Alright, Rusty here. Let's break it down.
We're looking at a slow start for Windang Island. The first solid action is a decent pulse Friday morning, July 10th. You’re looking at clean surf around chest to head high (5ft) from the south-east, with a light cross-off breeze. Water temp is sitting around 65°, which is about a degree and a half warmer than normal for this time of year – a nice little touch. The combined wave energy is moderate, coming in at 582. It's a reef and point setup, so it holds that SE swell well. Friday afternoon drops off quickly though, so make the most of the morning.
The standout of the entire run, and the one to circle on your calendar, is the morning of Friday, July 17th. We’ve got a serious double-overhead plus swell (12ft) from the east-south-east, with a long period of 11 seconds. That’s a lot of juice in the water. The combined energy is a massive 5126, so you know it’s pumping. The wind is light, but cross, which might put a little texture on it. This is advanced territory – over 8ft, it's expert only. The swell direction matches what this break loves (SE), so the wave quality should be there for those who can handle it.
For the rest of the first week, after that initial Friday, we’ve got a quiet spell. Saturday the 11th has a glassy morning with a smaller waist-high swell (4ft) from the SE (352 energy), which would be a fun, smaller session. Then Sunday through Tuesday it’s small and clean but tiny – like ankle to knee high. Not worth paddling out.
The action picks up again big time on Wednesday, July 15th. The morning shows a head-high plus swell (7ft) from the south (744 energy), but it gets blown out by a stiff cross-off wind. That afternoon jumps to a 10ft south swell (1122 energy), but again, messy with the wind. The following Thursday morning, July 16th, looks better for a session – a cleaner overhead (8ft) SSE swell (709 energy) with lighter cross-off winds.
After the big Friday the 17th, the weekend keeps the energy going. Saturday morning, July 18th, is another solid one: 8ft ESE swell with glassy cross-off winds and 1269 energy. The morning of Sunday the 19th is similar, 8ft but with a longer 12-second period and 1759 energy. Still, these are not as clean as the Friday.
After that, the second week settles down into a more run-of-the-mill pattern. There’s a nice little run from Tuesday the 21st through Thursday the 23rd with clean offshore winds and waist to chest high swell (4ft to 4ft). The energy is moderate, in the 300-500 range. It’s consistent and clean for a couple of days, but nothing massive. The final standout in the outlook is the morning of Friday, July 24th: a clean chest high (5ft) E swell (873 energy) with light offshore wind. A solid way to end the period.
So, bottom line: If you’re an experienced surfer, the morning of Friday, July 17th is the absolute best bet. For a fun smaller wave with clean conditions, Saturday July 11th morning or the Tuesday through Thursday of the second week are your best bets. Crowds at Windang Island can happen sometimes, so keep that in mind.

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.
