The Lowdown
Alright, Rusty here. Let’s call it like it is: Sebastian Inlet-Third Peak is in a funk for the next week and a half. The first chance of anything worthwhile is a long way off.
From now through the end of August, forget it. We’re looking at flat, weak waves—maybe shin-high at best—with cross and onshore winds messing things up. The water’s a warm 86°, which is about a degree warmer than normal for this time of year, feeling like a swimming pool. The energy readings are all in the low double digits or less, meaning there’s no power behind any of this. If you’re a kiter, maybe, but for paddling, it’s a big old skip.
Things start to whisper awake on the morning of Wednesday, September 2nd. The wind goes glassy, dead calm, and we get a little 0.5m swell from the east with a 13-second period. The energy is still modest, but clean conditions will make those tiny waves look a lot better than they are.
The real highlight is Thursday, September 3rd. That morning, you get a light offshore breeze from the southwest, grooming an 0.8m east swell with a 13-second period. The energy reads 220, so there’s some push behind it. Expect clean, lined-up waves at Third Peak (Florida Coast). By the afternoon, it improves: the swell hits 0.9m from the east, 14-second period, with a light cross-offshore wind. That’s your best bet. The conditions will be clean and the waves will have enough shape to make dropping in fun. This spot can get crowded often, and with a day like this, expect company.
Friday, September 4th is still rideable, with the swell holding at 1.0 to 1.1m from the east, 13-second period, and cross-offshore winds from the west. The energy is strong at 413, but the forecast says it’s a little marginal, so the waves might be a bit more disorganized than Thursday. Still worth a paddle if you missed the prime window.
After that, we’re back to a sloppy mix of onshore winds and smaller, shorter-period junk into the next weekend. The takeaway? Keep your schedule clear for the morning of September 3rd. That’s the day.
Rusty.
