Table - best surf conditions forecast for Windang Island over the next 16 days.
G'day, I'm Rusty. Let's have a look at what's on the cards for Windang Island, a reef and point set-up that's gonna be the sole focus for the next couple of weeks.
Right off the bat, we've got a bit of a wait. The first session worth paddling out for is Thursday morning, the 9th of July. The water's sitting at 65°, which is about 2° warmer than usual for this time of year – a nice little anomaly that's worth noting. The swell is a solid 5ft, heading straight out of the SE, wrapping in with a period of 10 seconds. The combined energy is moderate, sitting at 721. What really makes it a standout is the cross-offshore wind from the SSW, keeping things clean. The water's gonna be a bit lumpy from the last few days, but the surface should be tidy. Crowds are a possibility here, but the conditions are too good to ignore.
The pick of the whole forecast, though, is Saturday morning, the 11th of July. The swell drops a touch to 4ft from the SE, but with a period of 9 seconds and a combined energy of 330, it's still got a bit of push. The wind is dead calm and offshore from the NW, so it's going to be glassy. The sky is clear, and the surf will be clean. If you want a window that's not too big and not too small, that's it.
Best on offer:
- Thursday morning, 9th July: 5ft SE swell, cross-off SSW wind, clean. Crowds possible.
- Saturday morning, 11th July: 4ft SE swell, glassy NW offshore wind, clean.
After the Saturday morning session, the surf drops off a cliff. Sunday the 12th through to Tuesday the 14th are tiny, with strong offshore winds blowing the little swell flat. It's a dead zone for a few days.
Wednesday the 15th sees a spike in size, but it's a messy one. The swell jumps to 5ft in the morning, but the wind is a strong 19 mph cross-off from the SSW, and it's raining. The combined energy is 219, but it's not going to be clean. By the afternoon, the wind cranks to 25 mph from the SSE, the swell hits 10ft, and the energy skyrockets to 1575. That's a lot of power, but the wind is cross-shore and the surface is messy. This is more of a kite-surfing setup than a clean paddle session.
The rest of the second week is a bit of a mixed bag. Thursday the 16th and Friday the 17th are big, with 10ft to 12ft of SSE/SE swell, but the wind is onshore or cross-onshore, making it lumpy and choppy. The combined energy is massive – 1814, 1975, and even 3858 on Friday afternoon – but the conditions are poor. For a break like this, those big numbers mean a lot of water moving around, but not for a nice surf.
The outlook improves slightly on Sunday the 19th of July. The swell drops to 6ft from the ESE, with a 10-second period, and the wind is a light cross-off from the SSW. The combined energy is 656, and the surf is clean. It's a good option for a late-morning paddle, but the earlier sessions are the real standouts.
Monday the 20th and Tuesday the 21st are smaller, with 4ft and 2ft swells respectively, but the wind stays light or cross-off, so there's something to be had. The last few days of the forecast, the 23rd and 24th of July, drop off again, with small, ordinary conditions.
So, in short: the first week has the best windows, especially the Thursday morning and the Saturday morning. The second week has a lot of size but poor wind, so pick your moments carefully. Keep an eye on the window, because the conditions can change.
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.
