The Lowdown
Alright, Rusty here again. Let's break down the outlook for Windang Island. The first few days are pretty much a total loss for decent surf.
Tuesday, August 25th, starts off with a weak 3ft ENE windswell, but a north breeze chops it all up. Totally un-surfable. Wednesday doesn’t offer much better with more poor conditions and crossed-up winds. Thursday, August 27th, sees a bigger SSE swell build to 6ft, but it’s onshore with wind bumps; the combined energy indicates a moderate pulse, but it won't be clean.
That changes Friday morning, August 28th. The wind goes light cross-offshore, cleaning up a 5ft SSE groundswell with a nice 11-second period. The wave energy is solid (620) and conditions are clean. That’s the first real window. Be on the water early, because the quality drops off fast that afternoon.
Saturday, August 29th, pushes up a 7ft southerly swell – that’s expert territory – and the crossing wind makes it messy. Sunday the 30th offers a quick reprieve: glassy conditions and a clean 4ft southerly groundswell. A nice relaxed paddle for those with experience on a reef/point.
The next week is patchy. Monday, August 31st serves up a tiny 2ft swell with a super long 18-second period. That long period can make it fat at the beach, but on a point it might give some clean, drawn-out lines – if the size holds. Risky. Tuesday, September 1st has clean 3ft SSE waves with light offshores – easy, clean little peelers. But then it goes small again.
The big highlight is Thursday, September 3rd. That’s the one. A 20-second period SSE groundswell at 5ft with glassy conditions. The wave energy is huge at 1687 – that's a powerful code. The afternoon goes even better: still 5ft but with a light offshore wind and clean lines. This is excellent, heavy water for the experienced crew. That’s the session to target.
After that, it fades into smaller, onshore days, though Saturday, September 5th still has some 6ft SSE swell, but a north cross-breeze makes it lumpy. Lock in Thursday the 3rd as the absolute best.
Stay sharp, and I'll see you out there.
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.
