Sydney Diving Conditions – Tuesday 11 August 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — Oak Park first, but make it an early-to-midday site check. Visibility is around 8 m and the water is a cool 16°C. There is no runoff issue noted, so water quality is not the main concern. The key planning point is timing: the morning southerly swell is still manageable, but the broader coastal forecast has the south swell building strongly during the afternoon. Oak Park is today’s best first look, especially around the low-to-mid tide window if the platform is clean.
Today’s Dive Plan
Start with Oak Park and aim for the late-morning to midday window around the 12:51 pm low tide. Oak Park is normally friendliest at low to mid tide, and the westerly wind should help the surface early. Watch several full sets before gearing up. If the south swell arrives early, if water is washing across the platform, or if the exit looks harder than the entry, move the dive to The Steps, Sutherland Point, or Bare Island protected side.
Midweek Outlook
Wednesday: Treat as a protected-southern-site check. The southerly swell is forecast to remain elevated early before easing, so start with The Steps, Sutherland Point and Bare Island protected side before considering Oak Park.
Thursday: Conditions may improve if the swell drops locally, but another southerly pulse is possible. Use the morning site check before committing to exposed platforms.
Friday: Looks more settled at this stage, with lighter enclosed-water conditions. Oak Park, The Steps and Bare Island may all be worth checking if the swell trend continues to ease.
Conditions at a Glance
Weather: Sunny. W winds 25–35 km/h over land, easing late; W 15–20 kt on coastal waters, reaching 25 kt offshore during the morning.
Air Temperature: Around 21°C
Water Temperature: 16°C
Visibility: Around 8 m
Swell: Southerly around 1 m early, building to 2–3 m during the afternoon on the broader coast; secondary NE swell around 1 m. Oak Park is an early-window, platform-check call.
Tides: Port Hacking/Oak Park — Low 1:27 am 0.16 m; High 7:14 am 1.21 m; Low 12:51 pm 0.33 m; High 7:21 pm 1.86 m
Recommended Sites: Oak Park — best first look around low tide if the platform is clean; The Steps, Sutherland Point, or Bare Island protected side — safer options if the afternoon southerly swell arrives early.
Detailed Report
Today is a good early-window shore-diving opportunity, but it is not a whole-day green light for exposed platforms. The local note puts Oak Park on top, visibility is a useful 8 m, and there is no runoff issue to worry about. The concern is the southerly swell trend. It starts around a manageable level, then builds sharply on the broader coast during the afternoon.
Oak Park is the right first recommendation because the tide timing is favourable and the westerly wind should keep the ocean side cleaner through the earlier part of the day. The best plan is to check the platform around late morning and the 12:51 pm low tide. If the entry stays clear between sets and the exit looks simple, Oak Park should be a rewarding dive.
The tide is helpful today. Oak Park is usually best at low to mid tide, and the 12:51 pm low gives the platform its best shape. The evening high at 7:21 pm is not a general recommendation because it falls after practical daylight and the swell is forecast to be larger by then.
With 8 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, navigation should be comfortable, provided the swell has not started stirring the shallows.
If Oak Park is not clearly manageable, move early. The Steps is the best Kurnell alternative if the entry is settled, while Sutherland Point is the more conservative nearby option. Because the southerly swell is forecast to build above 1.1 m, Bare Island should be treated as a protected-side option today rather than a whole-island assumption.
Voodoo, The Leap and Leap to Steps are not the general recommendations today. The morning may tempt experienced local divers, but the building southerly swell makes exposed exits a poor bet unless they have been physically checked and are clearly calm. For most groups, Oak Park early, then The Steps, Sutherland Point or Bare Island protected side is the better plan.
There is no runoff issue noted, and rain is not a factor today. The main comfort and safety checks are platform movement, tide stage, the southerly swell trend and whether the exit stays clean for the whole group.
Water temperature has dropped to 16°C, so dress warmer than the past week. A 7 mm wetsuit is the better call for most divers, and a hood is strongly recommended for longer dives or anyone who feels the cold. Pack a torch for ledges and shaded reef sections; it will bring out colour and help with close-up life even in decent 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. Keep today early and conservative, and move to The Steps, Sutherland Point, Bare Island protected side or call the dive if the south swell stands up earlier than forecast.
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.
