The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s comin’ for our stretch of reef. We’ve got one main spot on the table, so this forecast is built around it.
First off, the water is sittin’ at 58°, which is a bit colder than normal for this time of year – that anomaly of -2° is noticeable, so don’t be shy with the rubber.
The outlook kicks off with a solid pulse, but the conditions are a mixed bag to start. Thursday the 10th serves up a punchy 8ft swell from the SW, but those 9-16 mph south winds are blowing cross-offshore. The wave energy is massive – 2457 – but it’s described as marginal, not quite coming together right.
Friday the 11th is where we start to see the clean-up. Morning brings 6ft WSW swell with a proper 12 mph offshore from the SE. The period hits 12 seconds, giving the waves some real shape. Wave energy is still high at 1271. This is excellent for experienced surfers – you’ll get some nice, hollow lines off that reef. The afternoon gets bigger but messier with a short-period 7 second punch from the SSE at 8ft – that’s more of a closeout zone for experts only.
Saturday the 12th is worth waking up for. We’ve got 7ft of SW groundswell in the morning with a very long 15-second period, and then it jumps to 8ft with 16 seconds in the afternoon. That’s serious energy pumping – 2129 in the morning and a whopping 3763 by the arvo. The offshore SE winds hold steady. This is a day for the experienced crew, because that wave height is pushing past the beginner-friendly mark. The long period will make the sets stack up, but on a reef like this, those waves are going to unload with serious power.
Sunday the 13th is an absolute gem. Morning has light east winds and 6ft SW swell (2328 energy). But the standout is Sunday afternoon: 5ft SW swell with 14-second period, and glassy conditions from a 3 mph SSE breeze. The energy is still solid at 1502. That’s as clean as it gets. The reef will be smooth, the waves will be peeling, and you might have company because crowds are sometimes an issue here.
Then we hit a dry patch. Monday the 14th through most of the week goes to junk. Strong onshore winds and messy seas. Nothing worth paddling out for. A few days of flat-to-rubbish conditions.
Wednesday the 16th brings back a big, raw swell – 12ft from the SW with 4651 energy – but it’s a cross-offshore wind. That’s a big, powerful wave. This is strictly for experts. Over 8ft is heavy territory, and with that kind of energy, the reef will be churning.
Thursday the 17th looks more manageable: 7ft SW groundswell with a 12-second period, clean offshore winds out of the SE in the morning. Another excellent session for experienced surfers.
The following weekend, Saturday the 21st, is a serious standout in the long-range. Morning shows 12ft SW swell with 16-second period and a combined energy of 6277. That’s strong, very strong. Winds are cross-offshore from the SSE at 16 mph. The afternoon is basically the same. This is a big, powerful, clean groundswell on a reef. It’s a week and a half out, so it’s promising but not locked in yet.
After that, the swell starts to fade into the end of the 16-day window, with smaller waves and less favorable winds.
The best on offer: Sunday the 13th afternoon for those glassy, clean 5ft waves. And for the bigger, more experienced crew, keep an eye on Saturday the 21st – that 12ft groundswell is the biggest, cleanest pulse of the whole period.
Stay wet.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Off The Wall 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.
