The Lowdown

Alright, let’s see what we’ve got. This is a regional outlook for Windang Island, a reef and point break that likes swell from the southeast. The forecast window stretches out sixteen days, and the first bit of surf worth paddling out for shows up on the morning of Friday, September 4th.

Right out of the gate, Friday morning the 4th is looking sweet. We’ve got a clean 3ft south swell, period of 9 seconds, with glassy conditions and a light offshore from the WSW. The combined swell energy is moderate at 214. That’s the kind of start that gets you excited. Keep in mind this break can see crowds sometimes, so early might be your move.

The surf then drops off and we hit a flat spell. Saturday the 5th and Sunday the 6th are basically poor, with small weak energy on offer and cross or cross-off winds. Monday morning the 7th serves up another window: 4ft south swell, glassy again, with moderate energy (214). It’s clean and rideable, but nothing huge. The water temp is about average for the time of year here.

Tuesday the 8th brings a jump in size – 8ft south swell in the morning, but with a cross wind and a period of only 8 seconds. The energy is strong at 1338, which is a lot of water moving, but the short period and cross breeze mean it’s messy and marginal. That’s big enough to be a handful for beginners, and the quality is iffy. Wednesday the 9th is ordinary.

Now, the standout in this whole run is shaping up for Thursday the 10th. The morning already has a solid 8ft south swell, period 11 seconds, and energy at 1872 – that’s very strong. But it’s the afternoon that’s the real talker: still 8ft, south direction, period 10 seconds, and the combined energy jumps to 3054. That is strong to very strong wave energy for this spot. The wind is cross, and it’s marginal, but that’s a proper groundswell pulse. That size is expert-only territory. For the experienced crew at Windang Island, that Thursday afternoon could be the most powerful session of the whole forecast.

After that, the energy backs off. Saturday the 12th morning is a glassy 4ft southeast swell with 11-second period – clean lines and moderate energy at 439. That’s a good, fun morning. The following week has a few glimpses: Tuesday the 15th morning shows a clean 4ft south swell with offshore west wind, and Wednesday the 16th morning has a small 3ft south swell with glassy offshore wind and a nice 11-second period. Both are clean and surfable.

From Thursday the 17th onward, it deteriorates fast with strong winds and rain. Friday the 18th has 5-6ft south swell but with strong cross winds at 28 mph – messy and blown out. That’s more kite-surfing energy than paddle surfing. The last day, Saturday the 19th, has a cleaner look with cross-off wind and a 6ft south swell (period 11 seconds, energy 771), but the strong breeze is still there.

Best of the bunch? Thursday the 10th afternoon if you’re an expert and can handle the power. For a cleaner, more user-friendly session, Friday morning the 4th or Saturday the 12th morning are your windows. The second week has a couple of clean but smaller days on the 15th and 16th.

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.
