The Lowdown
Hey folks, Rusty here. Gonna be real with you, the next couple of weeks at Walton Rocks (Power Plant) are a bit of a struggle, but there's a glimmer of something better if you can wait it out.
Right now and for the next week or so, it's flat to tiny. We're looking at waves barely hitting 2 ft, with a weak, short-period easterly windswell. It's just not doing anything. The water's warm though, sitting at 85°F, which is about average for this time of year. There are some glassy windows here and there, like Monday morning the 14th, but with only 1 ft on offer, it's barely a ripple. Even when a bit more energy shows up around the 16th and 17th, that combined energy climbing to 184 (moderate), the wind is onshore and messy, making it rotten. The setup here is a beach and reef, so a lot of these bigger, onshore days just look like they'd be more fun for a kite surfer than a paddle surfer.
We've got a proper quiet spell from the 19th right through to the 22nd, with hardly any swell to speak of. Don't get excited.
The real story starts on the 23rd of September. That Wednesday morning the swell starts to build, and by Wednesday afternoon, it's on. We've got a clean 5 ft NE swell (combined energy of 678 – that's moderate to strong) with light offshore winds from the SW. That's the standout window – the best of the whole period. The swell direction is NE, which is a touch off the optimum ENE here, but it'll still wrap in. Expect very good surf conditions. This swell hangs around through to the 26th, with solid 5 ft to 6 ft surf and clean, offshore or glassy conditions. The 26th looks like a gem, with Saturday afternoon going totally glassy on that 6 ft ENE swell. Keep in mind, once you're over 5 ft, it's getting a bit much for beginners, so this late burst is mostly for the intermediate and up crew. But honestly, it’s worth the wait.
So, it's a whole lot of nothing for a long spell, but that final week of September is promising. Keep an eye on the forecasts. This is Rusty, signing off.
