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 – Sunday 5 July 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — The Steps first, with active reassessment through the day. Visibility is around 7 m and the water is 18°C. The key local note is that The Steps has just been physically checked and looks great. That makes it today’s first shore call, but this is not a set-and-forget day. A strong southerly pattern is building, so divers should keep the plan conservative and be ready to move to Sutherland Point or Monument if the entry starts to push.
Today’s Dive Plan
Start at The Steps while the site remains settled from the morning check. The most useful tide reference is the 11:57 am high tide, with slack water around that window helpful for Kurnell navigation. Watch the stairs and exit for several full sets before gearing up. If the swell builds, if surge starts wrapping into the entry, or if the exit looks harder than the entry, shift the dive to Sutherland Point or Monument rather than forcing The Steps.
Conditions at a Glance
Weather: Cloudy with showers increasing. S/SW winds around 20–30 km/h over land, with stronger southerly winds on the water under a Strong Wind Warning.
Air Temperature: Around 16°C
Water Temperature: 18°C
Visibility: Around 7 m
Swell: Building S to SSE swell; protected Kurnell entry currently checked as workable, but broader open-coast swell is 2.5–4 m with 11–13 s energy through the day
Tides: Kurnell/Botany Bay — Low 5:51 am 0.51 m; High 11:57 am 1.39 m; Low 5:28 pm 0.72 m; High 11:45 pm 1.68 m
Recommended Sites: The Steps — first choice after a positive physical check; Sutherland Point or Monument — move here if The Steps starts to surge or the swell builds.
Detailed Report
Today is a local-check day. On paper, the marine forecast is rough, with strong southerly wind and powerful southerly swell building along the open coast. That rules out exposed shore sites and makes boat diving a very cautious proposition. For shore diving, the important difference is that The Steps has been checked in person and is currently looking good.
The Steps is the right first recommendation because it is a protected Kurnell option in southerly conditions and it has the strongest local observation behind it this morning. Expect some movement on exposed edges, but if the entry and exit remain clean, the site should give the best balance of shelter, visibility and marine life today.
The tide plan is simple: use slack water around the 11:57 am high if the site remains settled. Kurnell dives are generally easier around slack because current movement is reduced and navigation is more comfortable. Do not treat the high tide as automatic permission to dive, though. The swell is building, so the entry and exit check is more important than the clock.
If conditions change during the day, move early. Sutherland Point is the conservative nearby option if The Steps starts getting pushy. Monument is also worth considering if it is sitting cleaner and more protected on the day. Avoid exposed sites such as Oak Park, Voodoo, The Leap and Leap to Steps today. The open-coast swell has too much size and period for committed exits.
Visibility is around 7 m, which is workable for Kurnell reef diving. Showers alone are not the main visibility concern today. The bigger issue is surge: if the swell starts lifting sand and weed around the shallows, expect the visibility to drop quickly near the entry and on exposed corners.
Water temperature is 18°C. Most divers will be comfortable in a 5–7 mm wetsuit, but a hood is a good idea for longer dives or anyone who feels the cold. Pack a torch for ledges and sponge areas, as cloud and showers will reduce light underwater.
Safety: This is a conservative shore-diving day. Check The Steps again before entering, watch several full sets, and make the exit the deciding factor. Do not dive if surge is running across the stairs or if the exit looks difficult. If the swell builds during the day, move to Sutherland Point or Monument, or call the dive.
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.
