The Lowdown

G’day, Rusty here. Let’s break down what Windang Island has on offer. We’ve got a dead stretch right off the bat – from Saturday the 12th through Tuesday the 15th, that’s four straight days of poor, messy surf. Small, cross-onshore chop, nothing to get excited about. Water temp is about 18°, which is normal for this time of year.

Then things finally wake up. Wednesday the 16th sees a jump to 8ft of southerly swell, with energy hitting 1186 – that’s a serious pulse. The morning has a cross-offshore wind, so the waves will be clean, but the south wind is blowing 30 km/h and the period is 9 seconds, so there’s some bump. This is expert-only – 8ft is too big for beginners. Thursday the 17th is similar, 8ft again, with a lighter cross-offshore breeze in the morning, keeping it clean. Swell energy is 1109. Those two mornings – the 16th and 17th – are the clear standouts. If you’re skilled and keen, that’s your window.

By Friday the 18th, the swell drops to 3ft, glassy in the morning with a light east-northeast breeze, but the waves are just ordinary. Then we sink into a huge gap from Saturday the 19th all the way to Sunday the 27th – nearly a week and a half of tiny, weak, or onshore junk. The only glimmer is Friday the 25th, with 2ft to 3ft and glassy conditions, but again, just ordinary waves. Not worth the paddle.

Bottom line: save your energy for Wednesday and Thursday mornings the 16th and 17th. That’s where the real action is – solid 8ft southerly swell, clean, powerful, and all for the experts. After that, it’s back to the doldrums.

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.
