The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe.
Honestly, looking at the whole 16-day picture, it’s a bit of a slow burn. We’ve got a long stretch of small, wind-affected stuff before a real pulse of energy shows up late in the game. For the first week and a half, you’re mostly looking at small waves and tricky winds, so patience is the name of the game. The real standout is that last weekend, and it’s a big one, so mark your calendars.
The only spot on offer is Windang Island, a reef and point set-up that's fairly consistent. It's exposed to the swell, but we're dealing with some funky conditions for a while.
Starting off Tuesday the 18th, it’s pretty grim. We’ve got a tiny 1.3ft swell from the ESE, and a cross-onshore wind is messing it all up. The water temp is sitting at a pretty average 64.6°F for this time of year. Don’t even bother paddling out.
Wednesday the 19th sees a bit more size, up to 3.9ft from the E, but the wind swings around to a moderate cross-onshore from the NE at 15.5 mph. It’s gonna be a choppy mess, with moderate wave energy (405). Not worth it.
Thursday the 20th morning is still tiny and cross-shore. The afternoon actually cleans up nicely with a light cross-offshore breeze from the NNW and clean conditions, but the swell is only 2.6ft from the NE with a short period of 6 seconds. It's surfable, but very ordinary. The wave energy is weak (79).
Friday the 21st through to Tuesday the 25th is a real slog. We’re talking tiny waves, mostly below 2.3ft, and inconsistent. The winds are all over the place, but the energy is consistently weak. There’s a brief moment on Monday the 24th afternoon where it goes glassy, with 1.6ft waves from the S at 10 seconds, but it’s just too small to get excited about.
You’ll be waiting nearly two weeks for anything with real grunt. Then we get to Saturday the 30th of August. Now we're talking. Overnight a solid groundswell pushes in. Saturday morning we’ve got a solid 7.2ft swell from the SSE with a very long period of 18 seconds. The wave energy is massive, coming in at 4094. The wind is light and variable from the S, keeping it clean with just small ripples. This is serious size though – over 8.2ft on the afternoon, so this is strictly for experienced surfers only. The point break setup at Windang Island should handle that long period well, but that's a lot of water moving.
The swell hangs around through Sunday the 31st and Monday the 1st of September, but it drops off and the winds get messy again. The best and cleanest window is that Saturday morning. That’s the one.
So, to keep it simple: the next week and a half is a write-off. Don't bother. Gear up for that last weekend of August. Saturday the 30th morning at Windang Island is your only true standout – a big, clean groundswell with some serious power. It’s a promise this far out, but a good one.

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.
