The Lowdown
Alright, Rusty here. I gotta level with you – this stretch is a total dud for the Octagon House spot (Octagon). The whole 16 days is looking flat, grumpy, and not worth a second look. The water's sitting around 86°F, a solid couple degrees warmer than normal for this time of year – feels like a warm bath, but that's the only highlight.
From the start, Saturday the 8th, all the way through to Friday the 15th of August, it's a complete write-off. Swell heights barely scrape 3ft, and the energy behind it is weak – mostly single and double-digit numbers (7 to 114) – so there's no grunt. The wind is locked in a brutal cross-onshore pattern, tearing up the tiny waves into a choppy, messy stew. Not worth getting wet for.
Into the second week, Saturday the 16th to Saturday the 23rd of August, and it's the same sad story. Tiny swell, most of it under 3ft, with real short periods (4 to 7 seconds) feeling like pure wind-slop. The energy stays pathetically low, in the teens and twenties. That one morning on Friday the 21st of August finally goes clean with a light offshore from the NW, but you're still stuck with a gutless 1ft wave. You'd be doing more scratching than riding. Honestly, with the constant onshore wind and that weak, blown-out swell on a beachy setup, this looks more like a kiteboarding zone than a surf spot for the coming weeks. Leave the board in the car. It's a total blank run around here. Things can change, but right now, the Octagon is serving up nothing.
Rusty.
