Sydney Diving Conditions – 20 February 2026
Updated Daily by Local Experts
Good summer diving conditions this morning with solid visibility and manageable swell. The main consideration will be increasing northeasterly winds through the late morning and possible showers later in the day. The Steps at Kurnell is the best overall option.
Conditions at a Glance
Weather: Cloudy. Medium chance of showers. Possible thunderstorm later. Winds easing early, becoming NE 15–25 km/h during the morning.
Air Temperature: 26°C
Water Temperature: 23°C
Visibility: 8–12 m
Swell: 0.6 m SSE @ 8.4 s
Tides: High 11:03 am 1.77 m; Low 5:23 pm 0.32 m
Recommended Site: The Steps (Kurnell) – sheltered from SSE swell and reliable in northeasterly winds.
Detailed Report
A modest 0.6 m SSE swell with an 8 second period is producing light to moderate surge on exposed southern faces, but protected sites are holding well. Visibility is very respectable at 8–12 metres, which is excellent for this time of year.
The Steps is the best call today. It offers solid protection from the SSE swell and handles a northeasterly breeze better than more exposed sites. Plan your dive around the 11:03 am high tide for the cleanest water and easiest navigation. As winds freshen late morning, expect increasing surface chop, particularly at open headlands.
Water remains comfortable at 23°C. Standard summer exposure protection is ideal. With good visibility, this is a great day for photographers and divers wanting to explore deeper sections of the reef.
Safety: Keep an eye on the sky later in the afternoon as showers or storms may develop inland and move toward the coast. If winds strengthen beyond forecast, stick to protected entries and reassess conditions before entering.
Weekend Outlook
The weekend looks generally favourable with small swell and warm water, though wind direction will be the main deciding factor each day.
Weekend Conditions at a Glance
- Weather: Northerly winds Friday. Weak southerly change possible Saturday. Fresh N–NW winds Sunday.
- Swell: Saturday ~0.5 m ENE; Sunday ~0.5 m SSE
- Likely Best Sites: The Steps, Oak Park, and protected entries at Bare Island.
Weekend Diving Outlook
Saturday’s small 0.5 m ENE swell is manageable but may wrap into some southern sites depending on wind direction. Choose protected entries and time dives around slack tide.
Sunday’s 0.5 m SSE swell should be comfortable for most southern shore dives. However, fresh northerly winds may create surface chop on more open sections, so earlier dives are recommended.
Safety: Wind shifts will be the main variable this weekend. Assess conditions on arrival and choose the most sheltered option for the day.
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.
