The Lowdown
Alright folks, Rusty here, and I'm not gonna sugarcoat it – we're looking at a whole lot of flatness for the foreseeable future. There's a long dry spell before anything even thinks about showing up.
We're talking about Sebastian Inlet-First Peak. The first week is a write-off. From Tuesday, August 11th, all the way through to Wednesday, August 19th, the swell is laughable – ankle-biters at best, around 0.7ft to 1ft with short periods. The energy numbers are pathetic, reading 18, 10, and even 5 (weak energy). The mornings are clean but empty, and the afternoons get a bit of a cross-shore breeze that chops up the surface. It's all "poor surf conditions" with zeros on the scoreboard.
Things finally perk up on Thursday, August 20th. The morning turns glassy, and while the swell is still small at 2ft from the E, the period stretches to 11 seconds – a nice long groundswell. The energy climbs to 82 (still weak overall, but it's the best we've got). The water temp is 83°, which is a bit colder than normal for the season, so don't expect bathwater.
The one true standout in this whole 16-day window, the only time I'd bother taking a look, is Wednesday, August 19th in the afternoon. The combined energy hits 178 (moderate energy). You've got a 3ft swell from the E with a 12-second period – that's a proper groundswell with some grunt. The wind is cross-onshore, so it won't be flawless, but that's the biggest and most energetic swell of the entire forecast. It's still manageable for most surfers. If you're desperate, that Wednesday afternoon is your best shot. The next morning, Thursday, August 20th, is the only other time that gets a "surfable" nod, but it's a 1 out of 10, so don't get your hopes up.
For most of these days with tiny swell and onshore winds, this inlet setup looks like it's built more for kite surfing than paddle surfing. There's just not enough power for a decent wave.
Rusty.
