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 – 23 June 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — protected southern sites only. Sydney’s diving season is giving us useful water quality today, with 8–10 m visibility possible where the site is sheltered from the southerly swell. The weather is friendly, with mostly sunny skies and light winds around shore, but the ocean is still active. The short-period southerly swell will put surge and white water into exposed entries, so keep the dive plan protected and avoid forcing open rock-platform sites.
Today’s Dive Plan
The best first call is The Steps at Kurnell, with Sutherland Point as the more conservative backup if sets are pushing. Aim for the incoming tide after the 9:05 am low, with the most useful window from late morning into the early afternoon. The 3:40 pm high tide is helpful for slack-water planning, but it is late in the daylight window, so keep the dive simple and allow plenty of time for exit and pack-up. This suits certified divers who are comfortable with normal shore entries, conservative navigation and a bit of surge management. Check the entry for three full sets before committing.
Weekend Planning Conditions
Best Weekend Conditions: Too early to call strongly, but Saturday currently looks slightly better than Sunday. Both days have a shower risk in the forecast, so water quality and runoff will be the main watch points if rain arrives later in the week.
Conditions at a Glance
Weather: Mostly sunny, 10% rain chance, light winds around shore; exposed coastal waters S–SW 18–28 km/h, up to 37 km/h offshore during the morning and early afternoon.
Air Temperature: 17°C
Water Temperature: 18°C
Visibility: 8–10 m in protected water; moderate confidence, no runoff issues.
Swell: 1.5–1.7 m S @ 7 s, increasing to 1.5–2.0 m offshore.
Tides: Daylight tides — Low 9:05 am 0.61 m; High 3:40 pm 1.55 m
Recommended Sites: The Steps — best protected southern option on the incoming tide; Sutherland Point — safer backup if surge wraps into the entry.
Detailed Report
The encouraging part of today is the water quality. With no runoff issues and 8–10 m visibility reported, divers should find pleasant clarity at protected southern sites. The limiting factor is the southerly swell. It is not a long-period groundswell, but at 1.5 m plus it will still put regular movement into shallow gutters, exposed corners and rock-platform exits.
The Steps is the best match today because it has better shelter from southerly energy than the more exposed Kurnell entries. Keep the route conservative. Stay away from surge channels, avoid pushing wide if the water is moving, and turn the dive early enough to exit with daylight and energy to spare. Sutherland Point is the sensible second option if The Steps is moving more than expected.
This is not an Oak Park, Voodoo or Leap-to-Steps day. Oak Park will be too exposed to the southerly pulse, and The Leap needs much flatter entry conditions than today is offering. Bare Island is also not the first recommendation with this much southerly swell. If you inspect it and the protected side is clearly calm, experienced locals may find a careful option, but do not push the outside or any exit with white water crossing it.
Timing matters. The morning low is at 9:05 am, then the tide rises toward the 3:40 pm high. For Kurnell, use the incoming tide and stay as close to slack water as practical. The afternoon high can help settle movement, but it is late in the day, so plan a clean, short dive rather than a long exploration. If you choose Shiprock as a fallback, dive it only close to high slack and carry an SMB because boat traffic is part of the site plan.
Water temperature is 18°C. A 5–7 mm suit is right for most divers, with a hood or vest for anyone doing a longer second dive. Take a torch for ledges and sponge life, and carry an SMB if there is any chance of surfacing away from your planned exit.
Safety: Watch three full sets before entering. If the entry is surging, the exit is washing over, or visibility is being stirred up close to the rocks, change site early. Today rewards good judgement and protected-site discipline.
Note: There is a worthwhile dive available today, but it is not a day for exposed shore entries. Choose The Steps or Sutherland Point first, keep Lilli Pilli ready as the sheltered fallback, and let the entry conditions make the final decision.
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.
