The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this forecast for Windang Island is a bit of a slow burn. We’ve got a long stretch of small, ordinary surf ahead before anything really gets going. The water temp is sitting right on average for this time of year at 64°F, so no surprises there.
The first few days are pretty mundane. Tuesday morning (1st September) sees a weak 3ft south swell with a so-so 11-second period, but it’s cross-shore and the energy is low (175). Not worth paddling out for. Wednesday and Thursday are tiny – 2ft and 2ft – and while the wind goes offshore, the swell is just too small to get excited about. Friday morning (4th) is clean with a light cross-off breeze, but that 3ft south swell (energy 128) is still pretty ordinary. Saturday morning (5th) bumps up a touch to 4ft from the NNE, but it’s a short, choppy 6-second period, so it’s not going to be any kind of classic.
We hit a real quiet patch from the 6th to the 8th, with onshore and cross-on winds and poor surf conditions. The energy dips into the low double digits at times. It’s not looking good at all.
Now, here’s where it gets interesting. The real standout arrives on Wednesday, 9th September. Overnight, the swell jumps to a solid 7ft from the south, with a nice 10-second period. The wave energy rockets up to 817 (moderate). It’s a bit of a cross-shore wind in the morning, but the light breeze keeps it from being a total mess. This is a proper reef and point setup, so that south swell will wrap in nicely. The afternoon sees it push to 7ft (energy 1769 – strong), but it turns cross-on. Still, for an advanced surfer, this is the best window we’ve got. The 8ft swell on Thursday morning (10th) is a beast, but it’s big – over 8ft – so that’s expert-only territory. The wind is light cross-on, and the energy is 1517. This is big, powerful, and not for the faint-hearted.
After that punch, the swell backs off quickly. Friday (11th) is dropping out, with poor winds, and the rest of the 16-day run fades into tiny, clean but weak surf. The energy values drop to 57 and below. For the last few days, it’s just small groundswell with offshore winds, but nothing worth rushing for.
The one true standout is the 9th and 10th of September. That’s the call. If you’re an advanced surfer, get ready for that Wednesday. It’s the best on offer by a long shot. Crowds are likely at Windang Island, so get in early. For the rest of the run? It’s a waiting game.
Rusty.

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.
