The Lowdown

Hey, Rusty here. Let’s talk Windang Island.

First few days? Hardly worth paddling out. Thursday morning September 3rd – a tiny 2ft south swell with a 10-second period, wave energy sitting at 72 – barely a whisper. Wind’s offshore though, so a couple of clean little waves might roll through, but it’s a light day.

Friday morning the 4th is the bright spot early on: 3ft from the south, glassy flat wind, and energy climbs to 182 (moderate). The reef and point will be looking clean and pretty. Perfect for a dawny.

Then things go sideways. Saturday the 5th and most of Sunday the 6th – cross winds, chop, small junky waves. Sunday morning the 6th has a clean 3ft south swell with 180 energy, but it’s just okay.

Monday the 7th – clean again, 3ft, moderate energy, but nothing to write home about.

Tuesday morning the 8th – big jump to 8ft from the south, 9-second period, combined energy of 1726 – that’s very strong. Way too big for beginners, only experts should even think about it. Winds are cross-off and clean, so it’ll look good, but it’s a heavy session. That afternoon drops to 5ft but gets cross-on and choppy.

Wednesday the 9th – rain, cross winds, lumpy 4ft to 5ft. Forget it.

Now Thursday the 10th morning is the real standout: 4ft south swell, 11-second groundswell, combined energy of 436, and clean cross-off wind. That long period will bend beautifully into the point and reef. Crowds are possible here sometimes, but it’s worth it for how clean it’ll be.

Friday the 11th and Saturday the 12th – 3ft to 4ft, long period but cross-on winds and iffy tides. Just average.

Sunday the 13th and Monday the 14th morning – tiny, 2ft to 2ft. But Monday the 14th afternoon brings a nice surprise: 5ft from the SSE, 9-second period, clean offshore from the WNW, energy of 385. That late session could be fun.

Tuesday the 15th through Wednesday the 16th – mostly poor, cross winds, small, short period junk. The 16th afternoon has 4ft from the NE but only 5 seconds – terrible shape.

Thursday the 17th – clean but tiny, 4ft from the NE, 8 seconds, weak energy. Just okay.

Friday the 18th morning – another big one: 8ft from the south, 9-second period, combined energy of 1868. Strong, but cross wind from the north at 15 mph makes it lumpy. That afternoon it’s 7ft and even windier. Experts only, and even then it’s a grind.

Water temp is 64°F – dead average for early September, anomaly of 0.7°F above normal. Nothing special.

Best session: Thursday morning the 10th – 4ft south swell, 11-second groundswell, clean offshore. That’s the one.

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.
