The Lowdown
Alright, folks, Rusty here. Let's have a good look at what Windang Island has got cookin' for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – the start of this run is a bit of a tease. We've got some size on the way, but the wind is just all wrong. The first few days are a write-off for any decent surf. We’re looking at a couple of days of cross-shore and onshore junk, with lumpy conditions. It's not gonna be pretty.
The first real flicker of hope shows up on the morning of Thursday the 10th of September. The wind is clean and the swell is pushing 10ft from the south. Now, that's a big, meaty wave with moderate energy (2859). This is only for the experienced crew; beginners, stay on the sand. That kind of size out at a reef and point setup will have some serious power.
But the real standout, the one you've been waiting for, is Sunday the 20th of September. The forecast is for a solid 7ft southerly swell with a period of 11 seconds, pumping in a good amount of energy (1060). And here's the kicker – the wind is set to be glassy, dead calm. That is as good as it gets for clean conditions. This is going to be an excellent session for those who know what they're doing. The water temp is around 64°, which is pretty average for this time of year, so no surprises there.
The afternoon before that, on the 19th, is also worth a mention. We've got a clean, offshore wind from the west and a 3ft swell from the SSE. That's a much smaller, more manageable wave, but the wind will make it fun for anyone. The crowd factor is listed as "sometimes", so it could get a little busy, especially with conditions that good.
Looking further out, Monday the 21st of September drops right back off, with small, weak waves and poor conditions. So really, the window is that weekend.

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.
