The Lowdown

Alright, Rusty here. Let's talk about what's coming up for Sebastian Inlet-Third Peak. This is a beach and jetty setup that's exposed to the swell, and it's a consistent spot, so it's a bit of a tease when the ocean goes quiet.

Honestly, we're looking at a pretty flat spell to kick things off. The first week and a half are a real struggle. From Saturday, August 8th, right through to the morning of Tuesday, August 19th, the surf is a dud. We're talking about weak, small waves with poor conditions. The combined swell energy is in the cellar, mostly under 100 (like 17, 37, 82), so there's just no power in the water. The wind is mostly cross or cross-onshore, and the swell is a short-period 6 to 8 seconds, which is just wind chop, not real surf. A few mornings, like Tuesday the 11th and Thursday the 13th, you get a glassy surface, but with waves barely 0.7ft to 1ft, there's nothing to ride. It's a real bummer. You'd be better off with a kiteboard given the wind and weak waves, but even then, it's a long stretch of nothing.

Then, on the morning of Wednesday, August 19th, we finally get a glimmer of hope. The swell jumps up to 2ft from the east, and the period stretches to 13 seconds. That's a proper groundswell. The combined energy pushes to 116 (moderate), and with a light cross-offshore wind, it's clean. It's not firing, but it's surfable—ordinary, but rideable. The afternoon gets messy again with the wind shift.

Thursday, August 20th, the morning is a standout. The swell holds at 2ft from the east, with a 10-second period, and we get glassy conditions. The combined energy is 90. It's small, but it's clean, and it's the best we've seen in a while.

The real pick of the whole 16-day window, however, is the morning of Saturday, August 22nd. The swell is 2ft from the east, with a 12-second period, and the combined energy is 98. The wind is light and cross-offshore from the south, making for clean waves. It's not a big swell, but it's the best combination of size, period, and wind we're going to get. The direction is east, which is right in the optimum range for this spot. It's a morning session for the patient crew.

And then to wrap it up, the morning of Sunday, August 23rd looks similar—2ft east swell, 12-second period, 115 energy, and glassy conditions. Another good one for the early birds.

So, the whole story is a long flat patch, then a few promising mornings in the last few days. The best of the bunch is the morning of Saturday the 22nd. It's not a classic, but it's clean, and it's all we got. Keep an eye on it.

Rusty.
