Hey everyone, Rusty here. Let’s break down Windang Island in feet and knots for those who think that way.
Right now, Tuesday the 7th afternoon, it’s a bit of a mess – solid 11‑12 ft SE swell with a 11‑second period, cross‑shore wind from the S at 12 mph. Combined energy is heavy at 4881, and the water’s 66°F, a touch warmer than average. Not glassy, but plenty of power if you’re keen.
Wednesday the 8th and Thursday the 9th – swell drops. Wednesday morning: 8 ft SE, 10 secs, clean cross‑off breeze (SW 9 mph), combined energy 1405. Thursday morning: 5 ft SE, 10 secs, same clean wind (SSW 9 mph). Rideable but nothing special.
Then we hit a lull. From Friday the 10th through Monday the 13th, the swell goes tiny – under 3 ft most days. Friday morning is glassy with 5 ft SE, 9 secs – combined energy 325 – but the size just isn’t there. Sunday and Monday see strong offshore winds (W 15–18 mph) but waves barely a couple feet, energy down to 66. That’s kite‑board weather.
Tuesday the 14th and Wednesday the 15th bring a small S swell – 2–4 ft, 10–11 secs. Wednesday morning is glassy (SW 3 mph) with 4 ft S, combined energy 382. Clean but small.
Thursday the 16th: a new SSE swell – 7 ft at 12 secs by morning, combined energy 1645. Light S wind, so light cross‑shore ripples. Marginal.
Now for the good stuff. Friday the 17th morning – glassy, wind NW at 3 mph, clean 5 ft SSE groundswell with 11‑second period. Combined energy 561. That reef will be smooth and lined up – a great call for experienced surfers.
Saturday the 18th morning – offshore W wind at 6 mph, 5 ft SSE, 10 secs. Combined energy 619. Clean again, a touch smaller but still fun.
But the standout is Wednesday the 22nd morning – two weeks out, so keep an eye on it. Swell jumps to 8 ft SE, 9 secs, combined energy 1057. Offshore W wind at 12 mph – clean faces with punch. The guidance says “excellent for experienced surfers” – this is too big for beginners (over 8 ft). Crowds can pop up here, so be ready.
That afternoon the swell hits 10 ft SSE, 9 secs – combined energy 2233 – but the wind picks up to 18 mph offshore (W). Still clean but getting hefty. Experts only.
So: a slow start, a small mid‑month bump, then a proper pulse at the end. The 17th and 18th are your near‑term windows; the 22nd is a promising long‑range shot but still a week and a half out. Stay patient.
Rusty out.

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.
