Alright boys, Rusty here, and I’ve been squinting at the charts for this stretch of coast. It’s a slow cook, but there’s a couple of moments where it comes together before the tap gets turned off.
We’re looking at a pretty flat start. Forget Thursday the 3rd – it’s ankle-biters. A 2ft south swell with barely any energy, reading about 79 on the juice meter. The wind is there but it’s not doing much for the shape.
Things get interesting on Friday morning the 4th. At Windang Island, we’ve got a 3ft south swell rolling in, and the wind goes dead glassy. That’s the ticket. On a reef and point set-up, dead calm air means you’re getting clean, peeling lines that nobody else is on. The combined energy is up to 184, which is a moderate push for the size. It’s marked as “fairly consistent,” so you might have to sit and stare a bit, but when they come, they’ll be worth the paddle. The water temp is about right for the season, nothing too crazy.
That glassy spell is short-lived. By Friday afternoon, a light breeze from the wrong direction chops it up.
Now, Sunday the 6th is the one to circle on your calendar. The morning session is clean again with a light cross-off airflow. The swell is a solid 4ft from the south, with a 11-second period, and the energy jumps to 359. That’s a proper moderate pulse. The direction is just about perfect for this spot. You’re looking at clean, shoulder-to-head-high runners. This is the standout session of the whole 16-day run.
Monday the 7th has some leftover energy, still around 4ft and clean in the a.m., but the wind shifts and the quality drops off quick. Tuesday the 8th sees a bigger bump to 6ft from the SSE, but with a short period of 8 seconds. The energy is beefy at 425, but it’s going to be a lumpy mess by the afternoon. That’s expert territory or kite-surfing conditions only.
From Wednesday the 9th onward, it’s a long, quiet stretch. We get a few days of waist-high swell, but the wind never plays ball. It’s all cross-onshore or just messy. After the shine from the 6th and morning of the 7th, there’s a dead zone of poor quality from the 9th all the way to the 18th. There’s a flicker on the 17th with a clean 4ft south swell and offshore wind, but it’s two weeks out so don’t hold your breath.
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.
