The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the menu for the next couple of weeks. To be straight with you, there’s not a lot to get excited about. The swell window is barely open, and we’re looking at a long dry spell until the very end of the forecast. We’ll start with the only spot that’s even on the radar: Octagon House (Octagon).
Right now, Thursday the 10th, the ocean is flat with a tiny 1ft ripple from the ESE moving at a sluggish 4 seconds. The water is sitting at 87°, which is a touch warmer than normal for this time of year – nice for a dip, not so much for a surf. The combined energy is weak (7), and honestly, it’s a no-go.
Friday the 11th through to Wednesday the 25th is a grim run. The swell never cracks 3ft. You’ll see the odd 3ft pulse from the SSE or S around the 12th and 14th, but the period is short (5-6 seconds) and the winds are mostly cross-onshore or onshore, making for poor, chop conditions. The combined energy peaks at a very moderate 59 on the 17th, but that’s still attached to a messy 3ft cross-on shore slop. Even when the wind goes glassy or offshore on the 18th and 19th, the swell is down to 2-2ft. It’s just not doing anything.
There’s a small glimmer at the very tail end. On Thursday the 25th, we get a 3ft swell from the East. The period nudges up to 5 seconds. The wind is a gentle cross-shore. That’s the closest we get to something rideable, but with the combined energy sitting at 58, it’s still a pretty weak affair. For a beginner spot like this, that’s the only window that might be worth a look on a log.
In short, it’s a quiet period. We’re talking over a fortnight of marginal to no surf. If you absolutely need to get wet, keep an eye on that Thursday the 25th for the biggest of the small bumps. Otherwise, it’s a time to wax your boards and wait.
Rusty.
