The Lowdown
G’day, Rusty here again. Let’s run through the same outlook in feet and miles, so you’ve got the full picture.
Right now, things are pretty flat and average, so you’re not missing much. The first real window of surf kicks off Sunday the 10th of August at Windang Island, but honestly, it’s more of a tease than anything solid—waves around 6 ft from the ENE with a short 9-second period, and while the cross-offshore wind from the NNW will keep things clean, the energy reading of 591 is only moderate. The swell drops back Monday the 11th, with a cleaner, better-shaped pulse from the south. Tuesday the 12th, morning glass-off conditions with a 3 ft south swell at 11 seconds and a gentle offshore from the WNW. That’s a nice clean start to the day, with a moderate wave energy reading of 232. That same day, Wednesday the 13th, Thursday the 14th, and Friday the 15th all have some clean windows with offshore wind, but the swell sizes hover around 3 ft to 4 ft—still fun for a longboard or a fish, but nothing that’ll have you scrambling for the wetsuit. Thursday the 14th of August, Friday morning is the pick of this run: glassy conditions, a solid 4 ft south swell at 9 seconds, and clean waves. Energy sits at 333 (moderate), and with light WSW winds, it’ll be well-shaped.
Now, the real standout—the one to circle on your calendar—is Thursday the 20th of August. Early morning, Windang Island will be firing with a 6 ft ENE swell at 9 seconds and a clean cross-offshore wind from the SSW. The combined wave energy reading hits 797, which is solidly moderate-to-strong, and it’s looking like the best conditions of the whole outlook. The swell direction from the ENE works well with the reef and point setup here, which is exposed to SE swells. Expect good quality, longer-period energy with clean faces. Crowds are possible here—it’s a well-known spot—but the quality of the surf will be worth it. The water temperature is around 65°, pretty much average for this time of year with only a slight anomaly of 1°, so nothing unusual.
The week leading up to the 20th has a few days with swell over 5 ft, like Tuesday the 19th with 5 ft ENE at 8 seconds, but the onshore wind and short period make it sloppy and better suited for experts—or maybe even kite surfers if you’re into that. Saturday the 22nd and Sunday the 23rd both have clean morning windows with 6 ft to 6 ft ENE swell, long 10-second periods, and offshore winds, but the energy is only moderate. A good backup, but not the main event.
All up, the 16-day window has a few decent days, but Thursday the 20th of August morning at Windang Island is the one to aim for. Don’t sleep on it.
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.
