The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook is a tough one for Octagon House. It’s an exposed SE-facing spot, pulling in tiny swell from the southeast, but the whole 16-day window is pretty flat. The water temp is about average for the time of year, nothing wild there.
We start off on Monday, August 3rd, with a glassy morning but the swell is only 1 foot from the SE, with a weak 6-second period and the combined energy is a measly 13 – that’s barely a ripple. It’s poor surf conditions. The afternoon kills it with a 12 mph onshore wind.
Tuesday the 4th through the rest of the first week is all the same story: tiny swell around 2 to 3 feet, short period, and the wind is either cross-on or onshore. The combined energy stays in the teens and low 30s, which is just weak. There’s a risk of thunderstorms on the 6th and 7th. Nothing to get excited about.
The second week, from August 10th to the 18th, doesn’t improve. The swell stays tiny, bumpy, and the combined energy peaks at just 73 on the 13th – still moderate but with poor winds. The very last day, August 18th, gives us a 0.3 foot swell with a 12-second period, which is a long period but there’s no height to push that energy into anything rideable. The energy is only 16.
Honestly, there’s no standout period here. Not one day offers clean, rideable waves. The swell is too small, the wind is mostly bad, and the consistency is there but the quality is zero. If you’re a beginner, it’s too flat for even a longboard. For the rest of us, it’s a frustrating blank run. For the area, this kind of flat spell is normal, but forecasts can change, so keep an eye on it.
Rusty.
