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 – Friday 17 July 2026

Updated Daily by Local Experts

Today’s Dive Conditions

Plan — fair to good protected southern diving, with The Steps the best first look. Visibility is around 5 m and the water is 18°C. There is no runoff issue noted, so do not downgrade the day just because showers are forecast. The main planning factors are the southerly swell, the tide window and the entry/exit check. The Steps is the best match today because it gives good southern protection while still offering proper Kurnell reef diving.

Today’s Dive Plan

Start with The Steps and aim for the morning high-slack window around 10:39 am. Kurnell dives are generally easier around slack water, and this is the best daylight tide reference today. If diving later, reassess carefully as the tide falls toward the 4:18 pm low, because the entry and exit can feel more exposed if sets are pushing through.

Weekend Conditions Outlook

Best Weekend Window: Saturday looks worth planning, with moderate SE wind, seas around 1 m and a mixed southerly/easterly swell. Sunday needs a closer check because the easterly swell is forecast to build.

Saturday: Keep The Steps, Sutherland Point and Bare Island’s protected side as the first checks. Oak Park remains inspect-only and tide-sensitive if the platform is washing.

Sunday: Reassess locally before committing. If the easterly swell builds as forecast, favour protected southern sites and avoid exposed platforms unless the morning check is clearly settled.

Conditions at a Glance

• Weather: Cloudy to partly cloudy with showers likely, most likely near the coast. S/SE winds around 10–15 kt, easing later in sheltered water.
• Air Temperature: Around 18–19°C
• Water Temperature: 18°C
• Visibility: Around 5 m, best treated as close-range reef and macro conditions
• Swell: Southerly 1–1.5 m on the broader coast, with shorter-period nearshore energy easing through the day; expect some movement on exposed edges
• Tides: Botany Bay/Kurnell — Low 4:38 am 0.26 m; High 10:39 am 1.48 m; Low 4:18 pm 0.50 m; High 10:42 pm 1.95 m
• Recommended Sites: The Steps — best protected Kurnell option around slack; Sutherland Point — conservative nearby alternative if The Steps has too much entry push.

Detailed Report

Today is a sensible Kurnell shore-diving day, not an exposed-ocean day. The southerly swell is still enough to move water around open platforms, but it is not strong enough to rule out protected southern sites. Using effective swell rather than just the broad coastal number, The Steps is the right first recommendation.

The Steps should give the best balance of shelter, reef life and workable visibility. Expect around 5 m visibility, so keep the dive slow, stay close to your buddy and focus on sponge gardens, ledges, nudibranchs, octopus, blue gropers and weedy seadragon territory rather than long scenic swims.

The tide matters today. The morning high at 10:39 am is the best reference point because Kurnell dives are easier around slack. If the entry is settled, the window around high water should give the most comfortable dive. Later in the day, the falling tide toward the 4:18 pm low needs a fresh check, especially if surge starts working across the shallows.

Sutherland Point is the right nearby move if The Steps is pushing more than expected. It gives a simpler, more conservative Kurnell option while keeping divers away from the most exposed ocean platforms. Bare Island protected side may also be worth a look if the water is clean and the bridge area is not wrapping, but The Steps remains the first call from today’s local note.

Oak Park, Voodoo, The Leap and Leap to Steps are not the general recommendations today. Experienced local divers may check more exposed sites only if the entries and exits are clearly calm, but for most groups The Steps or Sutherland Point is the better plan.

There is no runoff issue noted, so ordinary showers are not the main visibility problem. The bigger visibility factors are surge, tide stage and suspended sand or weed near the entry. If the water looks milky or stirred up at the stairs, keep the dive conservative or shift to Sutherland Point.

Water temperature is 18°C. Most divers will be comfortable in a 5–7 mm wetsuit, with a hood recommended for longer dives or anyone who feels the cold. Pack a torch for ledges, shaded sponge areas and lower-light sections in the 5 m visibility.

Safety: Check the stairs and exit before committing. Watch several full sets, and do not enter if surge is running across the entry or if the exit looks harder than the entry. Stay close to your buddy in the lower visibility, and move to Sutherland Point if The Steps is more active than expected.

Safe dives and happy bubbles!

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.
