The Lowdown
G'day, Rusty here. Look, I'll be straight with you – this 16-day stretch for Windang Island is a pretty ordinary run. There's no big, epic swell window to get excited about, and most days are messy with poor conditions. We've got a few windows that could be alright if you're keen and patient, but don't expect any world-class sessions. The water temp is sitting around 64°, which is just about average for this time of year, nothing unusual there.
Let's start with the first real chance – Wednesday morning, the 26th of August. It's not big, with a 3ft swell out of the northeast, but the wind swings to a light cross-offshore from the southwest, keeping the surface clean. The combined wave energy is weak at 102, so it won't have much punch, but if you want a longboard or a mellow session, it's about the best we see all week.
The next standout is Friday morning, the 28th of August. We get a 3ft swell from the south-southeast with a longer period of 10 seconds, giving it a bit more shape and energy (224 in combined energy). Winds are light cross-offshore from the south-southwest, so it should be clean again. This is another small, user-friendly window.
Now, if you're an experienced surfer wanting a bit more size, look at Saturday morning, the 29th of August. The swell bumps up to 6ft from the south-southeast, with moderate energy at 840. Winds are near glassy from the south at just 3 mph, so it'll be clean with only light ripples. That's the biggest and cleanest combo in the whole outlook, but it's not huge – still manageable for most.
After that, things get pretty flat and ugly. There's a small window Wednesday morning, the 2nd of September with a 2ft south swell, clean with cross-offshore winds, but it's tiny. And then Thursday morning, the 3rd of September brings a 4ft south swell with clean conditions, but the energy is weak. Later that afternoon the wind cranks up to 16 mph, so get in early.
Saturday morning, the 5th of September offers a glassy 3ft swell from the south-southeast with a nice 11-second period – that's the cleanest-looking session in the second week, but still small. After that, it's mostly flat and onshore right through to the end of the 16 days.
Overall, the best session for clean, surfable waves is Saturday morning, the 29th of August – a little bit of size, glassy conditions, and decent energy. Friday the 28th morning is a solid second pick. Everything else is pretty marginal. Crowds might be a factor though – Windang Island can get busy sometimes, so don't expect to have it to yourself.
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.
