The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Windang Island.
First up, the water temp is sitting at about 64°F, which is pretty much normal for this time of year, so no nasty surprises there.
Honestly, the start of this outlook is a bit of a struggle. Friday morning on the 28th of August is the best we see for a while – we’ve got a clean 5 ft swell from the SSE with a light cross-offshore breeze, and the combined energy is a solid moderate 597. That’s your best bet early on, but by the afternoon the wind swings and chops it all up.
From Friday afternoon all the way through to the morning of Monday the 7th of September, it’s a long, dry spell. There’s really nothing worth getting wet for – just small, weak, and messy conditions with combined energy dropping from moderate right down to a weak 32. You’re looking at over a week of flat and ordinary surf.
Now, Monday the 7th of September is where things wake up. The morning brings a clean 6 ft swell from the south with a solid offshore breeze. The combined energy jumps to a strong 617, and the conditions are described as “very good.” This one’s a standout for the more experienced crew – it’s not beginner-friendly at that size.
But the real star of the show is Tuesday the 8th of September. We’ve got a clean 5 ft swell from the SSE but the period stretches right out to 15 seconds – that’s proper long-period groundswell. The combined energy is huge at 2518, and the wind is light and cross-offshore. This will be firing for experienced surfers, but that long period means it might be a bit too straight for the beach – point breaks and reefs will handle it best. Expect it to be clean, powerful, and quality.
Wednesday the 9th still looks solid with 7-7 ft SSE swells, but the wind is cross-shore and there’s some rain around. It’s still big, but not as clean as Tuesday. By Thursday the 10th, it’s dropping off and getting messier.
So to keep it simple: Tuesday the 8th of September is the day to circle on the calendar. Get ready for a proper autumn groundswell with clean conditions at Windang Island. The Monday prior is also a solid fallback. Everything else in this 16-day window is a write-off.
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.
