The Lowdown
Gutted, folks. I’ve been staring at the charts for Octagon House (Octagon) and it’s a bleak picture for the next couple of weeks. We’re looking at a long stretch of tiny, weak surf, with barely a pulse of energy showing up. The swell direction is all over the place, mostly from the south and southeast, which is a bit off for this spot – it really wants that southeast energy to light up. That first week is a total write-off.
The water temp this Sunday morning is sitting at 87°, which is a good degree warmer than usual for this time of year – you’ll definitely notice that.
From Sunday the 2nd right through to at least the 16th, it’s a flat spell. We’re talking waves in the 1ft to 3ft range, with weak combined energy values, mostly in the teens and twenties, maybe reaching the low 40s on the 9th and 10th. The periods are short, mostly around 5 seconds, which is just windswell junk. It’s not going to be worth paddling out for. The winds are a constant problem too – cross-onshore and onshore for most of it, chopping up what little texture there is. There’s a morning on August 3rd with light offshore wind, but with a 1ft swell on a 4-second period, it’s just not happening.
A few days do have slightly better energy, like the 3ft on the morning of the 6th and again on the 9th and 10th, but the direction is still poor and the winds are onshore. This is a run where the forecast is reliable because it’s just consistently bad. It’s the kind of flat spell that makes you wonder if the ocean forgot its job. For the first week at least, you might be better off with a kiteboard if you’re desperate for a session, because the paddle surfing is a no-go.
The second week doesn’t offer any hope either. The swell stays tiny, the periods stay short, and the winds stay messy. It might ease slightly, but there’s nothing on the horizon that suggests a proper pulse of swell. This is a blank run for the area. It happens. We just have to sit tight and wait for the ocean to wake up.
Stay patient.
Rusty.
