The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Windang Island.
The next couple of weeks are a bit of a mixed bag, but there’s a serious pulse of energy on the horizon for the brave among us. We’ve got a solid wait for the real action, but it will be worth it for the crew that can handle it.
We kick off on Thursday morning, 27 August. Windang Island is serving up a solid 7ft of south swell with a 9-second period. The combined energy is pumping at 1228, so there’s plenty of push. The wind is a light cross-off from the SSW at 6 mph, and it’s clean. The water temp is 64°, which is about average for this time of year. This is excellent surf for experienced surfers – it’s got some size and power, but it’s not for the faint-hearted. That 7ft is getting into the territory where it’s a bit much for beginners.
Thursday afternoon fades a bit, and Friday morning (28 August) brings a drop to 5ft from the SSE with a longer 11-second period, good energy at 661. The wind is still light cross-off, so it’s clean. That’s a very good window for those who want a bit of quality without the full-on Thursday size.
Saturday and Sunday (29-30 August) see the swell drop off. Saturday is small, around 4ft, with light cross-onshore winds – not great. Sunday morning, 30 August, is the pick of the weekend: a clean 3ft of south swell, and the wind goes glassy. It’s small, but for a log or a fun board, it’s a dream. The energy is low at 209, but the conditions are pretty.
Monday and Tuesday (31 Aug – 1 Sep) are small and messy, with onshore winds and choppy conditions. Not worth paddling out for. Wednesday (2 Sep) through to Thursday (3 Sep) are tiny, with waves barely hitting 1ft. The wind is offshore, but there’s nothing to ride. This is a lull.
Friday (4 Sep) has a tiny 3ft NNE swell with a short 6-second period, so it’s weak and sloppy. The weekend of 5-6 September is similarly poor, with small swell and strong winds. The week of 7-9 September is a write-off for any real surf. There’s a gap of about 8 days where the surf is basically non-existent.
Now, here’s the standout. Look to Wednesday, 9 September, through Friday, 11 September. On Wednesday afternoon, the south swell jumps to 8ft, with a combined energy of 1274. But the wind is a strong cross-shore, making it lumpy and marginal. The real gem is Thursday morning, 10 September: a solid 8ft south swell, 12-second period, and a combined energy of 3426. The wind is a moderate cross-off, and it’s clean. That’s a powerful, well-shaped groundswell. This is for experts only – over 8ft, it’s a serious session. The long period (12 seconds) means it’ll be better lined up on the reef and point, which is exactly what Windang Island is.
Then, Friday morning, 11 September, is the absolute standout. The swell is 10ft from the SSE, with a 12-second period, and the combined energy is 2102. And the wind? It’s glassy. Completely glassy. For a reef and point break, that’s as good as it gets. The sets will be big and powerful, with long lulls between them. This is an epic morning for the experienced crew only. The wind stays clean all morning, but by Friday afternoon the onshore kicks in and it gets messy.
So, to sum it up: the first week is a tease with a few clean windows. The real gold is that Thursday and Friday, 10th and 11th of September. If you’re an expert and you can handle serious size, that Friday morning with glassy conditions is the one to circle. Just be aware that the swell is coming from the south, which is the optimum direction for this spot, so it’ll be hitting the reef and point just right.
Stay safe out there, and don’t forget your wetsuit.
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.

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.
