The Lowdown
Alright, Rusty here with a look at what’s on the cards for the next couple of weeks.
We’re starting off a bit slow, but there’s a couple of solid windows to get excited about, especially if you’re an advanced surfer. The water temp is sitting at 64°F, which is pretty standard for this time of year.
The first real standout is Thursday morning, August 27th. Windang Island is looking clean with a solid 6 ft swell rolling in from the south, period of 9 seconds. The wind is light and cross-off, so the surface will be nice and clean. The combined swell energy is sitting at 615 (moderate), so there’s plenty of push. This is a good one for the advanced crew.
Then, Friday morning, August 28th, is another cracker. We’ve got a 5 ft swell from the SSE, but the period jumps to 11 seconds, giving it more shape and power. The wind is light and cross-off again, keeping it clean. Swell energy is 607 (moderate). This is a groundswell, so it’ll have some good lines, especially for a reef and point setup like this.
After that, things drop off a bit. Saturday the 29th has some decent energy (1056 – strong), but the wind is cross-shore and the conditions are a bit mixed. The rest of the week into early September is small, mostly under 3 ft, with light winds. There’s a bit of a lull here for several days.
Now, fast forward to Monday, September 7th. The morning sees a 7 ft S swell with 11-second period and moderate cross-off wind, but it’s marked as marginal. The afternoon, though, is the real story: 6 ft from the SSE, 13-second period, and the swell energy is massive at 1254 (very strong). The wind is light cross-on, so it won’t be perfect, but the size and power will be there for experts only – this is a serious paddle.
Into Tuesday the 8th, the morning has a 4 ft S swell with 11-second period and glassy conditions – clean and inviting. Swell energy is 423 (moderate). A nice option if that Monday is too big.
Finally, Thursday morning, September 10th, sees a 5 ft S swell with 10-second period, light cross-off wind, and clean conditions. Swell energy is 501 (moderate). Another solid all-rounder.
Overall, the best windows are Thursday and Friday mornings this week, and the big Monday/Tuesday window next week for the advanced crew. Keep an eye on the forecast for that one.
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.
