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 25 June 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — fair to good diving with sensible site checks. Visibility is sitting around 8 m and there are no runoff issues reported, so today is worth diving if you choose the right southern site. The broad marine forecast shows a 1.5 m S–SSE swell, but the local Botany/Kurnell readings are much shorter-period and smaller inside the bay. That points to manageable diving at protected Kurnell entries rather than a blanket poor-conditions day.
Today’s Dive Plan
The best first pick is The Steps. Aim for the late-morning slack around the 10:29 am low tide, then the first of the incoming tide if the entry is settled. Expect some surface movement and light surge on exposed edges, but the Kurnell headland should give The Steps reasonable shelter from today’s S–SSE energy. If the entry is pushing more than expected, shift nearby to Sutherland Point rather than forcing the dive.
Weekend Conditions Outlook
Best Weekend Window: Sunday currently looks a little cleaner for shore diving if the forecast holds. Saturday still looks diveable at protected southern sites, but showers and a short-period SSE pulse mean site checks remain important.
Saturday: Plan for protected southern sites first. The Steps and Sutherland Point are the best starting calls. Check for E/SE wrap at the entry before committing.
Sunday: Promising, with lighter winds and a manageable SE swell forecast for Cronulla. The Steps, Sutherland Point and Bare Island’s protected side should be kept in play with normal site checks.
Conditions at a Glance
Weather: Partly cloudy with showers likely. Winds S/SE 15–20 km/h around the middle of the day, easing later.
Air Temperature: 18°C
Water Temperature: 18°C
Visibility: Around 8 m
Swell: 1.5 m S–SSE @ around 7–8 s; smaller inside Botany/Kurnell
Tides: Daylight focus — Low 10:29 am 0.67 m; rising late afternoon toward High 5:18 pm 1.66 m
Recommended Sites: The Steps — best protected Kurnell option today; Sutherland Point — conservative nearby alternative if The Steps has too much entry push.
Detailed Report
The offshore and broad coastal forecast looks chunky on paper, but the local bay and entrance readings show shorter-period energy and smaller wave heights inside Botany Bay. That means exposed ledges will still feel active, but protected Kurnell entries should remain workable for divers who take a proper look before gearing up.
The Steps is the right first choice because it handles S and SSE short-period swell better than many open south-facing sites. The late-morning low slack is the most useful daylight tide window. It should give the easiest current management and a sensible entry/exit check before the tide starts pushing back in.
Keep Bare Island and Oak Park as check-only options rather than first recommendations today. Bare Island may have some wrap around the bridge and channel if the S–SSE sets stand up, while Oak Park is more tide and platform dependent. The Leap to Steps is not a general recommendation today; experienced local divers should only consider it after checking The Steps exit first.
Water temperature is a comfortable winter 18°C, but most divers will still be happier in a 5–7 mm suit. Add a hood if you run cold or plan a longer second dive. A torch is worth packing for the ledges and shaded sponge areas, especially if showers darken the water column.
Safety: Check the entry before committing. Watch for surge on the stairs and slippery rock edges, and stay away from exposed platforms if the sets are washing through. If The Steps is moving more than expected, Sutherland Point is the smarter nearby alternative.
Note: Do not downgrade today just because showers are forecast. With no runoff issue reported and around 8 m visibility, the main planning factors are swell wrap, tide timing and entry comfort.
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.
