The Lowdown

G’day, Rusty here. Looks like we’re in for a pretty quiet stretch for a while, but there’s a couple of moments that’ll get the blood pumping if you’re keen to paddle out.

Right off the bat, Tuesday morning (August 11) is a bit of a write-off – just a small 2ft southerly swell with an 11-second period, clean enough with that WSW offshore breeze at 19 mph, but the combined energy is weak (212) and the call is “marginal.” Not worth rushing out for.

Tuesday afternoon, though, things start to look a bit more interesting at Windang Island (reef and point). We’ve got a solid 5ft south swell pushing in with a 10-second period, and that WNW wind at 16 mph is offshore, keeping things clean. The combined energy jumps to moderate (617). This is the standout for the whole outlook – just about the only time the swell size and conditions line up. The water temp is sitting at 64°, which is about average for the time of year (anomaly of 1°). This one is for the advanced crew only, as it’s over 5ft.

Wednesday morning (August 12) still has some life – a clean 3ft south swell with a gentle offshore breeze from the WNW. Combined energy is moderate (221). But by Wednesday afternoon, the quality drops off quickly. From Thursday onwards into the weekend, it’s a pretty grim run. The swell sticks around the 3ft to 5ft mark, but the wind turns cross, cross-on, or even onshore, and the periods drop to 6–8 seconds. Combined energy stays moderate (up to 531) but the ratings show “poor surf conditions” for multiple days. Saturday (August 15) and Sunday (August 16) look particularly rough – strong cross-shore and cross-onshore winds, short-period, choppy mess.

There is then a significant gap of several days with no real recommendation – from Thursday 13th right through to Monday 24th August, the outlook is mostly “poor surf conditions.”

However, if you can wait, Wednesday morning, August 26 offers a surprise. We’ve got a 4ft north-easterly swell with an 8-second period, and it’s glassy – wind from the west at just 3 mph. That’s light, clean, and the combined energy is moderate (200). This is the other real standout, but it’s a ways off, so keep an eye on it. The swell direction (NE) isn’t the optimum (SE) for Windang Island, but with glassy conditions, it’s worth a look for a fun paddle. It’s just over 3ft, so manageable for intermediate surfers, though not a big day.

For the advanced surfers, Tuesday afternoon (August 11) remains the best single session in the window. For everyone else, that glassy Wednesday morning on the 26th is the one to mark on the calendar.

Rusty out.

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.
