The Lowdown
Right, mate, Rusty here. Let’s have a look at what’s coming our way.
Alright, we’ve got a bit of a mixed bag on the table here. The surf is going to be on and off over the next couple of weeks, with a few real standout sessions that’ll get the blood pumping. The first week is a bit of a slow burner, but the second week, especially the first few days of August, looks like it could be something special.
We’ll kick things off at Windang Island (reef and point). The water temp is sitting at 66°F, which is a touch warmer than normal for this time of year, so that’s a nice little bonus. The first real chance to get the board wet is Sunday afternoon, the 19th of July. There’s a 6ft swell from the ENE with an 11-second period, and the combined swell energy is moderate at 768. The wind is a light cross-on, nothing too nasty, but it’s not perfect. It’s a bit of a marginal session, but you can get out there.
Monday morning, the 20th, actually looks cleaner. The swell drops a touch to 5ft from the same direction, but the wind swings to a light cross-off from the NNW, which should clean it right up. The energy is still moderate (723). It’s a better call for a morning paddle.
The pattern then gets messy through the middle of the week with onshore winds picking up each afternoon, but keep an eye on Wednesday morning, the 22nd. The wind is offshore from the W at 6 mph, the swell is 3ft from the ENE at 10 seconds, and the energy is a modest 204. It’s not big, but it’ll be clean and tidy.
Now, the first real standout comes on Thursday afternoon, the 23rd of July. The wind is a solid offshore from the W at 16 mph, which will groom the wave faces perfectly. A new 7ft S swell rolls in with a 9-second period, and the combined energy jumps to a strong 1029. This is excellent surf for experienced surfers – the size and the offshore wind mean it’ll be powerful and hollow. The crowd profile here is “sometimes”, so you might have a few mates out, but it’s worth the paddle.
The wind stays offshore for the next few days, but the swell drops back. Saturday afternoon, the 25th, has a 4ft S swell but the wind is a fresh 19 mph offshore, which makes it a bit tricky.
The real big show is waiting for Saturday, the 1st of August. The morning session is a proper beast. The wind is a light cross-off from the SSW, the swell is a solid 10ft from the S with a 10-second period, and the combined energy is a massive 3457. That’s strong to very strong wave energy. This is only for experienced surfers, lads – it’s big, powerful, and will be a handful. The afternoon swell pushes to 12ft, but the wind goes cross-on, so the morning is the window.
Sunday morning, the 2nd of August, is also a corker. The wind is glassy from the NW, the swell is still a solid 10ft from the SSE at 8 seconds (short period, so it’ll be punchy), and the energy is still very strong at 1246. This is another one for the experienced crew, and with glassy conditions, it’ll be as clean as a whistle.
After that, the swell starts to back off into the first week of August, with the wind turning onshore or strong, so the quality drops.
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.
