The Lowdown
Righto, let’s have a look at what’s on the cards for the next couple of weeks. The only spot that’s really showing any promise is Windang Island, a reef and point set-up that’s exposed to the south-east swell. It’s a fairly consistent wave, but it’s an advanced wave, so this isn’t one for the beginners.
The water temp is sitting about average for this time of year, so nothing wild there.
The action kicks off proper on Friday the 24th of July. The morning is looking clean with a light offshore breeze out of the WSW and a solid 4ft south swell. The combined energy is moderate, sitting at 300. Then the afternoon turns glassy with an ENE breeze that’s barely a breath, and the swell drops to 3ft but the period stretches out to 12 seconds, giving it a bit more grunt. The combined energy actually jumps up to 387. That’s a sweet little window.
Saturday the 25th keeps the good times rolling. The morning is clean again with a light WNW offshore and a 4ft south swell, and the combined energy is a solid 390. The afternoon goes glassy, with a NNE breeze, 4ft south swell, and a combined energy of 268. Still very much worth a paddle.
Sunday the 26th is the pick of the first week. The morning has a WSW offshore breeze at 10 km/h, pumping out a 5ft south swell with a tidy 10-second period, and the combined energy is a strong 428. That’s the standout for this first run. The afternoon turns onshore, so the morning is your window.
Monday the 27th has a glassy morning with a 3ft south swell, but the energy drops to 150. It’s surfable, but nothing special. After that, things get ordinary. From Tuesday the 28th right through to the end of the month, the swell drops right off, with tiny waves and poor conditions. There’s a stretch of about four days with nothing worth chasing.
Early August sees a bit of a pulse. On Monday the 3rd of August, the morning has a 4ft swell from the east-northeast, but the period is a short 7 seconds, and the combined energy is only 130. It’s clean, but it’s a bit meh. Tuesday the 4th brings a bigger 7ft swell from the south, but it’s short period at 7 seconds, and the wind is messy. The combined energy is 466, but the quality isn’t there.
Now, the real standout is Thursday the 6th of August. The morning is glassy, with a 10ft swell from the southeast, a period of 8 seconds, and the combined energy is a massive 1095. That’s a big, powerful swell. This is for experts only – the size alone will be intimidating. The wind is glassy, so it’ll be clean, but that’s a lot of water moving around. The afternoon stays big but gets a cross-onshore wind, so it’ll be a bit choppy. Still, the morning is the one to circle on the calendar.
Friday the 7th and Saturday the 8th of August continue the big swell trend, but the winds are messier, and the energy is fluctuating. Saturday the 8th has a 12ft swell from the east-northeast with a long 11-second period and a combined energy of 2974 – that’s a serious amount of power. But it’s a cross-shore wind, so the quality will be all over the place. That’s one for the very experienced, and even then, it’s a bit of a gamble.
So, if you’re picking the best of the lot, it’s Sunday the 26th of July for the first week and Thursday the 6th of August for the second week. The first one is a clean, punchy south swell with offshore winds. The second is a massive, glassy, powerful swell, but it’s not for the faint-hearted.

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.
