The Lowdown
Alright folks, Rusty here. Let’s have a look at what Windang Island has in store for us over the next couple of weeks.
Right off the bat, there’s a bit of a lull. The early part of the week is pretty grim with small, messy waves and poor winds. We’re looking at a few days of weak, choppy conditions for the most part before things start to clean up.
Now, the standout window is shaping up for Thursday morning, the 27th of August. We’ve got a 4ft south swell with a moderate energy reading (284) and the wind is going glassy, dead calm. That’s going to make for some super clean, lined-up waves on that reef and point setup. This is a solid option for the advanced surfers out there, and with that offshore direction being spot-on for the optimum swell direction (SE), it’s the pick of the fortnight.
A bit further out, Monday morning the 31st of August also looks promising. It’s a much smaller swell, only 2ft, but it’s a very long period groundswell coming from the SSE with a period of 19 seconds. The energy reading is up there at 300, and it’ll be glassy again. While the size is tiny, that long period will offer some real smooth, powerful lines, best for the point and reef there.
Into the first week of September, Tuesday the 1st offers a clean 2ft south swell with a 13-second period and light cross-off wind from the NW. The combined energy is 215, so there’s some push in it, but it’s still on the small side. It’s a cleaner, more surfable option than what we’ve had.
For the rest of the window, most days are a washout with onshore winds and small, poor-quality surf. The water temp is sitting around 64°, which is about average for the time of year, so nothing unusual there.
So, to wrap it up: keep your eyes on Thursday the 27th for the best chance of a good session. Monday the 31st is a long-range call for a small, but very clean, glassy wave. Everything else looks pretty average.
Stay stoked.
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. 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.
Windang Island is 7 km (4 miles) from the city of Port Kembla. If you plan a holiday in Illawarra, look for hotels and other accommodation in Port Kembla. Port Kembla has rooms for a wide range of budgets as well as car hire and transport links.
