The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Windang Island over the next couple of weeks.
Right now, it’s a bit of a slow start. Tuesday morning (21 July) there’s a cross-shore breeze and the swell is only 4 ft from the ENE with a 10-second period, but it’s pretty messy. Combined energy is moderate (392). The water is sitting at 66°, which is a touch warmer than normal for this time of year. Honestly, not worth paddling out for. Tuesday afternoon is even worse – chop and cross-onshore wind.
Wednesday morning (22 July) shows a real improvement. We’ve got a clean 3 ft swell from the ENE with a 10-second period and a light offshore wind from the west. The combined energy drops to moderate (202), but conditions are clean. Wednesday afternoon goes glassy – offshore wind drops to a glassy 3 mph. Tiny waves, but if you’re keen for a smooth session, it’s there.
Thursday (23 July) has a bit more wind but the swell drops to 3 ft, so it’s small and clean offshore but not really doing much. Friday morning (24 July) is where things start to get interesting – a 5 ft south swell with a 9-second period, light offshore wind from the WSW, and combined energy moderate (322). That’s clean and fun. The south swell direction is a good match for the reef and point setup here. Saturday morning (25 July) keeps that south swell going at 5 ft, 10-second period, and a gentle offshore from the west. Combined energy is moderate (441). This is one of the better windows.
Sunday morning (26 July) is a standout – glassy conditions with a light offshore, 4 ft south swell at 10 seconds, combined energy moderate (308). That’s clean, lined up, and should be a joy. The reef and point should handle that south swell nicely.
Monday (27 July) drops off to 3 ft, then Tuesday (28 July) is tiny and poor. Then we hit the big one. Wednesday morning (29 July) – 8 ft from the south, 9-second period, combined energy strong (1931). That’s a big swell. The wind is offshore from the SSW, so it’s clean. This is only for experienced surfers – it’s too big for beginners. The reef and point will handle that south swell well, but at this size, it’s a serious session. This is a standout for the second week.
Thursday morning (30 July) is even bigger – 8 ft south swell, 8-second period, combined energy very strong (1360), and it’s glassy. Zero wind. That’s excellent for experts again. The crowd profile at Windang Island says “sometimes,” so you might have company, but it’s worth it.
Friday morning (31 July) holds at 7 ft from the SSE, 8-second period, combined energy moderate (462), with a clean cross-offshore wind. Still good for experienced surfers. Saturday morning (1 August) drops to 5 ft from the SE, 9-second period, combined energy moderate (523), and glassy conditions. That’s a very good session for those who are comfortable.
After that, the swell fades into smaller, choppier conditions through the first week of August. The last real standout is the big swell on 29–30 July. If you’re an expert, those are the days to circle.
Rusty.

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.
