortable in a 5–7 mm wetsuit, with a hood recommended for longer dives or anyone who feels the cold. Pack a torch for ledges, shaded reef sections and better colour if visibility sits closer to 5 m.
Safety: Make the Oak Park exit check the deciding factor. Do not enter 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, Sutherland Point, Bare Island or call the dive if Oak Park is not clearly safe.
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.
