The Lowdown

G’day, Rusty here. Look, I’m not gonna sugarcoat it – the next week and a half is a real mixed bag for Windang Island. The good news is there *are* a few windows of clean surf, but you’ll need to be patient and pick your moments. The opening days are pretty flat, but we’ve got a couple of standouts that’ll make it worth hanging in there.

The first real chance of anything decent pops up on Thursday, August 6th. The morning brings a light westerly breeze – clean and offshore – with a 3ft south swell, but it’s pretty short-period at 8 seconds. The combined energy is weak (99), so don’t expect much push. It’s just surfable, nothing to get excited about.

Friday the 7th is a bit better, with glassy conditions in the morning and a 2ft south swell. The energy is still moderate (143), but the glassy surface will make it look nice. Again, it’s ordinary surf, but you could get a few fun ones if you’re not fussy.

Saturday the 8th has another glassy morning, but the swell drops to 2ft with energy fading (98). It’s a bit of a lull.

Now, the first real standout is Monday the 10th of August. The morning shows a clean cross-offshore breeze from the WNW with a 5ft swell from the ENE. The combined energy jumps to a solid 309 (moderate), and the winds are clean. The afternoon gets even better – a fresh offshore from the WNW at 19 mph, with a 4ft ENE swell. It’s still a bit short-period at 9 seconds, but that’s a decent size for the island and the offshore wind will groom it nicely. This is the pick of the first week for sure.

We then get a few days of clean but ordinary surf, with a bit of a pulse on Wednesday the 12th – a fresh offshore from the WSW at 22 mph, with a 4ft SSW swell, but the period is a short 6 seconds. Energy is moderate (216), but the wind is strong, so it’ll be a bit blown out even if it’s offshore.

But the real gem is shaping up for Friday the 14th of August. The morning is glassy, calm, with a 5ft south swell at 11 seconds. That’s groundswell, folks. The combined energy is 557 (strong), and the water temp is 65°F – a touch warmer than normal for this time of year. The glassy conditions will make it absolutely clean. This is the best on offer across the whole outlook. It’s got size, period, and a glassy surface. It’s a point-and-reef set-up, so that long-period south swell will wrap in nicely. This is the one to circle on the calendar.

Saturday the 15th has a glassy morning with a tiny 1ft SSE swell, but the period is a whopping 23 seconds – that’s very long-period groundswell. Energy is still strong (316), but the size is tiny. It’ll be super clean, but you’ll be waiting for the sets.

There are a few more glassy mornings toward the end of the outlook, like Sunday the 16th with a 4ft south swell at 10 seconds and moderate energy (264), but the afternoon winds turn onshore. It’s consistent enough to keep hope alive.

Summary: The standout is Friday, August 14th – Windang Island with a 5ft south swell, 11-second period, and glassy conditions. That’s your best shot. Second best is Monday, August 10th with a 5ft ENE swell and clean offshore winds. The rest of the fortnight is mostly small or ordinary, but those two windows are worth waiting for.

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.
