The Lowdown
G’day, Rusty here. We’ve got a real mixed bag coming up at Windang Island over the next couple of weeks. The window for good, clean waves is tight, so you’ll want to pick your moments. The water temp is sitting around 64°F right now, which is pretty much normal for this time of year.
The first real standout is Tuesday afternoon, August 11. A solid 6ft swell rolls in from the south with an 11-second period, packing moderate wave energy (764). That’s a nice groundswell, and with a moderate westerly offshore wind it should be clean and lined up at this reef and point setup. That swell direction is not quite the optimum SE, but it’s close enough to produce some proper waves. It’s an advanced break and fairly consistent, so expect a few others in the water – sometimes crowded, but worth it for the quality on offer.
Friday morning, August 14, is your next good look. Smaller at 4ft from the south with a 9-second period, but the wind is dead glassy – slight air, no chop. Wave energy is low-mod (211), but for clean, smooth conditions on a point, that’ll be fun and forgiving. This one’s for the patient surfer who wants a long session without the battle.
After that, things get patchy. There’s a run of poor quality through the middle of the second week, but things perk up again going into Sunday morning, August 23. Another glassy start with a 4ft ENE swell running at 10 seconds – moderate energy (264). The direction is a bit off the optimum, but with no wind and clean conditions, it’ll still be surfable. Then Monday morning, August 24, brings a clean 4ft ENE groundswell with a light cross-offshore WSW breeze. That’s a promising end to the outlook, but we’re talking over a week away, so treat it as a hopeful maybe.
A couple of caveats: the bigger 6ft Tuesday session is for advanced crew only, and the longer period swells later in the run might suit the point more than a beach break. There’s a few days with poor surf quality and stronger winds – not worth paddling out for. Overall, keep your eyes on Tuesday the 11th and Friday the 14th; those are your best bets.
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.
