The Lowdown
Alright, gather 'round. Rusty here, and I've been chewing on the forecast for our local zone. It's a real mixed-up picture for the next couple of weeks, but there are a few moments that'll make it worth paddling out.
Most of the time, it's looking pretty average, but the one spot that keeps popping up is Windang Island. It's a reef and point break, so when conditions align, it's a proper wave. The water temp is sitting at about 18°, which is nothing special for this time of year.
Right now, it's a slow start. Tuesday the 25th's afternoon is weak with a 5ft north-easterly swell and a cross-breeze making things a bit messy. Then we hit a real quiet patch. Wednesday the 26th is a total write-off, and Thursday the 27th is only marginal with a 6ft south swell but cross-shore winds ruining the shape. Friday the 28th is more of the same.
But hold on. Come Saturday morning, the 29th, things get interesting. We've got a clean 4ft swell from the south-southeast, but the wind is zero – dead glassy. For a reef and point, that's as good as it gets. The combined energy is moderate (448), but the total lack of wind will make every wave feel like a million bucks. That's your weekend session right there.
After that, we're back to a long, flat, and blown-out stretch. The end of August and the start of September is a real dead zone.
Now, for the long-range punters, check out Monday the 8th of September. By the afternoon, the energy picks up to a moderate level (245) with a 6ft south-south-east swell. The good news is a clean, moderate offshore breeze from the west. The swell period is a short 6 seconds, so it's not a groundswell, but that offshore wind will still make it fun. Mark it in the calendar, but remember, it's a long way out.
So, the verdict: Saturday morning, 29th August is your best bet for clean, glassy waves. Monday, 8th September is a promising prospect for a proper session. For everything else, you might as well save the wax.
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.
