Weekend Diving Preview
Detailed Report
Today’s conditions have worsened slightly compared to yesterday. The swell has increased to 0.8m with a shorter period of 5.5 seconds, creating more challenging entry and exit conditions in exposed areas. Visibility has dropped to a range of 5-10 metres, and seas are expected to rise further throughout the day. Divers are advised to assess conditions on-site before venturing into the water.
The weather forecast includes a high chance of showers, especially in the late morning and early afternoon. A maximum air temperature of 21°C coupled with shifting winds from northerly to northwesterly adds to the overall variability of conditions. Planning your dives around low tide at 12:39 pm can help avoid the rougher seas in exposed regions.
Bare Island is the standout site for today, offering protected and flat seas, making it the safest option for a quality shore-dive experience. Exposed sites, on the other hand, may be significantly rougher, so physical checks are essential to ensure safety. Take extra care today and focus on enjoying Sydney’s vibrant underwater scenes at the most suitable locations.

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.
