The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for Windang Island over the next couple of weeks.
Right off the bat, we’ve got a bit of a slow start. The surf over the first few days is pretty ordinary, with some small, short-period, wind-affected junk. The water temp is sitting at 64°, which is pretty much average for this time of year, so nothing to write home about there.
The first real standout comes on Tuesday, the 8th of September. We’re looking at a solid 8 ft swell from the S, with a period of 9 seconds – that’s a decent amount of power, with a combined energy of (2192) pushing through. The wind is a clean cross-off from the SSW, which is going to keep the face of that reef and point setup pretty tidy. This is serious ground for experienced surfers only – that size is well into the expert zone. It’s not a spot for the groms.
Then, on Thursday morning, the 10th of September, the swell bumps up to 10 ft from the S, with a 10-second period. That’s a massive amount of energy, hitting (3027). The wind is light from the S, so it’s a cross-shore breeze, keeping things semi-clean. Again, this is for the big-wave crew only. The crowd factor here is "sometimes", so you might get a crew out, but it’s worth the paddle for the wave quality.
The second week looks a bit more inconsistent. There’s a promising window on Monday afternoon, the 14th of September, with a 4 ft SSE swell and a 11-second period. The wind swings offshore from the WSW, which is a great sign. Energy is moderate at (340), but the wind is clean, so the conditions could be fun for a more relaxed session.
We also see a return of some size on Tuesday morning, the 15th of September, with another 10 ft S swell (2713), but the wind is a light cross-on from the SE, which will put a bit of texture on the face. It’s a heavy day again, but the wind is a slight negative.
The rest of the period fades out into small, weak, and often wind-affected surf. There’s a few days in the final week with offshore winds on tiny swells, but you’ll be scratching for a ride.
So, in short: the best bet is the Tuesday morning, 8th of September, for the clean, powerful swell. If you’re a real charger, Thursday the 10th morning is also a belter, but the wind is a touch less perfect. The later part of the period is a gamble for anything decent.
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.
