The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window ahead, but it’s a slow-starting, patchy affair at Windang Island. The real action is tucked away in the second week, with a couple of sessions that look absolute gold.

The first real surfable session kicks off on Wednesday the 12th. It’s small, with a 3ft south swell and a 9-second period. The combined wave energy is weak (145). But the wind is a clean offshore from the west, 12 mph, so the surface will be tidy. The water is a pleasant 64°, which is bang on average for this time of year. It’s steers-able, but nothing to write home about.

Thursday morning the 13th sees a slight bump to 4ft from the south, period drops to 8 seconds, and the combined energy lifts to a moderate 194. We’ve got a light WSW cross-offshore breeze at 6 mph, so it’ll be clean. It’s still just ordinary surf, but a step up.

Friday morning the 14th delivers a real treat. The swell drops to 3ft from the south, 8-second period, with moderate energy (182). The wind is dead calm – glassy as a mirror. This is the kind of clean, user-friendly morning where the reef and point will be offering up some fun little lines. Not a standout, but a very pleasant session.

The weekend gets lumpy. Saturday the 15th brings a 6ft south swell, 8-second period, and strong combined energy (392). The wind is a moderate 12 mph cross-offshore from the SSW. This is still clean, but the size is pushy. For experienced surfers, it’s got some grunt, but beginners will find it too big. Sunday the 16th is messy with onshore wind and a short, choppy 5ft SSE swell. Forget it.

Things go quiet and poor from Monday the 17th right through to Saturday the 23rd. The swell is small, the wind is often onshore or cross-shore, and the conditions are just ordinary. It’s a proper flat spell.

Now, here’s the standout. Monday the 24th of August. This is the one. A 6ft south swell rolls in with a solid 10-second period, pumping out strong combined energy of 670. The wind is a fresh 16 mph cross-offshore from the SSW. This is a proper groundswell, and at Windang Island, that long period will produce some excellent, powerful lines off the reef and point. It’s a bit too big for beginners, but for the experienced crew, this is the best session on offer. The water is still clean and the energy is proper.

Tuesday the 25th is a letdown after that, with the swell dropping fast. Wednesday and Thursday the 26th and 27th are mostly small or messy, with a big, lumpy 7ft pulse on the 27th afternoon getting absolutely wrecked by a strong onshore wind. That final one is only for the experts with a death wish.

So, if you’re looking for a moment, lock in the morning of Friday the 14th for small, clean fun, or go hard on Monday the 24th for the real deal. The waiting game is worth it.

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.
