Diving Conditions in Sydney
Welcome to Sydney's most reliable and up-to-date dive conditions page. Every morning, our team checks the tides, visibility, water temperature, swell, and weather to recommend the best Sydney dive sites for the day.
Whether you're planning a weekend dive, checking if today’s conditions are safe, or just dreaming about your next underwater adventure, this is your go-to source. Bookmark this page and check back daily for the latest updates.
I treated the attached prompt as a request to generate today’s report. I checked the supplied inputs against the BOM coastal and enclosed-waters forecasts: BOM has no NSW marine warnings, coastal winds variable about 10 kt becoming NE 10–15 kt this evening, seas below 1 m, and an inshore southerly swell of 1–1.5 m, while enclosed waters are lighter with seas below 0.5 m. Your supplied local data still points to very good shore-diving conditions: 0.6 m S swell at 8.6 seconds, 19°C water, 8–10 m visibility, and Oak Park as the lead site.
Sydney Diving Conditions – Saturday 11 July 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — fair shore diving with Oak Park the best first look. Visibility is around 5 m and the water is 18°C. There is no runoff issue noted, so the main planning factors are swell period, tide and platform safety. The broad coastal forecast still shows SE swell, but the nearshore Cronulla signal is easing through the day. That keeps Oak Park in play, especially around the late-morning low tide, provided the platform is not washing.
Today’s Dive Plan
Start with Oak Park. The best practical window is late morning around the 10:59 am low tide, then the early part of the incoming tide if the platform stays settled. Watch a few full sets before gearing up. If water is running across the platform, if the exit looks slippery and pushy, or if divers are being knocked around in the shallows, move the dive rather than forcing it.
Sunday Outlook
Sunday is also worth planning, but it comes with stronger wind offshore. The surf trend looks smaller for Cronulla, which may help shore diving, but the coastal forecast has stronger NW to W wind and a Strong Wind Warning for Sydney Coast. Keep shore sites on the list with normal checks, but be conservative with boats, exposed platforms and late-day wind exposure. Oak Park, The Steps and Bare Island’s protected side are the first checks if the local water looks settled.
Conditions at a Glance
Weather: Cloud clearing with a mostly sunny afternoon. Early fog possible. Light winds early, becoming N/NE around 10–15 kt during the afternoon.
Air Temperature: Around 18–19°C
Water Temperature: 18°C
Visibility: Around 5 m, best treated as close-range reef and macro conditions
Swell: Effective Cronulla nearshore swell around 1.1 m SE @ 9 s easing toward 0.9 m ESE @ 10–11 s; broader Sydney Coast forecast SE swell around 1.5 m
Tides: Port Hacking/Oak Park — High 5:11 am 1.18 m; Low 10:59 am 0.43 m; High 5:36 pm 1.73 m
Recommended Sites: Oak Park — best first look around low tide if the platform is clean; The Steps or Bare Island protected side — sensible alternatives if Oak Park is washing.
Detailed Report
Today is not a flat-sea day, but it is a workable shore-diving day with the right timing. The SE swell is still present, and the 9–11 second period will put some push into the shallows. The important point is that the trend is easing and the wind is light early, so Oak Park deserves a proper look rather than being written off from the broad coastal swell number alone.
Oak Park is the first recommendation because it is ocean-flushed and matches today’s local note. The late-morning low tide is the key. Oak Park is normally friendliest at low to mid tide, when the platform is easier to read and the exit is less likely to be washed by small sets. Avoid pushing the site around the late afternoon high if waves are running across the platform.
Visibility is around 5 m, so keep the dive slow and close. This is a good day for blue gropers, sponge life, nudibranchs, Port Jackson sharks and smaller reef detail rather than wide scenic swimming. Stay close to your buddy and keep navigation simple, especially if the swell stirs sand or weed near the entry.
If Oak Park is not behaving, move early. The Steps is the better Kurnell alternative if the entry is settled, while Bare Island’s protected side is worth checking if divers want a more sheltered shore plan. Sutherland Point is another conservative Kurnell option if The Steps has too much E/ESE wrap.
Voodoo, The Leap and Leap to Steps are not general recommendations today. Experienced local divers may consider more exposed options only after checking the exit first, but for most groups Oak Park, The Steps or Bare Island protected side are the better calls.
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 sections, especially with visibility sitting around 5 m.
Safety: Make the Oak Park platform check the deciding factor. Watch several full sets before entering. Do not enter if water is washing across the platform, if surge is pushing divers around in the shallows, or if the exit looks harder than the entry. Move to The Steps, Bare Island protected side or Sutherland Point if the ocean side is more active than expected.
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.
