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 – Thursday 2 July 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — fair to good protected shore diving, with Bare Island’s eastern side the best first look. Visibility is sitting around 5–10 m and the water remains 18°C. The offshore forecast is windy, with a Strong Wind Warning for Sydney Coast, but the enclosed-water and Botany Bay readings are much smaller. That keeps Bare Island’s eastern side in play, especially on the morning incoming tide.
Today’s Dive Plan
Start with Bare Island’s eastern side. The best window is the incoming tide into the 9:52 am high. This should give the best chance of cleaner water, easier navigation and a more settled entry. If diving later, reassess after the 3:15 pm low as the tide starts to rise again, but expect more wind influence and more variable surface conditions.
Weekend Conditions Outlook
Best Weekend Window: Saturday morning may offer the better early window if the southerly swell is still building, but the weekend forecast needs close checking. BOM is flagging a shift toward stronger southerly conditions and larger, more powerful waves over the weekend.
Saturday: Start with protected southern sites only after a site check. The Steps, Sutherland Point and Bare Island’s protected side are the sensible first checks. Avoid exposed platforms if the southerly swell arrives early.
Sunday: Treat as a protected-site or reassessment day if the forecast holds. Large southerly energy is likely to make exposed shore entries uncomfortable and may reduce visibility around open corners.
Conditions at a Glance
Weather: Slight early shower chance, then sunny. N/NW winds around 15–25 km/h around Sydney, stronger offshore under a Strong Wind Warning.
Air Temperature: Around 23°C
Water Temperature: 18°C
Visibility: 5–10 m, best chance on Bare Island’s eastern side with the incoming tide
Swell: Effective Botany/Bare Island wave energy around 0.2–0.35 m inside the bay, with small 11–12 s pulse; broader coastal forecast E–NE swell around 1 m
Tides: Botany Bay/Bare Island — Low 4:00 am 0.49 m; High 9:52 am 1.33 m; Low 3:15 pm 0.66 m; High 9:49 pm 1.84 m
Recommended Sites: Bare Island – eastern side — best incoming-tide visibility and protection today; The Steps or Sutherland Point — conservative southern alternatives if Bare Island is too wind-affected.
Detailed Report
Today is a good shore-diving example of separating offshore hazard from protected-site reality. The open coast has a Strong Wind Warning and rougher seas, so boats and exposed platforms deserve caution. Inside Botany Bay, the measured wave energy is much smaller, which keeps Bare Island’s eastern side workable for divers who make a proper entry and exit check.
Bare Island’s eastern side is the best first recommendation. The incoming tide into the 9:52 am high should bring the cleanest water of the day and help the 5–10 m visibility sit toward the better end of the range. Keep the route simple and avoid pushing around exposed corners if wind chop or white water starts to wrap.
The afternoon is a fresh site-check window rather than an automatic second dive. After the 3:15 pm low, the tide starts rising again, but the wind may be more noticeable and the surface can become choppier around the bridge and open water. If the entry looks messy, move the dive instead of forcing it.
The Steps and Sutherland Point are sensible alternatives if Bare Island is wind-affected or if the visibility looks patchy. Both still need a normal entry and exit check. Voodoo, The Leap and other exposed open-coast shore entries are not the right call today with the offshore wind warning and E–NE energy in the water.
Water temperature is 18°C. Most divers will be comfortable in a 5–7 mm wetsuit, with a hood for longer dives or anyone who feels the cold. Pack a torch for shaded ledges, sponge gardens and swim-throughs, especially if visibility sits closer to 5 m than 10 m.
Safety: Keep today as a protected shore-diving plan. Check the bridge, entry and exit before committing. Avoid exposed platforms, and stay close to your buddy if wind chop or variable visibility reduces comfort underwater.
Safe dives and happy bubbles!

Good except for a NE swell greater than 1.4m.
Oak Park – Best on low tide

VooDoo – Best on high tide
Best with SW to NW swells. All other swells must be under 0.5m.
Cape Solander – Tide has no effect
Best with SW to NW swells. Other swells must be below 0.7m.
The Leap – Best near high tide
Should not be dived if E to S swell is greater than 1m. Best on an incoming tide.
The Steps – Swell-sensitive
Protected, but exposed to E to ESE swells greater than 1m.
Sutherland Point – Best on an incoming tide
Well protected. Only exposed to ESE swell greater than 1.8m.
Bare Island – Best with N swell and incoming tide
Should not be dived if S swell is greater than 1.2m.

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.
