The Lowdown
Alright, Rusty here. Let's take a look at what's on the menu for Octagon House over the next couple of weeks.
Well, I gotta be straight with you – it’s looking pretty bleak for the next little while. We’ve got a real flat spell on our hands. The first surfable day I can see is for Monday morning, August 31st, but honestly, we’re talking about a tiny 0.3 ft SE windswell with a period of just 9 seconds. The combined energy is a measly 4, so it's barely a ripple. The water's a touch warmer than normal at 87°. Conditions are clean with a light cross-offshore breeze, but there's just no power to work with. The rest of that day and all through the first week of September into the second, we’re looking at tiny, weak waves and mostly onshore or cross-onshore winds. You'll be seeing a lot of "poor surf conditions" notes in the log.
We finally see the energy tick up a little around Thursday, September 10th, with the swell pushing to 3 ft from the SSE, but the period is a short 5 seconds and the wind is a moderate cross-onshore, making for choppy conditions. The combined energy hits 41, which is still weak. That pattern of cross-onshore wind and small, weak swell pretty much continues straight through to the end of the forecast on Tuesday, September 15th.
There isn't a single standout session in this entire 16-day window. We're looking at a two-week gap with no real recommendations. The only slight glimmer is Monday morning, September 7th, where we get a brief window of glassy conditions with the wind going WNW at 3 mph. But even then, the swell is still a pathetic 1 ft. Honestly, with this constant small, weak swell and onshore wind, you'd probably have more fun on a kite than a paddle board right now. It’s a tough run, but that’s the way it goes sometimes.
Rusty.
