The Lowdown
G’day, Rusty here. We’ve got a bit of a slow start at Windang Island (reef and point) for the next week or so, but hang in there – there’s a proper pulse lining up for the second week that’s worth getting excited about.
The first solid session lands Friday morning, the 28th of August. The swell is a clean 5ft from the SSE, with a period of 11 seconds – that’s a nice groundswell, plenty of energy (combined energy of 597). The wind is light and cross-offshore from the SSW, so it’ll be clean and lined up. This is the standout of the early window. By Friday afternoon, the wind swings onshore from the SSE at 12 mph and the quality drops off hard.
Saturday the 29th and Sunday the 30th offer small, marginal waves around 3ft to 4ft from the SSE and S, with light onshore or cross-shore breezes. It’s not terrible, but you won’t be rushing. Monday the 31st through to the morning of the 2nd of September is pretty flat and poor, with tiny swell and onshore winds. From the 2nd into the 4th, the swell drops to barely 1ft – glassy conditions on the 4th morning, but there’s just no energy (combined energy down to 27). You’re better off waiting.
Now for the good stuff. Come Sunday, the 7th of September – that’s the Monday morning you’ve been waiting for. We see a solid 7ft swell from the S with an 11-second period, clean off the SW at 16 mph, and the combined energy jumps to 1053 – that’s strong and powerful. This is the true standout of the whole outlook. It’s only for experienced surfers at that size, but the reef and point setup will handle that long-period groundswell beautifully. By the afternoon, the wind shifts onshore and it gets messy.
Tuesday the 8th of September morning is a nice follow-up: 4ft from the S, glassy conditions with no wind, combined energy at 296 – a good clean option for those who missed the Monday morning session. After that, the swell fades fast through the rest of the week into tiny, ordinary surf.
The water temperature is about average for this time of year, nothing wild to report. Crowds can show up sometimes at Windang Island, so keep an eye out if you’re heading there for that Monday morning swell.
Overall, the first week is pretty quiet, but that Monday the 7th of September morning is your best bet – get out there early for the clean, powerful S swell. Later calls for the second week are promising but less certain as always.
Stay stoked,
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.
