The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this 16-day run for Walton Rocks (Power Plant) is a tough one. We’re lookin’ at a whole lot of nothing. The first surfable day that even raises an eyebrow isn’t until Tuesday, 18 August, but even then it’s not worth paddling out for. From now until the end of the window, every single session is labelled “poor surf conditions” with a score of zero. That’s a blank run of 16 days.
The only flicker of something happens on Tuesday morning, 18 August. We get a clean, light cross-offshore wind from the WNW at 6 mph, with a small 2 ft swell out of the ENE, period 7 seconds. The combined energy is weak at 35, so there’s hardly any push. For a beach and reef setup exposed to the NE, that’s a dribbler at best. It’s not going to break properly – period’s too short and the size is tiny. If you’re desperate, you might find a knee-high ripple, but don’t expect a wave you can actually ride. After that, it’s right back to flat, choppy conditions for the rest of the week and into the next.
The water temp on Tuesday afternoon, 11 August, was 84°, which is 0.5° below the norm for this time of year – nothing unusual there, just your typical warm bath. But honestly, with no swell to speak of, it doesn’t matter. This spot is exposed to the NE and the optimum swell direction is from the NE, so when something does come, it’ll line up, but there’s nothing on the horizon worth getting excited about.
No standouts here, no hidden gems. The whole 16 days is a write-off. Forecasts can change, but right now, leave the boards at home.
Rusty.
