Righto, let’s have a look at what’s comin’ our way.
The first decent surf window opens up Saturday morning at Windang Island. It’s a reef and point set-up, exposed to the south swell. Saturday morning we’ve got a clean 3-foot wave from the south with a nice 12-second period, light offshore wind from the WSW at 6 mph, and water sitting at 66°, which is a touch warmer than normal for the time of year. The combined swell energy is weak (235), so it’s small but tidy. This is the only really clean, surfable slot early on—the afternoon goes cross-on and poor, so hit it early.
Sunday through Tuesday the swell jumps significantly—8 foot and bigger—but the wind turns messy. Sunday morning has a cross-off wind but it’s 16 mph, and the combined energy is strong (1653), but the conditions are only marginal. The swell period drops to 10-11 seconds, so it’s still groundswell but not super long. By Tuesday morning we’ve got clean 8-foot cross-off conditions, but the waves are still only rated marginal, with strong energy (1260). This stretch is really only for experienced surfers and even then it’s not pristine.
Wednesday the 8th of July morning looks like the standout of the first week. Windang Island has 10-foot swell from the SSE, a 10-second period, and clean conditions with a light cross-off breeze from the SW at 9 mph. The combined energy is very strong (3277). This is legit groundswell—plenty of power, long lulls, and decent shape for a point/reef. Only for confident paddlers though; it’s well over 8 foot.
After that, Thursday and Friday drop back to the 6-7 foot range with cleaner winds. Friday the 10th is particularly nice with light cross-off breezes and very good surf conditions, though the combined energy is moderate (840-961). Saturday the 11th is smaller again at 5 foot with clean offshore airs, but the energy drops to 420.
Then there’s a real gap. From Sunday the 12th afternoon all the way through to Wednesday the 15th, it’s tiny—most of it under 3 foot, very weak energy, and nothing worth paddling out for. Thursday the 16th morning shows a small pulse of 5 foot from the south with light cross-off wind, clean, but the energy is still modest (340). That’s a possible quick session but nothing special.
The real standout is further out, on the 18th of July Saturday afternoon and the 19th of July Sunday morning. Saturday afternoon brings 12 foot from the south, clean offshore wind from the west at 9 mph, and very strong energy (2200). Sunday morning tops it: 13 foot from the SSE with a 11-second period, clean offshore from the west, and massive combined energy (4121). This is big, powerful groundswell, glassy offshore conditions—absolutely pumping. Only for experts, and the crowd factor is “sometimes,” so you might have a few mates out but it’s not packed. This is the one to circle on the calendar, even if it’s long range.
So, bottom line: Saturday morning this week for a clean small one, Wednesday the 8th for the first big clean swell, and then the real gold is on the 18th and 19th—big, clean, offshore, and all yours if you’ve got the nerve.

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.
