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 – Monday 13 July 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — very good ocean-shore diving, especially for experienced local divers. Visibility is around 8 m and the water is 18°C. There is no runoff issue noted. The local call is very positive, with Voodoo the best first look and ocean sites generally in play. The nearshore swell is tiny, and the westerly wind should keep the open coast clean and settled.
Today’s Dive Plan
Start early at Voodoo if your group is experienced and comfortable with exposed shore entries. The best practical window is around the 7:08 am high tide and the early falling tide after it. By the 12:38 pm low, the platform and exit become less forgiving, so treat late morning as a fresh site check rather than an automatic continuation of the morning conditions.
Conditions at a Glance
Weather: Mostly dry and mild. WNW winds around 20 km/h early, easing WSW/NW around 10 km/h through the day.
Air Temperature: Around 19°C
Water Temperature: 18°C
Visibility: Around 8 m
Swell: Effective Voodoo nearshore swell around 0.2–0.3 m S/SSW @ 7–11 s, with a minor 0.2 m ESE/S secondary pulse
Tides: Kurnell/Voodoo — Low 1:16 am 0.34 m; High 7:08 am 1.38 m; Low 12:38 pm 0.51 m; High 7:19 pm 2.08 m
Recommended Sites: Voodoo — best advanced ocean-shore option in today’s very flat seas; Oak Park — easier ocean-side alternative if the platform is clean; The Steps — conservative Kurnell option for groups wanting a simpler entry.
Detailed Report
Today is one of those winter windows divers wait for. The sea is very flat, the wind is favourable, and visibility is sitting around 8 m. That opens up the ocean sites, with Voodoo the standout first recommendation for confident local divers.
Voodoo suits today’s setup because the swell is tiny and the westerly influence should keep the surface cleaner than recent easterly or southerly patterns. Expect better water away from the shallow wash zone, with good boulder terrain, sponge life, schooling fish and the chance of larger reef life moving along the edge.
The tide still matters. The 7:08 am high gives Voodoo its best shape, with the early falling tide also useful while the exit remains settled. The 12:38 pm low is less friendly for the platform, so reassess carefully if you are diving late morning. The 7:19 pm high is strong on paper, but it is not a general recommendation because it falls after practical daylight.
Voodoo is not a beginner site, even on a very flat day. Check the exit first, watch several full sets, and make sure every diver in the group is comfortable with the entry and return route. If there is any unexpected push across the platform, move the plan instead of forcing the dive.
Oak Park is a sensible second choice for divers wanting an easier ocean-side shore dive. It should also benefit from the flat-sea pattern, but still check the platform and avoid entering if water is washing across the exit. Experienced divers may also consider The Leap to The Steps, but only after checking The Steps exit first.
For newer divers or groups wanting a more conservative plan, The Steps and Bare Island’s protected side are both worth keeping in play. Conditions are good enough that true fallback sites are not needed today unless a local entry check looks unexpectedly poor.
There is no runoff issue noted, so today should not be downgraded for water quality. The main visibility factors are local surge, tide stage and how much shallow water is stirred near the entry. With 8 m visibility, this is a good day for reef detail, sponge gardens, Port Jackson sharks, blue gropers, nudibranchs and close marine-life encounters.
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 boulder sections, and carry an SMB if there is any chance of surfacing away from the planned exit.
Safety: Voodoo is for experienced local divers only. Flat seas make it attractive, but they do not remove the need for a proper exit check. Watch several sets, keep the dive plan conservative, and move to Oak Park, The Steps or Bare Island protected side if Voodoo is not clearly calm.
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.
