The Lowdown
Alright folks, Rusty here. Let’s get stuck into what’s on offer for the next 16 days. I’ll be honest right off the bat: the outlook is a long, flat spell with just a tiny, flickering light at the very end of the tunnel.
We’re looking at a solid stretch of quiet days. From Tuesday morning, August 4th, all the way through to Tuesday afternoon, August 18th, there’s pretty much nothing worth paddling out for. The wave energy is weak, barely cracking double digits (9 to 72) with swell heights hovering around 0.7 ft to 3 ft, and most of it is short-period, wind-affected junk. The winds are mostly cross or onshore, chewing up what little bump there is. It’s all labelled “poor surf conditions,” and that’s exactly what it looks like. There’s a real gap there of over two weeks with no recommendations.
The one and only standout, and I mean the only one, shows up on the final day of the forecast period. On Wednesday morning, August 19th, we finally get a glimpse of something. Octagon House sees a little bump of swell at 3 ft from the SE, with a period of 6 seconds. The combined energy is still modest at 85, but it’s the best we get. The real kicker is the wind – a light cross-offshore breeze from the WSW at 6 mph. That’s going to put a clean face on those waves. It’s described as “surfable waves but very ordinary conditions,” but with that wind, it’ll be the cleanest it’s been in weeks. For a beginner-friendly spot like this, that’s your window. It won’t be big, but it’ll be rideable and clean. Just don’t expect a crowd-free session, as it can get busy here sometimes.
The rest of the 16 days? A total write-off. You’re better off checking the forecast again closer to the 19th, because this is a long way out and the details could change. For now, that Wednesday morning is the only real chance to get wet.
