The Lowdown
Alright, folks, Rusty here. I'm not gonna sugarcoat it; the next couple of weeks are a test of patience. The start of this forecast is plain rough, with a long stretch of poor conditions and junky surf. There's a big nothing-burger for over a week, so don't get your hopes up for any quick relief.
From Friday the 14th, we're looking at small swells with terrible onshore winds. We see 1 to 1.6m swells from the east and southeast, but it's all chopped up and messy. It's not worth your time. That poor run just keeps on going, day after day, with the wind never giving us a break. There is a small window on the morning of Tuesday the 19th where the wind goes glassy, and the waves are a mere 0.8m. It's clean, but there's just no power in it, and the energy is weak. That's just a knee-high dribble for someone with a log.
From the 20th onward, the swells die way down, and the wind stays bad. This whole stretch of practically nothing lasts until the morning of Sunday the 24th. That's a solid ten day wait.
Now, for the payoff. The first glimmer of hope comes on Monday morning, the 24th of August. It's small, only 0.7m, but that’s a clean southeast groundswell with a very long 16-second period. The wind is glassy. After all that wind and chop, this is going to look clean as a whistle. It'll be small, don't get me wrong, but the vibe will be right.
The one to circle in red is the morning of Wednesday the 26th of August. The swell is up to a proper 1.8m from the southeast with a 13-second period, and the wind is offshore from the north-northwest at just 3 mph. This is the cleanest, most powerful surf of the whole forecast. The wave energy is going off at 1207, which is a serious jump. The conditions are going to be absolutely firing for the experienced crew. This is not for beginners, this is for the guys and gals who know their way around a steep face. Get there early because the afternoon wind will ruin it.
The Tuesday morning before that is also a decent option with a 1.6m southeast swell and clean offshore winds, but Wednesday is the call. The water temperature on the 14th is 82°, which is about normal for this time of year. So, it's a long grind, but there's a couple of good days on the horizon, and Wednesday the 26th is the big one.
Rusty, out.
