Sydney Diving Conditions – 4 March 2026
Updated Daily by Local Experts
Conditions remain workable today with a modest ENE swell and improving visibility compared with earlier in the week. Weather will be unsettled with showers and the possibility of thunderstorms later in the day, so the best dive window is clearly the morning. Bare Island is the top choice, offering protection from the ENE swell and more stable entries than most exposed sites.
Conditions at a Glance
Weather: Partly cloudy. High chance of showers easing early afternoon. Possible thunderstorms later today. Winds light becoming NE 15–25 km/h early afternoon.
Air Temperature: 27°C
Water Temperature: 19°C
Visibility: 4–6 m
Swell: 0.8 m ENE @ 7.9 s
Tides: High 9:50 am 1.82 m; Low 4:12 pm 0.33 m
Recommended Site: Bare Island — sheltered from ENE swell with reliable entry conditions and typically better clarity.
Detailed Report
A modest 0.8 m ENE swell with a short 7.9-second period means light but consistent surge around exposed edges. Because the swell is coming from the ENE, many open southern platforms will feel more wrap and surface movement once the northeasterly winds build through the afternoon.
Why Bare Island: Bare Island’s protected channel breaks up the incoming swell and usually provides calmer entries than surrounding ocean sites in ENE conditions. With visibility around 4–6 metres, it should offer the most consistent diving today. Timing your dive close to the 9:50 am high tide will generally bring the cleanest water and easier navigation around the bommies.
Water temperature has dipped slightly to around 19°C. Expect the usual Bare Island marine life — blue gropers, schools of old wives and the chance of spotting weedy seadragons along the kelp-covered reef.
Safety: Plan dives early before winds strengthen and storms develop later in the day. Check surge at the entry point, maintain close buddy contact in reduced visibility, and exit the water early if weather deteriorates.
Weekend Dive Forecast
Looking ahead to the weekend, the overall pattern remains influenced by a slow-moving high pressure system over the Tasman Sea maintaining an onshore easterly airflow along the NSW coast. This means typical late-summer conditions: moderate easterly swell, onshore breezes building during the day, and the best dive windows in the mornings.
Saturday: Forecast swell around 0.7 m ENE should keep most southern sites diveable with mild surge. Early morning will again be the best window before the seabreeze builds. Bare Island and Oak Park are likely to be the top shore options, with the ocean sites offering the best visibility due to stronger water exchange.
Sunday: Swell is expected to increase slightly to around 1.1 m ENE. This will bring a more noticeable surge on exposed entries and could reduce options slightly. Bare Island’s protected channel should still work, while other open platforms may become marginal depending on sets. Plan dives early and assess entry conditions carefully.
Overall, the weekend still offers reasonable diving opportunities for experienced shore divers, provided dives are planned early in the day and sites with protection from the easterly swell are chosen.
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.
