The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days at Walton Rocks (Power Plant) are a tough pill to swallow. The whole outlook is a flat spell, with barely a ripple to get excited about. We’re looking at a long stretch of weak, poor surf conditions, so don’t be holding your breath for any waves worth paddling for.
Right off the bat, from Thursday the 3rd through the weekend, we’ve got tiny swell – barely 1ft to 2ft from the east, with short periods under 8 seconds. It’s just windswell, no energy behind it. The combined energy is weak, sitting at 30 or less for most of this time. Thursday morning starts glassy, but with a risk of thunderstorms, it’s not going to be worth the trip. Friday morning might be clean with a light cross-off breeze, but with only 2ft and that short period, it’s a total non-starter.
The middle of next week, around the 9th and 10th, we see a tiny bump – swell height hits 2ft from the ENE, and the combined energy climbs to 102 on Wednesday morning, which is still only moderate. But the wind is cross-onshore at 15 km/h, chopping it up. The period is still short, around 8 seconds, so it’s not going to produce any shape worth mentioning.
We go back into a total lull from the 11th onwards. Swell drops to 0.7ft to 1ft, and the combined energy is in the single digits or teens – basically nothing. There are a few glassy mornings, like Saturday the 12th with a light westerly, and Tuesday the 15th with dead calm, but those tiny 0.7ft waves won’t even break. The 16th morning offers a clean, offshore breeze from the southwest, but again, it’s only 1ft of east swell. It’s a tease.
The water temperature is a warm 85°, which is about average for the time of year, so at least you won’t freeze while you’re floating around doing nothing.
Honestly, there’s not a single standout session in this whole 16-day window. The conditions are poor, the swell is flat, and the wind is mostly onshore or cross. This is a blank run for Walton Rocks. If you’re desperate for a paddle, go for a glassy morning, but don’t expect to surf. The setup looks more interesting for a kayak than a surfboard right now.
Rusty.
