The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for our stretch of coast.
To be honest, the outlook for the next couple of weeks is a real struggle. We’re looking at a long, flat spell with nothing rideable for the entire 16-day window. There’s just no energy out there for us. It’s a tough run, but sometimes that’s just the way it goes around here – the ocean needs a good kick to get moving again, and it’s just not happening.
The only break in the mix is Octagon House. It’s a fairly consistent beginner-friendly spot, exposed to the southeast, which is where the little bumps are trying to come from. But the combined swell energy is weak, sitting mostly between 12 and 58 (moderate wave energy at best, but for us it’s still flat). The swell heights are tiny – peaking at a mere 3ft, with periods as short as 4 to 7 seconds, which is just windswash. That’s not going to wrap in with any sort of shape.
The water temp is sitting around 87°F, which is about 2°F warmer than average for the time of year – a touch balmy, but nothing too crazy.
Wind is the only other story here. Most days it’s cross-onshore or onshore, with the occasional lighter cross or cross-off breeze on a few mornings – like on Tuesday the 18th of August when we get a clean, cross-offshore 6 mph wind from the WSW. But it doesn’t matter, because there’s no swell to clean up.
There are no standouts. No surf worth paddling for. It’s a long, dry spell. If you’ve got a kite, the bigger winds might be more fun for you, but for a surfboard, this is a blank. Keep an eye on the charts though – it never stays this quiet forever.
