Table - best surf conditions forecast for Windang Island over the next 16 days.
Alright, let’s get into it. This is Rusty.
First up, we’ve got Windang Island. It’s a reef and point set-up that’s exposed to the SE, and the optimum is SE swell. For the next few days, there’s a bit of a mixed bag, but the real standout is Thursday morning.
Thursday the 9th kicks off with a solid 5 ft SE swell, period around 10 seconds, and a light SSW cross-off breeze. That combo is giving us clean, lined-up waves. The combined energy is 721, which is solid moderate energy, and the call is “very good surf conditions.” This is the best on offer for the whole run.
Friday the 10th holds that same 5 ft SE swell, but the energy drops a touch to 456 in the morning. Still clean, and Friday afternoon goes glassy with a 5 ft SE swell and a period of 10 seconds – that’s a proper session if you can sneak out.
Saturday the 11th sees the swell back off a little to 4 ft in the morning, still cross-off and clean, then drops to 3 ft in the afternoon with a glassy surface and a longer 11-second period. Great for a longboard or a fun mid-length.
Sunday the 12th onwards, the swell plummets. We’re looking at 2 ft or less, with strong offshore winds. The energy readings drop into the double digits – 76, then 42. That’s weak. A couple of small bumps mid-week on Monday and Tuesday, but nothing worth paddling for.
Wednesday the 15th gets interesting for the wrong reasons. The afternoon brings a jump to 8 ft S swell with a short 11-second period, but the wind is a strong cross-off at 28 mph. The energy is massive at 1642, but the conditions are described as marginal and the score is low. This is more of a kite-surfing setup than a paddle session.
Thursday the 16th is even bigger and gnarlier – 10 ft S swell, 9-second period, and 34 mph winds. That’s 2010 combined energy. Only for the crazy crew, and even then, the cross-shore wind is going to make it a mess.
The following week, from Sunday the 19th, the swell settles back. Sunday morning has 4 ft S swell, 8-second period, with a cross-off breeze and clean conditions. Energy is 243. It’s surfable, but nothing to write home about. Monday the 20th has a similar size, 3 ft, but a longer 12-second period and offshore wind – that could be a clean, fun little session.
After that, it trails off into tiny waves and poor conditions for the rest of the forecast period. The 16-day window has a real gap from about the 12th through the 18th where it’s mostly poor or blown out.
All up, your best bet is Thursday the 9th. That’s the one. Don’t miss it.
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.
