The Lowdown
G’day, Rusty here. Let’s break down what’s cookin’ at Windang Island for the next couple weeks. First few days are a bit of a snooze, but there’s a couple sessions that’ll have you waxing up for sure.
Right out the gate, Wednesday August 5th afternoon has a tiny 1ft easterly windswell with weak energy (25) and a moderate offshore—just poor. Thursday the 6th morning brings a small 3ft southerly swell (8 seconds) but the wind is glassy, so the surface is clean. Still, it’s ordinary. That low-energy story runs through to Saturday the 9th: waves between 1ft and 3ft with either glass or clean conditions, but nothing worth rushing for. There’s a gap of small, unremarkable days.
Then it picks up. Monday the 10th sees swell jump to 7ft from the ENE with strong offshore winds (25 mph) in the morning and 672 combined energy—heavy but tough to paddle into. The afternoon drops to 5ft with fresh offshore wind and 354 energy. This one’s for the strong paddlers only.
Here’s the real standout: Tuesday the 11th. Morning brings a 2ft southerly groundswell with a very long 13-second period, clean offshore wind from the west at 12 mph, and 346 energy. The afternoon is 3ft from the south (9 seconds) with the same clean offshore and 218 energy. Both are flagged as “expect good surf conditions.” This is the pick of the first week. Windang Island is a reef and point, so that long period groundswell will wrap in nicely and produce some lined-up waves. Slight crowds are possible here. Water temp is about 65°F, which is roughly 2°F warmer than usual—pretty nice for August.
Wednesday the 12th through Saturday the 15th drops back into small, poor surf with onshore or cross-shore winds. Not worth your time.
Sunday the 16th is still poor, but Monday the 17th morning delivers another standout: glassy conditions with a 8ft southerly swell, 8-second period, and 727 energy—flagged as “expect very good surf conditions.” The afternoon jumps to 10ft from the SSE with a gentle cross-onshore—still doable but getting big and a bit messy. That 8ft morning glass is the call, but at that size it’s expert territory.
Tuesday the 18th and Wednesday the 19th are pumping with 10ft to 8ft from the SSE/SE, periods up to 12 seconds and massive energy (4274 and 1999). But winds are cross or cross-onshore, and conditions are marginal or poor. This is charging-only, big-wave territory.
Finally, Thursday the 20th cleans up nicely: 6ft from the SE in the morning with a moderate cross-offshore and 964 energy—flagged as “expect very good surf conditions.” The afternoon is 5ft with a gentle cross-offshore and 905 energy, also very good. A solid way to wrap up the outlook.
So, the two absolute best windows: Tuesday the 11th for clean, long-period groundswell on the point, and Monday the 17th morning for glassy 8ft sets. Those are your money sessions. Everything else is either flat, poor, or for the big-wave crew.
Stay safe out there.

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.
