The Lowdown

G’day, Rusty here. Let’s talk about what’s coming up for Windang Island. It’s a reef and point set-up that usually needs a decent S to SE swell to light up, and it’s exposed to the open ocean, so it catches most of what rolls in.

Right off the bat, Sunday the 30th of August morning is the real deal to start. We’ve got a clean 3ft S swell, period sitting at 9 seconds, and it’s glassy—wind is only a whisper from the ESE at 3 mph. The combined energy is moderate (223), meaning there’s enough push to get into the waves without it being a battle. The water temp is sitting pretty much average for this time of year, so no surprises there. This is the standout of the near-term. The point should set up nicely with that south swell direction lining up with what the spot wants (optimum from the SE). Crowds can be a thing here sometimes, so get in early.

Monday the 31st morning stays similar—3ft S swell, period dropping a touch to 8 seconds—but the wind is glassy from the ENE at 3 mph. The energy is still moderate (166), and it’s clean, though the shorter period means the waves might be a bit more jumbled and less of that long point-break glide. Still a good session for the patient surfer.

Tuesday the 1st of September afternoon offers a little window: 3ft S swell with a 10-second period, combined energy at 256 (moderate), and a light cross-offshore wind from the NNW at 6 mph. The waves should be clean and have a bit more shape than the morning. After that, the rest of the first week drops off quick—small, fading swell with between 1ft and 2ft through to Sunday the 6th. The winds are mostly offshore or glassy on a few mornings, but the wave height is too small to get excited about. A few sessions are surfable, but nothing to write home about.

Now, looking into the second week, keep an eye on Wednesday the 9th of September morning. The swell jumps up to 5ft from the S, 10-second period, and it’s glassy from the east at 3 mph. That combined energy is solidly moderate (364), and the reef should handle that size well for a strong, punchy wave. It’s a long way out, so take it as promising but not locked in yet.

The real standout of the whole forecast, though, is Thursday the 10th of September morning. That’s the one to circle. We’ve got 7ft of S swell, period at 10 seconds, and glassy conditions with a light SSE breeze at 3 mph. The combined energy is strong (925)—that’s serious power. This is a wave for the advanced crew only; 7ft on a reef is no joke for beginners. But if you’ve got the skill and the nerve, the wind offshore and glassy will mean clean, proper barrels and long walls. It’s a once-in-the-forecast opportunity.

After that, Friday the 11th drops to 5ft with cross-shore winds, and then it fizzles out into small, weak surf through the rest of the period. There’s a gap from the 11th on where nothing is recommended, so the second week is a bit of a bust. All in all, the first few days and that Thursday the 10th are your best shots.

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.
