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 – 11 June 2026
Updated Daily by Local Experts
Today is another excellent Sydney diving day, with small swell, light winds and visibility around 8–10 m at the better ocean-flushed sites. Most shore sites should be workable, including exposed sites that need calm seas. Voodoo is the standout advanced shore option, while Bare Island, Oak Park and The Steps are all strong choices for certified divers.

Detailed Report
The sea is small, the wind is light, and conditions are lining up very well for Sydney diving today. The only weather caution is the chance of showers and a possible thunderstorm, so keep an eye on the sky and avoid being exposed on rock platforms or boats if cells build during the day.
The 0.6 m ENE swell is short-period at 6.6 seconds, so it should not produce much powerful surge at depth. Exposed entries still need a proper check, but the overall swell pattern is very friendly. Visibility should sit around 8–10 m at the better ocean sites, especially where water is flushed by the incoming tide.
Voodoo is today’s standout for experienced divers. It is very exposed and only suits genuinely calm seas, but today’s small swell gives it a realistic window. Watch a few sets before gearing up and only commit if the entry and exit are settled.
Bare Island is the best all-round option for most divers. It offers easier entry choices than Voodoo, strong marine life and good visibility through the sponge gardens and kelp. Oak Park should also be excellent around the 10:18 am low tide if the platform is calm. The Steps and Sutherland Point should be comfortable throughout the day, with the incoming tide improving conditions toward the afternoon high.
Dive Tips for Today
- Choose Voodoo only if the entry and exit are genuinely calm.
- Use Bare Island as the best all-round shore option.
- Dive Oak Park around the 10:18 am low tide if the platform is settled.
- Time Ship Rock around the 4:53 pm high slack tide.
- Boat diving looks suitable, with Magic Point and Henry Head both realistic options depending on skipper judgement.
Safe dives and happy bubbles!
Weekend Dive Forecast
Saturday: Saturday looks close to ideal for Sydney diving, with 0.3 m SSE swell at 12.9 seconds. The swell height is very small, so most shore sites should be in play, including Bare Island, Oak Park, The Steps, Sutherland Point and possibly Voodoo if the actual sets stay small. The longer period means exposed entries should still be checked carefully, but overall conditions look excellent. Boat diving should look normal at suitable sites, including Magic Point and Henry Head, provided winds remain within operating limits.
Sunday: Sunday also looks very good, with 0.6 m ENE swell at 12.3 seconds. The longer period gives the swell more push than the height suggests, so exposed corners still need checking, but the overall forecast remains favourable. Bare Island, Oak Park, The Steps and Sutherland Point should all be good options. Voodoo may be possible if the sea remains genuinely settled. Boat diving should remain suitable at appropriate sites, with Magic Point and Henry Head the best practical recommendations.

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.
