The Lowdown
Alright, Rusty here. Let’s break it down for Windang Island over the next couple of weeks.
It’s a slow start. Tuesday, August 11th is where it first picks up. Tuesday morning is poor – just 2ft of south swell and messy. But Tuesday afternoon? That’s the one. Clean 5ft south swell, offshore wind out of the WNW, and a solid energy pulse. That’s your best early session – real good quality waves on offer.
Wednesday the 12th stays clean with 3ft south swell but weaker energy. Thursday is smaller and nothing special. Friday the 14th is glassy but weak – only 3ft swell and not much push.
From Saturday the 15th through the middle of the next week, the wind goes bad – onshore and choppy. The surf stays around 5ft but it’s a mess. Not worth your time.
There’s a dry spell for a few days, but then Saturday the 23rd of August shows a clean 4-5ft ENE swell with cross-off wind. It’s a bit marginal, but if you’re desperate, it’s the only game in town.
Then Tuesday the 25th of August is the real standout. Tuesday morning brings a powerful 8ft south swell with very strong energy – that’s expert territory only. Offshore wind keeps it clean. Tuesday afternoon drops to 6ft south swell but still clean and forecast to be very good. That’s the session to aim for.
Water temp is about 68°F – pretty normal for this spot this time of year. Crowds can show up at Windang Island, so expect company on the good days.
Rusty out.

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.
