The Lowdown
Alright folks, Rusty here. Let's be straight with you. We've had a look at what's cookin' at Octagon House, and honestly, for the next 16 days, it's a bit of a flat spell. The first real surfable day is Wednesday, August 5th, but even then it's not great.
The pattern is pretty grim: tiny, weak swell with short periods (around 5 seconds) and mostly onshore or cross-onshore winds. The combined energy of all swells directed here is a measly 17 (Wednesday afternoon), which is weak. You're looking at waves around 1.6 ft to 3 ft from the SSE or SE, with periods barely cracking 6 seconds. That's windswell, not groundswell, so it's gonna be choppy and weak.
The water temp is sitting at 86.7°F, which is a touch warmer than normal for this time of year, but that's small comfort when there's nothing to ride.
There's a big gap in the action. Nothing is worth paddling out for from Wednesday the 5th all the way through until Tuesday the 18th. It's a solid two-week stretch of small, onshore, poor surf conditions. The combined energy climbs a bit around the 12th and 13th, hitting 57 and 65, but that's still weak, and the wind is still cross-on. It's a frustrating run.
Now, the only glimmer of hope, and I mean the only one, is the morning of Tuesday, August 18th. We get a glimmer of a cross-offshore wind from the WSW at only 3 mph. The swell is still tiny at 2.6 ft from the SSE, and the period is a short 4 seconds, so it's not gonna be powerful. But the combined energy is 36, and more importantly, the wind will be light and clean. It'll be the only clean surf of the entire forecast. The water will be flat, the waves tiny, but for a beginner session on a longboard, you might be able to squeak out a few soft, crumbly walls. The crowds are "sometimes" here, so you might have it to yourself, but honestly, it's not a standout.
For the rest of the run, it's a washout. The setup is a beach, so with the onshore winds and small chop, it's more interesting for the kite surfers than us paddle surfers.
So, bottom line: if you're desperate, dawn patrol on Tuesday the 18th. Otherwise, take a break. The forecasts can change, but right now, it's a tough outlook.
