The Lowdown
G’day, Rusty here. Let’s talk about Windang Island for the next couple of weeks. It’s a reef and point setup, a fairly consistent spot that swings up best with swell from the southeast. The water’s sitting at 66.2°, which is a touch warmer than normal for this time of year – not a huge deal, but a nice little bonus.
We’ve got a quiet start today, Saturday the 25th of July, but it’s a beauty. Glassy conditions with a light 3.1 mph westerly, and a clean 3.6 ft south swell rolling in at 11 seconds. The combined energy is moderate at 284. It’s only a small wave, but for a Saturday afternoon with no wind, you’ll be getting some fun, clean lines. Not a standout, but a solid little session.
Sunday the 26th starts off the pick. The morning shows a 5.2 ft south swell, 11 seconds, with a cross-off southwest breeze at 3.1 mph. Clean, meaty waves with moderate energy lifting to 576. This is the best on offer early on – good size, good shape, and the wind is working for you. The afternoon fades into a cross-on, so get in early.
Monday the 27th and Tuesday the 28th are a write-off. Small, weak, or messy. Swell drops to under 3.3 ft, and the wind turns poor. A couple of glassy moments on Tuesday afternoon but the swell is only 1 ft – not worth paddling out for.
Wednesday the 29th is flat and blown out, but the wind is offshore. Tiny 0.3 ft swell – forget it.
Now here’s where it gets interesting. Thursday the 30th of July, a big pulse hits. 11.5 ft of south swell, 10-11 seconds, with combined energy going ballistic at 3773 to 4943. That’s strong wave energy. The morning is clean with a cross-off wind, but the afternoon gets choppy. This is expert territory – over 8.2 ft, so beginners stay on the sand. The size is there, but the quality is marginal due to the cross-shore chop. It’s a big, powerful ocean.
Friday the 31st of July drops slightly to 8.2 ft south-southeast swell, still 10 seconds, still clean in the morning with a cross-off. Energy is still very strong at 2491. Another one for experienced surfers only. The wind stays clean enough for a good session.
Saturday the 1st of August could be the real standout. Morning shows 7.5 ft from the south-southeast, 9 seconds, with a light cross-off breeze. Combined energy is 1418 – strong. The forecast says excellent for experienced surfers. Clean, solid, and the wind is light. This is the session to mark. The afternoon turns cross-on, so it’s a morning-only call.
Sunday the 2nd of August is also a top pick. 6.2 ft southeast swell, long 12-second period, glassy with a northwesterly of 3.1 mph. Energy at 1028 – moderate to strong. That long period means the waves will have some real push and shape, perfect for a point break like this. Glassy, clean, and a touch smaller than Saturday – more accessible for strong intermediates. The best of the two standouts, in my opinion.
Monday the 3rd and Tuesday the 4th of August are smaller again, 4.3 ft dropping to 2.3 ft. Clean enough, but nothing special.
Wednesday the 5th of August brings another big pulse. 9.8 ft southeast swell, 8 seconds, with a clean cross-off wind. Energy is 1239 – strong. Excellent for experienced surfers. The short period means it’ll be a bit lumpy, but the size is there.
Thursday the 6th of August is similar – 11.5 ft from the east-southeast, 9 seconds, energy at 1860. Clean again. Big, raw, expert-only.
Friday the 7th of August, glassy morning with 7.2 ft east-southeast swell, 8 seconds, energy 716. That’s clean and rideable for strong surfers, but the short period will keep it a bit crumbly.
After that, from Saturday the 8th into Sunday the 9th, the swell fades and the wind turns onshore, with rain. Drops to 4.9 ft, and conditions get poor. Not worth chasing.
So, overall: the real standouts are Sunday the 2nd of August for the glassy, long-period quality, and Saturday the 1st of August for the clean, solid size. Get in the water early both days.

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.
