The Lowdown
G’day, I’m Rusty. Let’s talk about Windang Island. This reef and point setup needs the right swell direction to fire. Over the next 16 days, the first week is flat to tiny, then we get a big pulse in the second week that’s only for the experienced.
Right now, the surf is marginal. On Saturday the 29th, there’s a 4ft SE swell at 10 seconds, but the wind is cross-shore or onshore, and the total wave energy is weak at 387. Sunday the 30th through to Tuesday the 1st of September stays poor, with swell dropping to 3ft – 3ft from the S, energy in the 140s to 170s, and poor wind. Wednesday the 2nd cleans up a touch with a light offshore wind, but the swell is only 2ft at 10 seconds – just barely surfable. Thursday the 3rd and Friday the 4th go flat, with swell down to 1.0ft – 2ft and energy below 70. Saturday the 5th and Sunday the 6th are poor, with a short-period windswell of 4ft but only 7 seconds.
Then it gets real. On Tuesday the 8th of September, a big swell arrives. The morning has 12ft from the S at 9 seconds, with strong energy (2090) and light cross-shore wind – but it’s marginal. The standout is Tuesday afternoon: 12ft from the SSE at 11 seconds, with glassy wind. The energy jumps to 3164 – that’s very strong. This is a long-period groundswell, so on a point break it will produce powerful, well-shaped sets. But at 12ft, this is for experts only. Wednesday the 9th stays big with 7ft to 10ft from the SSE at 10 seconds, energy over 1400, and clean but strong cross-offshore wind. Thursday the 10th has 7ft but fresh winds making it rough. Friday the 11th morning cleans up with 5ft from the SSE at 10 seconds, glassy conditions, and moderate energy (440) – a good session for experienced surfers. After Friday, the swell fades into the weekend with smaller 4ft stuff and onshore wind.
The best day is Tuesday the 8th of September afternoon at Windang Island. Huge, clean, glassy SSE groundswell with very strong energy – a proper session for big-wave chargers. Crowds are sometimes an issue here.
Water temp is about average for the time of year.
This is Rusty, signing off.

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.
