The Lowdown
Let’s talk about the only break that matters: Windang Island, a reef and point that’s fairly consistent. That’s it for the next 16 days, so you’re all in on one spot.
Monday morning July 27th: small surf, 3ft from the south with a 9-second period, glassy conditions, water temperature is a touch warmer than average at 66°. Wave energy is weak at 172. It’s clean but tiny. Monday afternoon gets onshore and dies.
Tuesday through Wednesday is flat. Knee high or less.
Now, Thursday July 30th morning – this is a real alarm clock. A clean 7ft south swell, glassy, with a light southwest breeze. Wave energy jumps to 985 – solid. The direction is south, and the optimum here is southeast, so it’s not a perfect match, but with glassy conditions and overhead sets, you’ll take it. Get out early; the afternoon gets cross-on and messy.
Friday July 31st brings 5ft to 7ft from the south, but the wind is side or side-onshore. The energy is strong – up to 1254 Friday afternoon – but the shape is compromised.
Saturday August 1st has a clean glassy morning with 4ft waves from the SSE. Smaller and cleaner, good for a quieter session.
It drops off again until Wednesday August 5th, when a 6ft to 7ft SSE swell comes through, but with short 8-second periods, it’s bumpy and less refined. Wind is clean enough, though.
Now for the one to book off work: Saturday August 8th morning. This is a massive 12ft southeast groundswell with an 11-second period, dead glassy, and wave energy reading a whopping 5077 – that’s very strong power. The swell direction is exactly what this reef and point wants. But that’s expert territory – over 8ft is for experienced surfers only. This is big, clean, and heavy. Crowds are possible, and they’ll all be there. If you’re good enough, it’s the session of the outlook.
Sunday August 9th still has a nice 7ft ESE swell with glassy conditions in the morning, but the afternoon blows out.
The second week fades into smaller surf, poor winds, and a strong 40 km/h offshore on Tuesday August 11th that makes even 5ft surf a paddle-out mission.
So the two standout moments: Thursday July 30th morning for clean overhead waves, and Saturday August 8th morning for big, perfect, expert-only groundswell. Don’t miss the glass.

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.
