Sydney Diving Conditions – 9 May 2026
Updated Daily by Local Experts
Today offers fair but slightly surgy diving conditions around Sydney, with a moderate 1.4 m southerly swell and fresh westerly winds helping to flatten surface conditions at many shore entries. Visibility is sitting around 4–5 m, so expect greener water and some suspended sediment, particularly around exposed headlands. The Steps at Kurnell is the standout option today thanks to its protection from southerly swell and more manageable entry conditions.
Conditions at a Glance
Weather: Sunny. Westerly winds 20–30 km/h, turning southwesterly 15–20 km/h during the afternoon and evening.
Air Temperature: 20°C
Water Temperature: 20°C
Visibility: 4–5 m
Swell: 1.4 m South @ 10.9 s
Tides: Low 8:00 am 0.68 m; High 2:00 pm 1.24 m
Recommended Sites: The Steps — best protected from today’s southerly swell; Sutherland Point — reliable protected fallback option in southerly conditions.
Detailed Report
The combination of moderate southerly swell and strong offshore westerly winds is creating mixed but workable conditions for protected Sydney shore dives today. Westerly winds are helping keep surface chop down at many southern entries, but the 10.9-second swell period still carries enough energy to create noticeable surge around exposed reef edges and rock platforms.
The Steps is the best overall pick today. The Kurnell headland provides useful protection from the south swell, and entries should remain manageable for experienced Open Water divers. Visibility is not spectacular, but conditions should improve slightly around the incoming tide and toward the afternoon high.
Bare Island is becoming marginal today. While the westerly wind helps flatten the surface, the 1.4 m southerly swell is right on the upper operational limit for the site and surge around the corners will likely make entries and exits uncomfortable for many divers. If conditions worsen during the day, shore dives may be relocated to more protected sites.
Ship Rock remains a reliable protected option, especially closer to the afternoon high tide, while Lilli Pilli offers a highly protected fallback if conditions become too surgey elsewhere, although visibility there is usually lower than the open coast.
Boat diving today is likely to be rougher offshore despite the offshore winds, with residual southerly swell still producing movement on open-coast sites. More exposed offshore reefs, such as Magic Point and Bypass Reef, are best left to confident divers only.
Water temperature remains comfortable at 20°C. A 5 mm wetsuit should suit most divers today, though visibility levels mean a torch will still improve colours and marine-life spotting under ledges and in kelp sections.
Safety: Expect surge at exposed entries and around shallow reef edges. Check conditions carefully before committing to shore entries, especially at Bare Island and exposed Kurnell sites.
Safe dives and happy bubbles!
Weekend Forecast
Saturday: Conditions remain moderately surgey with a 1.4 m southerly swell at 10.9 seconds. Offshore westerly winds help shore entries at protected southern sites, but exposed locations will still feel the swell energy. The Steps, Sutherland Point and Ship Rock are the best choices today.
Sunday: Conditions improve noticeably as swell drops to around 0.9 m south at 9 seconds. Surge eases considerably and visibility should improve slightly. Bare Island, Oak Park, and The Steps should all become more comfortable options, while offshore boat diving becomes more practical again if winds remain light.
Summary
Today is best suited to protected southern shore dives rather than exposed offshore sites. The Steps, Sutherland Point and Ship Rock are the standout options for Saturday. Bare Island is borderline and may require relocation depending on surge during the day.
Sunday becomes much more flexible, with calmer seas reopening Bare Island and easier offshore diving opportunities. Conditions should suit a broader range of divers by Sunday morning.

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.
