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 9 July 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — Bare Island protected side first, with a careful entry check. Visibility is around 5 m and the water is 18°C. There is no runoff issue noted, so do not downgrade the day just because showers are forecast. The main factor is the SE swell. The open coast is carrying too much energy for exposed shore entries, but the local Botany readings are smaller inside the bay. That keeps Bare Island in play on the protected side if the bridge, channel and exit are settled.
Today’s Dive Plan
Start with Bare Island’s protected side. The best daylight window is the incoming tide after the 8:46 am low, building toward the 3:26 pm high. This should give the best chance of cleaner water and easier movement around the sheltered side. Check the entry and exit before gearing up. If white water is wrapping into the bridge, channel or exit, move the dive rather than forcing it.
Weekend Conditions Outlook
Best Weekend Window: Saturday morning is the one to watch if the SE swell continues to ease and the wind stays light. The weekend is not a no-check forecast, but it should improve from today if the current trend holds.
Saturday: Keep Bare Island, The Steps and Sutherland Point on the list with normal entry checks. Oak Park remains inspect-only and tide-sensitive if there is still SE pulse on the platform.
Sunday: Reassess locally. Westerly wind may help some ocean-facing sites, but after several days of swell, exposed platforms still need a proper set watch before committing.
Conditions at a Glance
Weather: Partly cloudy with showers likely. Light winds early, tending S to SE through the day. Around 80% chance of showers.
Air Temperature: Around 18°C
Water Temperature: 18°C
Visibility: Around 5 m, best treated as close-range diving conditions
Swell: Effective Botany/Bare Island energy around 1.0–1.3 m SE/ESE @ 10–12 s inside the bay; broader open-coast forecast 2–2.5 m SE
Tides: Botany Bay/Bare Island — High 2:30 am 1.41 m; Low 8:46 am 0.56 m; High 3:26 pm 1.65 m; Low 9:54 pm 0.68 m
Recommended Sites: Bare Island protected side — best first look with the incoming tide; Camp Cove — sheltered fallback if Bare Island is wrapping or too surgy.
Detailed Report
Today is a site-check day, not an open-coast day. The SE swell is still carrying enough size and period to move a lot of water around exposed platforms and corners. That rules out exposed shore entries as a general recommendation. Inside Botany Bay, however, the measured wave energy is smaller, so Bare Island’s protected side remains the best first call from the local note.
Bare Island should be approached as a protected-side dive today. Stay away from exposed corners if sets are wrapping, and make the bridge, channel and exit check the deciding factor. The incoming tide into the 3:26 pm high should give the best chance of cleaner water and easier navigation.
Visibility is around 5 m, so keep the dive slow and close. This is a good day for nudibranchs, octopus, cuttlefish and smaller reef life rather than wide scenic swimming. Use good buddy positioning and make sure everyone is comfortable with the lower visibility before heading away from the entry.
Oak Park, Voodoo, The Leap and Leap to Steps are not recommended today. The open-coast swell has too much SE energy for those entries and exits. The Steps and Sutherland Point may be worth a look for experienced local divers if Kurnell is clearly settled, but the SE angle can wrap into entries there, so Bare Island protected side remains the better first recommendation.
There is no runoff issue noted today. Showers alone are not the main visibility concern. The bigger factors are surge, swell wrap and suspended sand near entries. If the water looks brown, milky or full of debris at the site, keep the dive shallow and conservative or move to a more protected option.
Water temperature is 18°C. Most divers will be comfortable in a 5–7 mm wetsuit, with a hood recommended for longer dives or anyone who feels the cold. Pack a torch for ledges, shaded sponge areas and lower-light sections in the 5 m visibility.
Safety: Check the entry and exit before committing. Do not dive Bare Island if white water is wrapping into the bridge, channel or exit. Avoid exposed platforms today, stay close to your buddy, and move to Camp Cove or call the dive if the protected 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.
