The Lowdown
G’day, Rusty here, and we’ve got a proper mixed bag on our hands for Windang Island. This is a reef-and-point setup, and over the next couple of weeks, it’s gonna take a bit of patience to find the windows. The first few days are a write-off, but there’s some real promise tucked away later on.
We start off Monday, August 10, and honestly, it’s ugly. Swell’s around 6 ft from the ENE, but that cross-off wind out of the NNW at 19 mph is just ruining it. Poor surf conditions, and the wave energy’s moderate (497). Don’t even think about it. Tuesday the 11th morning is still small and ordinary, but look – Tuesday afternoon is where things perk up. The wind swings offshore from the W at 12 mph, and we get a solid 5 ft S swell with a period of 11 seconds. That’s groundswell territory, and the energy’s strong (658). This is a standout for the near term: clean, offshore, and the reef will love that direction. It’s an advanced wave, so leave the foamies at home.
Wednesday the 12th drops right back off with tiny 3 ft S swell and ordinary conditions, but Thursday the 13th morning brings another solid pulse: 6 ft from the S, period 9 seconds, cross-off wind, and strong energy (504). Another very good window. But Thursday afternoon gets a bit sketchy with a cross-on breeze and the swell bumping up to 7 ft, so that’s more of an expert-only affair and the quality drops.
Friday the 14th is a gem for the early crew. Glassy conditions in the morning with a clean 4 ft S swell, period 9 seconds. That’s a beautiful, clean morning session with light winds. Energy’s moderate (239), but the glass makes it a joy.
Then we hit a dry patch. Saturday the 15th and Sunday the 16th are mostly poor or marginal with small, short-period slop and cross-breezes. The swell drops to under 3 ft with periods of 6 seconds – weak energy (86-69). Not worth paddling out.
There’s a bit of a gap through the middle of the week – Monday 17th and Tuesday 18th are all poor with onshore winds and messy chop. A bit of a lull.
But keep an eye on Wednesday the 19th. Glassy again in the morning, 4 ft SE swell, period 8 seconds, and strong energy (326). That’s a clean one. And Thursday the 20th morning? Dead calm, glassy, with a 3 ft ENE swell – that’s about as clean as it gets, though the swell’s a little small. Still, a beautiful paddle-out.
Now, the real highlight of the whole outlook lands on Monday the 24th and Tuesday the 25th. Monday the 24th brings a solid 6 ft SE swell, period 8 seconds, with light cross-off winds in the morning and offshore from the W in the afternoon. Energy’s very strong (706-739). That’s a full day of very good surf. Then Tuesday the 25th morning delivers a 4 ft E swell, but with a long period of 13 seconds – that’s proper groundswell, and the energy’s strong (647). Light cross-off wind and clean. This is the pick of the entire 16 days for Windang Island. The long period might make it a bit straight at the beach, but on this reef-and-point, it’ll set up nicely. Just know the water temp is about average for this time of year at 64°.
Crowds can show up here sometimes, and for a standout like the 24th and 25th, expect some company. That’s the one to circle on the calendar, but it’s a bit over a week away, so keep an eye on the forecasts. For the advanced crew only when it’s over 5 ft, and on the big 7 ft Thursday, that’s expert territory.
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.
