The Lowdown
Alright, I’m looking at the next two weeks here at Sebastian Inlet-Third Peak, and I gotta be straight with you... it’s pretty flat. There’s nothing on the horizon that’s gonna get the heart pumping. We’ve got a solid run of tiny, weak, and mostly messy conditions, with only a few brief windows of clean glass.
Kicking off Friday August 21st, we’ve got tiny 1 ft swell from the east, with a short period of 8 seconds. The combined energy is a weak 13. Mixed clouds and a light WSW wind keep things clean in the morning, but it’s just not enough push to ride. The afternoon turns risky with storms and a cross-onshore breeze chopping it up. Water temp is sitting at 85°, which is pretty normal for this time of year.
Saturday August 22nd stays poor – morning is clean with a cross-off wind, but still only 1 ft and 9 second period, 20 energy. Afternoon picks up a tiny bit to 2 ft from the ESE, but the wind swings cross-shore at 12 mph and it gets messy. Not worth paddling out.
Sunday August 23rd gives us a morning glass-off! NNW wind, 3 mph, dead calm – the water’s a mirror. But the swell is only 1 ft, 8 seconds, and 18 energy. It’s a tease. If you’re desperate for a float, you could sit out there, but you won’t be catching anything.
Monday August 24th through Wednesday August 26th are more of the same – tiny surf, often glassy mornings, but never enough size. The afternoons are all cross-onshore and choppy. The only thing to note is Wednesday August 26th afternoon has a weird 0.3 ft swell with an 18-second period – that’s a really long period but no height, so it’s just a ghost.
The end of the month and into September doesn’t get any better. Swell heights stay between 0.7 ft and 2 ft, with periods mostly under 10 seconds. The combined energy finally cracks 100 on Friday August 28th afternoon – 112 – but that’s with a 2 ft east swell and a cross-onshore wind. The wave comment says “poor surf conditions” for every single record. The 2 ft pulse on Sunday August 30th afternoon is the biggest in the whole run, but it’s messy and short-period.
Honestly, this is a tough stretch. The break is exposed and consistent, but the swell just isn’t delivering. For a beach/jetty setup like this, with such small, weak energy and frequent onshore winds, it’s more of a kiteboarding window than a surfing one. I’d say leave the boards at home and check back in a week – forecasts can change, and it’s rare for this area to stay this flat for long.
