The Lowdown
Alright folks, Rusty here. We’ve got a 16-day look at what’s on offer, and it’s a bit of a mixed bag. We’re starting with a few days of nothing worth paddling out for, so expect a gap before things get interesting.
The first real session to point the board at is Monday the 7th of September. Windang Island is waking up with a glassy, clean morning. The swell is a modest 1.4m out of the SSE, and with the wind dead flat (NE 5 km/h), the surface will be like a mirror. The combined energy is moderate (256), so there’s enough push for a fun session. This is the standout of the early run. The water temp is about average for this time of year, so not a drama.
The afternoon shifts on Monday though, with a cross-onshore wind making things a bit choppy.
Tuesday the 8th sees a jump in size – 2.0m to 2.1m from the SSE – and the energy is strong (888). The mornings are cleanish with a light cross-shore, but the afternoons get messy. This is getting into the territory where it’s a bit much for beginners, but still workable for the average crew.
Wednesday the 9th and Thursday the 10th are a write-off. Strong winds and lumpy, poor conditions. The swell sticks around 2.0m-2.1m, but the combo of wind and chop makes it a no-go for paddle surfing. Honestly, if you’re into kite surfing, those Thursday morning cross-off winds and that size might look tempting.
The next real standout pops up way down the line on Tuesday the 15th of September. Windang Island serves up a glassy morning again with a 1.0m SSE swell. Wind is completely calm (NW 0 km/h). The energy is moderate (221), and the sets will be clean and lined up. It’s a smaller day, perfect for a relaxed longboard or a mid-length. This is the best of the second week, but it’s a long way off, so keep an eye on the forecast.
After that, the outlook fades again with small, weak swells and onshore winds through the end of the window. Nothing else really jumps out as a must-surf.
So, to sum it up: Monday morning the 7th is the pick of the early run, and Tuesday the 15th is a promising but distant possibility. The rest is a waiting game.
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.
