Dive Conditions – 19 April 2025
Sydney’s current diving conditions are improving as the day progresses. While the morning might present some challenges with fog in the western suburbs and reduced underwater visibility, conditions are expected to get better throughout the day. With a mostly sunny afternoon and calmer swell as the day goes on, divers can look forward to a more enjoyable experience. Bare Island stands out as today’s recommended site, but it’s wise to thoroughly check conditions at any site before committing.
Conditions at a Glance:
Weather: The chance of morning fog, mainly in the western suburbs. Mostly sunny afternoon. Light winds. Large and powerful surf conditions are expected to be hazardous for coastal activities such as rock fishing, swimming, and surfing.
Air Temperature: Max 29°C
Water Temperature: 22°C
Visibility: 4-5m
Swell: 1.3m height (falling), ESE direction, 12-second period
High Tide: at 12:31 pm (1.21m)
Recommended Sites: Bare Island, but check conditions closely before committing. Everywhere is expected to improve as the day progresses.
Sydney is starting the day with some coastal fog lingering in the western suburbs, but the forecast for a mostly sunny afternoon should brighten things up nicely. Light winds and a high of 29°C make for pleasant topside conditions as the day wears on. That said, powerful surf remains a factor, so exercise extreme caution with any shore entries or other coastal activities.
Underwater, the water temperature remains at a steady 22°C, providing consistently comfortable conditions for divers. Visibility is a bit on the lower side at just 4-5 metres, due to the remaining sediment churned up by recent strong surf. However, the good news is that as the swell continues to fall and the water settles through the day, visibility is likely to improve.
The swell sits at 1.3 metres and is steadily dropping, with an ESE direction and a period of 12 seconds. This is much less challenging than previous days, but care is still needed, especially at open or exposed sites. Timing your dives around the high tide at 12:31 pm will help ensure smoother entries and exits and less surge during your underwater exploration.
Enjoy your dives today, and don’t forget to take in the beauty of Sydney’s incredible marine world. Stay mindful of the conditions, and have a fantastic day out in the water!

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 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.
