The Lowdown
Alright folks, Rusty here. Let’s be real about this stretch. The forecast for our zone isn't pretty. We're looking at a solid run of messy, wind-blown conditions for the most part. We've got a long, frustrating gap with no real surf on offer, so if you're jonesing for a wave, you might wanna find something else to do for a while. But I’ll walk you through it day by day.
This Friday arvo, the 14th, is a write-off. The swell is there at 7ft, but the wind is a strong cross-onshore mess. It’s choppy and ugly. We’re seeing moderate wave energy (540) and it's a no-go.
Saturday the 15th? Forget it. A near gale kicks up, blowing cross-onshore with the swell jumping to 10ft and then 12ft. It’s a blown-out, dangerous mess. Not worth the drive.
Now, Sunday morning, the 16th, is where things get interesting, just for a window. The wind swings around to a light cross-offshore, which cleans things right up. We’ve got solid 12ft east swell at 9 seconds, driving strong wave energy (1856). This is big, well-over 8ft, so it's for experienced surfers only. The problem? It's forecast to be too big for this spot, and there's a risk of thunderstorms. It's a standout in the sense that it's the only time the wind and the size get you excited, but you gotta be on your game. This is the first real highlight of the whole run.
Sunday arvo, the swell drops to 8ft but the energy fades (946) and it’s only rated as marginal. Still clean, but it feels like a letdown.
Then, the drought hits. From Monday the 17th through to the morning of Saturday the 22nd, we’re looking at weak, short-period swells in the 2ft to 6ft range with mostly cross or cross-onshore winds. It’s a whole lot of nothing – bumpy, weak lines with no push. That’s a solid five days of no surf worth paddling out for.
Saturday afternoon the 22nd, the wind eases to a light offshore, and we get a brief glimpse of clean, rideable waves at 4ft. But the period is a short 7 seconds and the energy is weak (140). It’s surfable, but you’ll be doing a lot of work for not much reward. It's a bummer.
Sunday and Monday, the 23rd and 24th, go back to being poor – moderate to fresh cross-shore and cross-onshore winds ruining the small swell. Nothing doing.
The 25th and 26th? Even more of the same. Cross-onshore winds with 5ft to 6ft of short-period slop. Not a chance.
Now, hold on. As we get into the second week, there's a flicker of promise. The 27th of August... a long-period groundswell starts to show up. We’re talking 17-second periods from the east. The swell’s not huge – around 4ft to 4ft – but that long period means real energy. The wave energy is strong (over 1000). The wind is still light but cross-shore, creating some ripples. The spot is exposed, and that long period at a place like this can start to connect. It’s tricky, still just a marginal call on the 27th and 28th, as it's light cross-shore winds and not perfectly clean. But for the first time in a long while, it looks like there's some actual push in the water. Keep an eye on this – it's promising, but far off a sure thing.
Finally, the 29th rolls around. We see the swell size bump up to a strong 7ft from the east-northeast, but the period drops back to a weak 8 seconds. The energy stays moderate (931-1004), but that cross-shore wind messes it up again. It's a classic case of a building swell with the wind just not cooperating.
So, to wrap it up: The standout for the whole two weeks is that early window on the morning of the 16th – big, clean and powerful, but gnarly. The long-period swell late in the month on the 27th and 28th is a hopeful prospect, but it's a gamble. For the rest of it, honestly, you might be better off kiting if you've got a rig – the cross-shore winds and decent swell size for the second half of the period would be more fun than trying to surf this slop.
Stay patient, this run of bad luck can't last forever.
Rusty.
