The Lowdown
G’day, Rusty here. Let’s check the outlook for Windang Island. It’s a reef and point break and it’s open to swell coming from the southeast, which is its best angle. Water temp is pretty normal for this time of year, nothing unusual.
For the next week or so, it’s pretty quiet. From Sunday the 16th through to Sunday the 23rd, there’s almost nothing worth paddling out for. Small slop, cross-onshore winds, and weak energy. The only half-decent moment is Tuesday the 18th morning when it goes glassy – but with the swell only about 3ft and energy weak (121), you’re just playing with tiny waves.
Then Monday the 24th shows up as the first real bright spot. We’ve got a clean 4ft NE swell, with a gentle offshore wind from the WNW making it glassy and clean. Energy is moderate at 222. The period is short at 7 seconds, so it’ll be a bit lumpy, but on a reef and point, that offshore makes a huge difference. Crowds can pop up sometimes, but a Monday should keep it quiet.
Tuesday the 25th is similar with 3ft NE and offshore winds – worth a look but nothing special.
Then we hit a rough patch Wednesday 26th and Thursday 27th – strong southerlies and tiny surf.
But Saturday the 29th is the big one. The morning is glassy with a solid 7ft NE swell. That’s a big wave – energy is strong at 755. Period is 8 seconds, so it’s short-period groundswell, but at that size on a reef and point break, it’ll be powerful and punchy. That’s experts only, way too big for beginners. If you’ve got the skills, this is the session.
Sunday the 30th settles to clean 3ft to 3ft, glassy in the morning. Still fun.
Monday the 31st drops right off again with tiny 2ft waves and no energy.
So to wrap it up: the first week is mostly a dud except for Monday the 24th. The real standout is Saturday 29th August – that’s two weeks out, so it’s a bit of a gamble, but if it holds, that’s the day to be 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.
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.
