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 – 18 June 2026

Updated Daily by Local Experts

Today is a good Sydney diving day, with mostly sunny weather, 8–10 m visibility and a small ENE swell. Bare Island is the best all-round shore pick, especially around the late morning high tide. Oak Park may also be worth considering around the afternoon low tide if the platform is settled.

Conditions at a Glance

• Weather: Mostly sunny. Light winds becoming northerly 15–20 km/h in the middle of the day. Coastal winds N–NW about 10 kt, increasing to 15–20 kt during the morning.
• Air Temperature: 22°C
• Water Temperature: 19°C
• Visibility: 8–10 m
• Swell: 0.6 m ENE @ 9.8 s
• Tides: High 11:03 am 1.28 m; Low 4:30 pm 0.46 m
• Recommended Sites: Bare Island — best all-round site with good protection and visibility; Oak Park — possible around low tide if the platform is settled.

Detailed Report

The morning looks clean and inviting, with light northwesterly influence before the northerly flow freshens later. The ENE swell is small and manageable, but it may still wrap into some southern entries and create a little movement on exposed corners.

Visibility should sit around 8–10 m at the better ocean-flushed sites. There are no runoff concerns today, and the swell is not large enough to stir protected reefs heavily. Expect the best water quality around the incoming and high tide window.

Bare Island is the strongest shore recommendation today. It should offer the best balance of entry comfort, visibility, marine life and shelter from the ENE swell. Aim for the protected side and the late morning high tide for the easiest conditions.

Oak Park is a useful secondary option around the 4:30 pm low tide, but check the platform before gearing up. The ENE swell is small enough to make it possible, but if the sets are washing through the exit, move to Bare Island or Kurnell. The Steps and Sutherland Point should also be good protected southern options.

Boat Diving Outlook

Boat diving looks suitable today at appropriate Sydney sites, especially through the morning and early main dive window. The swell is small, seas are low early, and winds are below the Abyss 25 kt maximum. The main operational watch point is the northerly wind freshening to 15–20 kt and seas building to around 1–1.5 m during the afternoon.

Henry Head is the easiest protected boat option. Magic Point should also be realistic if local chop stays manageable and pickup conditions match the forecast. More exposed offshore reefs should be assessed separately by the skipper, especially later in the day if northerly chop increases.

Water temperature is 19°C. A 5 mm wetsuit is suitable for most divers, with a hood or vest useful for longer dives. Bring a torch to bring back colour under ledges and in sponge gardens, even with good visibility.

Caution: Conditions are favourable, but ENE swell and later northerly wind can make exposed entries and boat pickups less comfortable than the morning suggests. Check the site before committing, especially at Oak Park, Voodoo and exposed offshore reefs.

Dive Tips for Today

• Choose Bare Island as the best all-round shore dive.
• Dive Oak Park around the 4:30 pm low tide only if the platform is settled.
• Use The Steps or Sutherland Point for protected Kurnell-style diving.
• Time Ship Rock around the 11:03 am high slack tide.
• Boat diving looks suitable, with Henry Head and Magic Point both realistic depending on skipper judgement and afternoon chop.

Safe dives and happy bubbles!

Weekend Dive Forecast

Saturday: Saturday looks good for shore diving, with 0.6 m SE swell at 12.1 seconds. The swell height is small, but the longer period means exposed entries may get occasional stronger sets. Bare Island, The Steps and Sutherland Point should be the strongest shore options. Oak Park may be possible around low tide if the platform is settled, while Voodoo and The Leap should be downgraded unless the sea is genuinely calm. Boat diving is likely site-dependent early, with westerly winds around 15–20 kt and seas easing later. Henry Head is the better first boat choice, while Magic Point needs skipper confirmation.

Sunday: Sunday looks favourable, with 0.5 m easterly swell at 10.6 seconds. The small height should keep protected southern sites workable, though easterly swell can wrap into Oak Park and Kurnell corners. Bare Island, The Steps, Sutherland Point and Oak Park should all be considered if the actual sets stay small. Boat diving should look normal at appropriate inshore sites if winds remain light, with Henry Head and Magic Point the practical first recommendations.

How Conditions Affect Dive Sites

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.
