The Lowdown
Alright, Rusty here, let’s have a look at the outlook for Windang Island.
Right off the bat, we’ve got a bit of a slow start, but things start to shape up. The first real standout is Friday morning, September 4th. It’s not big, but it’s clean. We’re looking at a 3ft south swell with a period of 10 seconds, pushing a moderate 213 units of energy. The wind is glassy, coming straight out of the west at just 3 mph. That’s the kind of session where you can get a few smooth ones at the reef and point, feeling the water at 64°F which is about average for this time of year. It’s a fairly consistent spot, but it can get crowded sometimes, so get in early.
After that, things get a bit messy. Saturday and Sunday are small and junky, so not worth paddling out for. Monday morning, the 7th, sees a bump in swell to 4ft from the south, with a period of 8 seconds and 182 units of energy. The wind is light and clean, so you could get some functional waves, but it’s nothing to write home about.
Now, the real meat of the forecast starts to appear on Tuesday, September 8th. The morning shows a solid 7ft swell from the SSE, with a 10-second period and a strong 776 units of energy. The wind is clean and cross-off, so the reef and point will be handling that size well. It’s getting into the territory where beginners might want to sit it out, as it’s over 5ft. The afternoon jumps up to 7ft and over 1000 units of energy, but the wind switches onshore, making it a bit of a mess.
The best session on offer, and the one I’d be circling, is Thursday, September 10th. The afternoon is pumping a 10ft groundswell from the south, with a period of 12 seconds and a massive 4851 units of energy. That’s a serious amount of power. The wind is moderate cross-shore, so it’s not perfect, but for a spot like Windang Island, that’s a heavy, expert-only wave. The period is long, so the sets will have plenty of push and the lulls between sets will make it easier to get out the back. If you’re not an advanced surfer, this is a day to watch from the shore.
The following week has a few pulses, but nothing that stacks up to that Thursday. There’s another spike on Thursday, September 17th. The afternoon looks incredible on paper: a 10ft south swell, 12-second period, 3364 units of energy, and glassy offshore wind from the west at 6 mph. That’s a combination that has "excellent" written all over it for experienced surfers. It’s a long way out, so it’s a promising call, but not set in stone.
The final days of the outlook stay big but get messy again with cross-shore winds and lumpy conditions, so for the best of the best, aim for those Thursday sessions.
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.
