The Lowdown

G’day, Rusty here. Let’s be straight up: this forecast for Windang Island is a real mixed bag, and mostly a quiet one. We’ve got a bit of a wait on our hands before anything worth paddling out for shows up. The first week is pretty flat and ordinary, but there’s a little pulse of energy building towards the second weekend that might just be the standout of the whole 16-day run.

Right now, Wednesday morning the 5th of August, there’s almost nothing doing. A tiny 1.0ft easterly wind swell with a short 10-second period, and only 36 weak energy units (36) – that’s barely a ripple. Water temp is sitting at 65°, which is about a degree warmer than usual for this time of year, so it’s a bit on the mild side but nothing crazy. You’d be wasting your time.

Thursday the 6th sees a small bump. Morning brings 3ft from the south with an 8-second period and moderate energy (112). The wind is glassy, WSW at 5 km/h, so it’ll be clean, but the waves are pretty average. The afternoon goes cross-onshore and choppy – not worth it.

Friday the 7th and Saturday the 8th are more of the same: tiny swell, glassy mornings but ordinary conditions. Sunday the 9th gets a bit of energy (134) from the ENE, but the wind is cross-shore and messy. Still not a goer.

Now, Monday the 10th is where things get interesting. A pulse of 6ft from the ENE with 9-second period hits in the morning, backed by a strong 462 energy units (462). That’s moderate-to-strong energy. Wind is WNW at 30 km/h, cross-offshore, so it’ll be clean. This is the standout of the first week – it’s the biggest swell of the run so far, and it’s over 5ft, so it’s getting into that intermediate-to-advanced zone. The afternoon drops to 4ft but stays offshore with fresh 30 km/h W winds. It’s clean, but the morning is the pick.

Tuesday the 11th drops back to 2ft but with a long 12-second period from the south (162 energy) – that’s a proper groundswell, which will be better shaped but might break a bit straight at this beach-and-reef setup. Offshore winds again, so clean but small.

The second week is pretty lean. Wednesday the 12th through to Wednesday the 19th of August is a long stretch of tiny swell, mostly under 3ft, with weak energy. There’s a brief moment on Friday the 14th morning with 3ft from the south, glassy winds, and 192 energy – surfable but ordinary. Then it fades again.

The real standout of the whole outlook? That’s Monday the 10th of August morning. The biggest swell (6ft), the strongest energy (462), and clean cross-offshore wind. It’s a reef and point setup, so it should handle that ENE direction well, and the optimum swell direction for Windang Island is SE, so it’s not a perfect match, but the size and cleanliness make it the best on offer. Crowds can be around sometimes, so don’t expect to have it to yourself, but it’s worth the paddle.

After that, the forecast goes quiet again. From the 15th through to the 20th, it’s mostly under 3ft with weak energy and choppy or onshore winds. Not much to get excited about.

So, bottom line: if you’re keen, get out Monday the 10th morning. The rest of the run is a waiting game.

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.
