The Lowdown
Alright folks, Rusty here. Let’s break down what we’ve got on the horizon. It’s a grim stretch ahead, I’m not gonna sugarcoat it. We’re looking at a solid 16 days, but the first 12 days are a total write-off for any kind of decent surf. The swell is tiny, the wind is mostly cross or cross-on, and it’s just a choppy mess. You’ll be fighting a losing battle out there.
The first real glimmer of hope doesn’t show up until Saturday, the 8th of August. That morning, the stars briefly align at Octagon House. We’ve got a tiny 0.9m SSE swell creeping in, but the magic is in the wind – it’s glassy. Absolutely flat calm. That’s a rare treat. The wave energy is still weak (53), and it’s a short period of 6 seconds, so it’s not going to be a day of barrels, but for a learner-friendly spot like this, a clean, tiny wave is a godsend. The water is sitting at a warm 30°, which is a touch above average for this time of year, so you’ll be comfortable in boardies. The downside? It’s a spot that can get crowded *sometimes*, so on a rare glassy day, you might have some company.
After that one morning, it’s straight back to the doldrums. The window is so small, that’s all we get. The rest of the 16 days is just more of the same poor conditions. The energy stays weak, and the wind gets messy again. There’s nothing else to get excited about. It’s a long, tough run with a single, bright, fleeting moment.
Rusty.
