The Lowdown

Alright, let’s get down to brass tacks for Windang Island.

It’s a slow cooker to start. From Monday the 17th through Sunday the 23rd, the waves are tiny, weak, and mostly a waste of time. You’re looking at swell between 0.2ft and 1.0ft, with short periods around 6 to 10 seconds, so no push at all. Combined wave energy is weak, barely topping 100 (163 at best). Wind is all over the shop – cross-onshore, onshore, choppy – so the surface is usually a mess. A couple of glassy windows pop up on the 18th morning and 21st, but it’s flat and bumpy anyway. That’s a solid eight-day gap of nothing worth paddling for.

Things kick off late on Saturday the 29th, but only for the skilled. Saturday morning brings a S swell at 7ft with a 9-second period, and combined energy shoots up to a strong 1007. Wind is cross-off from the SSW, so it’s clean on the takeoff. That’s expert-only territory – 7ft on a reef and point setup means serious ledges. Crowds are “sometimes” an issue here, so expect a lineup.

The real standout starts Sunday the 30th. You’ve got a building S swell: 7ft in the morning, hitting 8ft by afternoon, periods around 9 seconds, and energy at 771 and 1030. Winds are cross-off morning and cross in the arvo, but it stays clean enough. The 8ft afternoon is for experts only – big, heavy, and powerful on the reef. For the brave, Sunday morning is the pick: big swell, decent wind, and the S direction matches the sweet spot.

Monday the 31st keeps the size at 8ft in the morning with a shorter 8-second period, energy massive at 1469, and cross-off wind. Then Tuesday the 1st of September, the swell drops to 5ft but the period stretches to a sweet 12-second groundswell. Combined energy stays at 734, and it’s glassy in the morning (S wind, 5 mph). This is the more accessible option for good surfers: still decent size, cleaner, with that long period giving the waves shape and punch. On the point, it should wrap in nicely.

Water temp back on Monday 17th is 64°F, about average for the season.

Best on the table: Sunday 30th morning for the big, expert-level grunt, or Tuesday 1st morning for the cleaner, easier-to-handle groundswell. Expect a crowd on the good ones.

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.
