The Lowdown

Alright, this is Rusty, and I’m looking at the charts for Sebastian Inlet. I gotta be straight with you – the next couple of weeks are looking pretty flat and sad. The swell energy is just not there, and the wind is mostly wrong for what little we have.

We’ve got a real dry spell ahead. The first recommendation for a surf doesn’t really show up until the 10th of September, and even then, it’s barely a whisper. From now until then, we’re looking at a solid few days of nothing worth paddling out for. The little bumps of 0.7ft to 1ft from the ENE are just windswell with a short period, mostly under 8 seconds, and the wind is either onshore or cross-onshore. It’s just messy.

Thursday morning, the 10th, is the first time we get a sniff of something. Sebastian Inlet-Third Peak (a beach/jetty setup) will see a tiny 3ft swell from the ENE, but the period is a weak 8 seconds. The combined energy is only 92 (mild), so it’s weak. The good news is we have a light cross-offshore breeze from the SSE, which will clean things up. The water temp is sitting at 83°, which is about normal for this time of year. Honestly, it’s surfable but very ordinary – a longboard maybe, if you’re desperate.

After that, it’s back to the same story. The rest of the week and into the next offers nothing but small, choppy, onshore slop. There’s a moment on Saturday morning, the 12th, where the wind goes glassy from the SW, but the swell is only 0.7ft and from the ENE with a period of 6 seconds. That’s a lake, mate. You’d be standing on your board.

We don’t see any real improvement until Tuesday the 22nd. The morning shows a 2ft NE swell with an 8-second period, and the wind is a light cross-shore from the ESE. The energy bumps up to 69, but it’s still poor conditions according to the notes. The afternoon gets a little bigger, 3ft from the NE, but the wind swings onshore, ruining it.

To be honest, the standout session in this whole 16-day window is that Thursday morning, the 10th. It’s not great, but it’s the only time the stars align even slightly. The cross-offshore wind is a major positive for that window, making the tiny waves rideable. For a beach/jetty break like this, the NE swell direction is what it wants, but the size and period just aren't there.

It’s a tough run. The combined energy never gets past 154 (moderate), and most of the time it’s below 100, which is weak. The swell is too small for beginners to worry about, and for everyone else, it’s just a waiting game. Forecasts can change, but right now, this is a good time to wax the longboard and hope for a miracle.

Rusty.
