The Lowdown
G’day, I’m Rusty, and here’s the look for Windang Island.
Alright, we’ve got a solid run of surf coming up, but it’s got a few rough edges. The water’s sitting at 66°, which is a touch warmer than normal for this time of year – nothing crazy, but you’ll notice it’s a little more comfortable than usual.
The action starts Thursday morning, 30 July. Windang Island is the only spot on the cards, and Thursday morning kicks off with a clean 5ft south swell, 9-second period, with a light cross-off breeze from the SSW. The combined energy is moderate (340), and it’s looking good for a paddle. The morning is the go – by Thursday afternoon, the wind swings to the SSE and picks up to 12 mph, turning it into a choppy mess.
Friday morning, 31 July, is another clean one. Swell holds at 5ft from the south, 10 seconds, with a light SSW cross-off – clean lines and decent energy (484). Friday afternoon gets a bit messy as the wind changes, but the morning is sweet.
Now, Saturday morning, 1 August, is a glassy gem. The swell drops slightly to 5ft from the SSE, 9 seconds, but with a glassy southerly breeze, it’ll be stunning. Combined energy is 342 – not huge, but clean and fun. The standout for the first weekend is Sunday morning, 2 August. We’ve got a 5ft swell from the SE, but the period jumps to 12 seconds – that’s proper groundswell energy. Combined energy is strong (640), and with a north cross-off breeze, it’s clean. This is the best of the first week. Sunday afternoon gets blown out by a strong 16 mph NE wind, so get out early.
Monday, 3 August, the swell drops to 3ft with an 11-second period. Combined energy is weak (142), and while it’s clean, it’s small. The surf is there but ordinary. Tuesday, 4 August, is a write-off – tiny 1ft to 2ft swell and strong offshore winds. Not worth a paddle.
Wednesday, 5 August, glassy again with a 3ft south swell, 8-second period, but it’s weak (141) and ordinary. Thursday, 6 August, is similar – glassy but small and weak. Friday, 7 August, has a bit more energy (226) with 4ft swell, but the wind is up and it’s marginal.
Now, hold on for Saturday morning, 8 August. This is another standout. The swell jumps to 5ft from the south, 8 seconds, but it’s dead glassy – combined energy is strong (594). That’s clean, punchy, and fun. Best session of the second week. The morning of Monday, 10 August, is a bit messy, but Monday afternoon sees a 5ft ESE swell, 12-second period, with a strong offshore west wind at 12 mph – combined energy 537, clean and powerful. That’s a solid wave for the experienced crew.
The following Thursday morning, 13 August, has a clean 5ft south swell, 7-second period, and the energy is moderate (432) – good for a paddle. Friday morning, 14 August, is the last real highlight: 6ft south swell, 8 seconds, combined energy 678 (strong), with a light cross-off – clean and punchy, but that size is getting into intermediate territory.
Overall, the best on offer is Sunday morning, 2 August, with that 12-second groundswell and clean conditions, and Saturday morning, 8 August, for the glassy perfection. Get out early for these.
Rusty.

Information about the Windang Island Surf forecast
The above surf forecast table for Windang Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Windang Island can be found by selecting the local surf guide option on the grey menu. Our Windang Island surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Windang Island) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Windang Island may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Windang Island is 7 km (4 miles) from the city of Port Kembla. If you plan a holiday in Illawarra, look for hotels and other accommodation in Port Kembla. Port Kembla has rooms for a wide range of budgets as well as car hire and transport links.
