The Lowdown

Alright folks, Rusty here, and I’ve been staring at the charts for Windang Island. It’s a reef and point setup, exposed to the south swells, and it’s a pretty solid spot for you advanced lads and lasses. Let’s break it down.

We’ve got a bit of a slow start, but the first decent surf we see is on the morning of Wednesday, July 15th. Don’t get too excited just yet, though. The ocean is throwing a 10 ft swell from the S, but it’s got a messy 10-second period, and the wind is a cross-off at 12 mph. The water is sitting at 65°, which is about normal for this time of year, maybe a touch warmer than average. The wave energy is massive, reading 2336, but honestly, the conditions are a bit marginal for a clean paddle. It’s a big, powerful groundswell, but it’s not quite coming together perfectly.

The rest of the week is a bit of a write-off. Thursday and Friday see the swell drop and the wind shifts around, giving us nothing but poor surf. There’s a long gap with no real recommendations until the following week.

Now, if you’re looking for the standout, you’ve got to circle the morning of Sunday, July 26th. That’s the one. The swell is pumping in at 8 ft from the S with a 10-second period, giving us a combined energy of 1999. That’s a big, powerful groundswell. The wind is light from the S at 3 mph, making it a clean cross-shore. This is proper, heavy stuff – over 8 ft, so this is strictly for experts only. The crowd might be around, but for a wave like that, it’s worth the company.

But the absolute best of the lot, the one I’d be circling on the calendar, is the morning of Monday, July 27th. That’s the winner. The swell is still a solid 5 ft from the S, but the period stretches out to a very long 12 seconds. That’s pure groundswell energy, and it’s going to wrap around that point beautifully. The wind is glassy – a full-on glass-off with a SW breeze at 3 mph. The combined energy is 796, so it’s got plenty of grunt, but it’s clean. The water will still be warm-ish. This is your session. The crowd factor is there, but when the wind is dead calm and the point is working, you don’t care who else is in the water.

The week after that, Tuesday the 28th and Wednesday the 29th, still have some waist-to-chest high waves with clean cross-off winds, but the energy is tapering off, and the swell is dropping. By Thursday the 30th, it’s pretty much gone.

So, the call is simple: if you’re an expert, wait for the morning of the 27th. That’s the one. The weekend before is big, but the Monday morning is the cleanest, most powerful, and most satisfying wave of the whole 16-day window.

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.

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.
