The Lowdown
G’day, I’m Rusty. Let’s talk about what’s brewing for Windang Island. This is a reef and point setup, exposed to the south-east, and it’s an advanced break that’s fairly consistent. The water’s sitting at 64°F right now, which is about average for this time of year – no big deviations.
The first week or so is a slow starter. From Monday the 31st of August through the first few days of September, it’s all small, ordinary surf with weak energy – the combined energy’s barely hitting 100 to 250 (172 to 253) and the swell’s stuck around 1ft to 3ft from the south. Winds are a mix of cross and cross-off, but the waves are just too small and weak to get excited about. There’s a gap of several days here with no real recommendations – it’s a bit of a dry spell.
Then, on Sunday the 6th of September, things pick up. The morning brings a glassy surface with a 4ft south swell, period around 9 seconds, and the combined energy jumps to 244. The wind is glassy, so it’ll be clean and smooth. That’s a decent little window – the best of this early stretch, but it’s not a standout.
Now, the real action’s in the second week. Wednesday the 9th of September sees a huge spike: a 15ft swell from the SSE, period 10 seconds, and the combined energy is absolutely thumping at 4801. That is strong, very strong energy, but it’s too big even for this advanced break – it’s predicted to be too big, so keep the board on the sand unless you’re a total charger or you’re looking at kite surfing conditions.
The true standout, the one to circle on the calendar, is Thursday the 10th of September. The morning session is where it’s at: glassy conditions, an 12ft swell from the SE, period 10 seconds, and combined energy at 2326. That’s a solid, powerful groundswell, and the wind is glassy – it’ll be clean and lined up. This is excellent surf for experienced surfers, and it’s the best on offer. The crowd profile at Windang Island is sometimes busy, so with a window like this, expect company.
After that, through Friday the 11th and into the weekend, the swell drops to 5ft to 6ft from the east, but the wind turns onshore, so it gets chopped and messy. The energy stays moderate (around 394 to 633), but the conditions just aren’t there. The following week, from the 13th onwards, fades into small, weak south-east swell with onshore winds – not worth paddling out for.
So, bottom line: the first week is a write-off. Sunday the 6th gives you a tiny glassy window, but the real standout is Thursday the 10th of September morning – that’s the one to chase. It’s a long-range call, so keep an eye on it, but it’s promising.
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.
