The Lowdown
Grab a coffee and let me take you through the next couple of weeks at Windang Island. This is a call for the patient ones, with a couple of real gems hidden in the back half.
The first real surfable window opens up on Wednesday morning, the 12th of August. It’s not a massive day, but we’ve got a 3 ft south swell pushing through with a 9-second period. The big plus here is the solid offshore wind from the WNW at 9 mph, which should keep the lines tidy. The water temp is about average for this time of year, nothing to write home about. The energy is moderate (218), so it’s a fun little session for the advanced crew – this is a reef and point set-up, so you need to know what you’re doing. That morning is your best bet, as the afternoon sees the swell drop to 3 ft and the wind picks up. Thursday morning is similar, with a clean 3 ft south swell, but again, it’s a small window before the wind swings onshore.
From Friday afternoon right through to the end of the following week, things get pretty ordinary. A lot of weak, short-period wind swell, onshore winds, and rain. There’s a solid 5 or 6-day gap where you’d be wasting your time in the water. The energy is low to moderate, and the conditions are just messy.
There is a real standout, but you have to wait for it. On Saturday, the 22nd of August, the morning session looks clean. We’ve got a 5 ft ENE swell with an 11-second period – that’s proper groundswell, long lines and good energy. The wind is a light cross-offshore from the NW at 6 mph, so the face will be clean. The energy is strong (496), so there’s some push. This is a good one, but for a break like this, a longer period swell can sometimes run a bit straight, so you’ll want to pick your peak.
Hold onto your board, because Wednesday the 26th of August is the big one. The morning session is a serious standout. Glassy conditions, 3 mph wind from the south, and a solid 13 ft south swell with a 10-second period. The energy is massive (2874), and the conditions are glassy. This is an expert-only day – that’s big, powerful swell on a reef and point. It’s not for the faint-hearted, but if you’re a seasoned surfer, this is the best on offer in the whole 16-day window. The afternoon gets a bit messy with onshore wind, but that morning will be etched in the memory.
Thursday the 27th still has a chunky 8 ft south swell, but it’s a bit messy with a cross-shore wind. Still worth a look if you missed the peak.

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.
