The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking for Sebastian Inlet–First Peak.
Right off the bat, I gotta be straight with you: it’s a tough stretch. For the next week or more, we’re looking at a whole lot of nothing. Tiny little 0.7ft to 1ft windswell with hardly any energy (15) is about all that’s on offer through the end of August. The water’s sitting at a warm 85°, which is about normal for this time of year. You’ll get some clean mornings, especially on the 20th when that WNW cross-offshore breeze kicks in, but it’s so small you’d be lucky to get a ride.
We finally see a flicker of life starting on Wednesday morning, the 26th of August. Swell bumps up to 1ft, but check this out—the period jumps to a very long 16 seconds. That’s proper groundswell energy, even if it’s small. The combined energy sits at 54. The morning’s clean with that light cross-offshore wind from the south, so it’s surfable, but very ordinary. That afternoon, the sea breeze messes it up.
Then Thursday the 27th of August morning, things get a little more interesting. We’ve got 2ft of east swell with a solid 13-second period, energy hitting 108 (moderate), and a clean offshore breeze from the SSW. That’s the best-looking window in this whole outlook. Still small, but clean and with enough push to make the jetty work. It is very consistent here, so if you’re keen, that’s your session.
The following days stay small, with occasional hints of a pulse—like the 30th of August morning glassy conditions and 2ft east swell (energy 102)—but the afternoon winds from the southeast chop it up. A few mornings offer that glassy or offshore feel, but the wave height never really gets above 2ft through the end of the forecast.
There’s a gap of almost no real surf until that Thursday the 27th, so don’t hold your breath before then. For the second week, it stays tiny and uninspiring. The best bet is that Thursday morning session: clean, little 2ft east swell with decent period. Not a standout for size, but for quality in a flat spell, it’s the only real option.
Keep your expectations low and your eyes on the wind.
Rusty.
