Sydney Diving Conditions – Sunday 26 July 2026
Updated Daily by Local Experts
Today’s Dive Conditions
Plan — Oak Park first, but only after a clean platform check. Visibility is around 5 m and the water is 18°C. There is no runoff issue noted, so the main planning factors are the southerly swell, the low-tide window and entry/exit safety. Oak Park is today’s local first call, but the southerly pulse still has enough size and period to make the platform inspect-only.
Today’s Dive Plan
Start with Oak Park around the late-morning low tide at 11:51 am, then the early incoming tide if the platform remains settled. Watch several full sets before gearing up. If water is washing across the platform, if the exit looks slippery and pushy, or if surge is moving divers around in the shallows, move the dive to The Steps or Sutherland Point rather than forcing Oak Park.
Early Week Outlook
Monday: Conditions should ease, with lighter wind and a smaller southerly swell trend. The Steps, Bare Island protected side and Oak Park are worth checking, with Oak Park still best around low to mid tide.
Tuesday: Looks promising if the easing trend continues. Westerly winds and smaller swell should open more southern shore options, but exposed sites still need a proper entry and exit check after the recent southerly energy.
Conditions at a Glance
Weather: Mostly sunny to partly cloudy. W/SW winds 15–20 kt early, easing and turning S/SE below 10 kt during the afternoon.
Air Temperature: Around 19°C
Water Temperature: 18°C
Visibility: Around 5 m, best treated as close-range reef and macro conditions
Swell: Southerly swell around 2 m on the broader coast; Cronulla nearshore pulse around 1.7 m S @ 11 s early, easing trend expected through the day
Tides: Port Hacking/Oak Park — Low 12:51 am 0.47 m; High 6:22 am 1.04 m; Low 11:51 am 0.56 m; High 6:29 pm 1.54 m
Recommended Sites: Oak Park — best first look around low tide if the platform is clean; The Steps or Sutherland Point — safer southern alternatives if Oak Park is washing.
Detailed Report
Today is a site-check day with a useful low-tide Oak Park window. The local note puts Oak Park on top, and the late-morning low tide suits the platform. The caution is the southerly swell period. Even if the wind is favourable and the sea is easing, an 11-second southerly pulse can still push water across the platform and make the exit less forgiving.
Oak Park should be checked before anyone gears up. Stand and watch several full sets, not just one quiet gap. If the platform stays clear between sets, the exit looks simple and the shallows are not surging hard, the dive is worth considering. If the water is running across the platform or the exit looks harder than the entry, move the plan immediately.
The best timing is the low-tide window around 11:51 am and the early incoming tide after it. Oak Park is normally friendliest at low to mid tide. The evening high is not a general recommendation because it sits close to fading light and the platform can become less forgiving if any swell is still pushing through.
Visibility is around 5 m, so keep the dive slow and close. This is a good day for blue gropers, Port Jackson sharks, octopus, nudibranchs, sponge life and close reef detail rather than long scenic swims. Keep navigation simple and stay close to your buddy from the start.
If Oak Park is not clearly manageable, The Steps is the best next check. It offers better protection from southerly energy and keeps divers on a proper southern reef site. Sutherland Point is the more conservative nearby option if The Steps has too much entry push.
Voodoo, The Leap and Leap to Steps are not recommended for general divers today. The weather may look good, but the southerly pulse and exposed exits make those sites a poor first call unless experienced local divers have physically checked the exit and found it clearly calm.
There is no runoff issue noted, and rain is not a factor today. The main visibility and comfort checks are swell period, platform movement, shallow surge and tide stage.
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 reef sections and better colour in the 5 m visibility.
Safety: Make the Oak Park exit check the deciding factor. Do not enter if water is washing across the platform, if surge is pushing through the shallows, or if the exit looks harder than the entry. Move to The Steps, Sutherland Point or call the dive if Oak Park is not clearly safe.
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.
