Sydney Diving Conditions – Thursday 13 August 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — Oak Park first, but make it a tide and platform check. Visibility is sitting around 6–10 m and the water is 17°C. There is no runoff issue noted, so water quality is not the main concern. The key planning point is the southerly swell building through the morning. Oak Park is today’s local first call, but the entry and exit must be clean before committing.
Today’s Dive Plan
Start with Oak Park, with the best practical window around the low-to-mid tide period leading into the 2:37 pm low. Oak Park is normally friendliest at low to mid tide, while high tide can make the platform and exit less forgiving if sets are washing through. Watch several full sets before gearing up. If water is running across the platform, if surge is moving divers around in the shallows, or if the exit looks harder than the entry, move the dive to The Steps, Sutherland Point, or Bare Island protected side.
Weekend Conditions Outlook
Best Weekend Window: Friday looks the better near-term shore-diving window if the swell drops as forecast. Saturday and Sunday need closer local checks, with southerly wind and swell becoming more relevant again.
Friday: More promising. Light W/SW to SE winds and smaller southerly swell should keep Oak Park, The Steps and Bare Island in play with normal site checks. Oak Park remains best away from high tide.
Saturday: Reassess locally. If the southerly swell lifts, favour The Steps, Sutherland Point and Bare Island protected side before committing to exposed platforms.
Sunday: Still a check-first day. Keep site choices practical and avoid broad optimism until the morning surf and wind are confirmed.
Conditions at a Glance
Weather: Mostly sunny. W/SW winds 15–20 kt on coastal waters, turning southerly 10–15 kt during the afternoon; lighter and calmer inside enclosed water.
Air Temperature: Around 15–16°C near the coast
Water Temperature: 17°C
Visibility: 6–10 m, best away from shallow surge zones
Swell: Southerly below 1 m early, increasing to 1–2 m during the morning on the broader coast; nearshore south pulse around 8–9 s. Oak Park is platform-check only.
Tides: Port Hacking/Oak Park — Low 3:02 am 0.08 m; High 8:51 am 1.34 m; Low 2:37 pm 0.25 m; High 8:59 pm 1.87 m
Recommended Sites: Oak Park — best first look around low to mid tide if the platform is clean; The Steps, Sutherland Point, or Bare Island protected side — safer options if Oak Park is washing.
Detailed Report
Today is a useful Oak Park call, but not a no-check day. The local note puts Oak Park on top, visibility is a good 6–10 m, and there is no runoff issue to worry about. The caution is the southerly swell trend. It starts smaller, then builds through the morning, so entry and exit safety matter more than the headline visibility.
Oak Park is the right first recommendation because the tide gives a strong low-water window and the local note supports the site. The 2:37 pm low is the best planning marker. Low to mid tide usually gives the platform a better shape and makes the exit easier to judge. Do not treat the 8:51 am high as automatic; if sets are washing through at high water, wait for the tide to drop or move the dive.
The swell period is not extreme, but the rising trend means divers should be patient at the platform. Watch several full sets, not just one quiet gap. If the platform stays clear between sets and the exit looks simple, Oak Park should be rewarding. If the south swell has arrived early and water is washing across the exit, shift sites immediately.
With 6–10 m visibility, Oak Park should offer good close reef detail. Expect blue gropers, Port Jackson sharks, octopus, nudibranchs, sponge life and the usual reef fish activity. If the first few metres near the entry are stirred up, move slowly, keep the route simple and stay close to your buddy until the water opens up.
If Oak Park is not clearly manageable, The Steps is the best Kurnell alternative if the stairs and exit are settled. Sutherland Point is the more conservative nearby option if The Steps has too much wrap or current. Because today’s southerly swell is forecast to build above 1.1 m, Bare Island should be treated as Bare Island protected side rather than a whole-island recommendation.
Voodoo, The Leap and Leap to Steps are not general recommendations today. Experienced local divers may consider more exposed options only after physically checking the exit, but the building south swell makes them a poor first call for most groups.
There is no runoff issue noted, and ordinary weather is not the visibility problem today. The main comfort and safety checks are swell trend, platform movement, tide stage and whether the exit remains clean for the whole group.
Water temperature is 17°C. Most divers will be happier in a 7 mm wetsuit, or a warm 5 mm with hood and good layers. A hood is strongly recommended for longer dives. 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. Move to The Steps, Sutherland Point, Bare Island protected side 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.
