Sydney Diving Conditions – Friday 14 August 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — good shore diving with Oak Park the best first look, but use the low-tide window. 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 main planning points are the southerly swell, the tide and the Oak Park platform check. Oak Park is today’s local first call, especially around the low-to-mid tide window if the entry and exit are clean.
Today’s Dive Plan
Start with Oak Park and aim for the afternoon low-tide window around 3:13 pm, or the early incoming tide after it if there is enough useful light. Oak Park is normally friendliest at low to mid tide. The 9:24 am high may still be worth a check if the sea is calm, but do not treat high tide as automatic because the platform can become less forgiving if sets are washing through.
Weekend Conditions Outlook
Best Weekend Window: Saturday morning is worth planning if the swell and wind stay moderate, but it still needs a local platform check. Sunday looks more unsettled, with rain and a stronger easterly/southeasterly influence more likely.
Saturday: Keep Oak Park, The Steps, Sutherland Point and Bare Island protected side in play with normal checks. Oak Park remains best away from high tide.
Sunday: Reassess locally before committing. If the easterly or southeasterly swell stands up, favour The Steps, Sutherland Point and Bare Island protected side before exposed platforms.
Conditions at a Glance
Weather: Sunny to mostly sunny. S winds around 15–20 kt on coastal waters; lighter inside enclosed water, with seas below 0.5 m there.
Air Temperature: Around 18–20°C near the coast
Water Temperature: 17°C
Visibility: 6–10 m, best away from shallow surge zones
Swell: S swell 1–1.5 m inshore, 1.5–2 m offshore; short-to-moderate period movement, with Oak Park best judged by the platform and exit.
Tides: Port Hacking/Oak Park — Low 3:24 am 0.06 m; High 9:24 am 1.43 m; Low 3:13 pm 0.21 m; High 9:34 pm 1.79 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 good shore-diving day with sensible site checks. The local note puts Oak Park on top, visibility is a useful 6–10 m, and there is no runoff issue to worry about. The southerly swell has enough size to make exposed entries worth checking properly, but it is not a reason to move straight to fallback-only thinking.
Oak Park is the right first recommendation because it is ocean-flushed and should make the most of the better visibility. The platform is the key. Watch several full sets before gearing up. If the entry stays clear between sets and the exit looks simple, it should be a rewarding dive.
The tide is important today. Oak Park is usually best at low to mid tide, which makes the 3:13 pm low the best planning marker. The morning high at 9:24 am gives plenty of water, but higher water can make the platform less friendly if the southerly sets are washing through. Treat the morning high as a check, not an automatic green light.
With 6–10 m visibility, Oak Park should be good for blue gropers, Port Jackson sharks, octopus, nudibranchs, sponge life and close reef detail. If the first few metres near the entry are stirred, slow down, 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. Because today’s southerly swell is 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 the general recommendations today. Experienced local divers may check Leap to Steps only after checking The Steps exit first, but Oak Park, The Steps, Sutherland Point and Bare Island protected side are the more practical calls for most divers.
There is no runoff issue noted, and rain is not a factor today. The main comfort and safety checks are swell direction, platform movement, tide stage and whether the exit stays 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.
