The Lowdown
Alright, Rusty here, let’s take a look at what’s cookin’ for Sebastian Inlet-First Peak over the next couple of weeks. Gotta be straight with you – it’s a quiet spell. We’re not looking at any standouts here, just a whole lotta small, ordinary conditions.
The water’s sitting at 83°, which is a touch cooler than we’d normally expect for this time of year, about a degree and a half off. It’s not a shocker, but you’ll notice it if you’re used to it being a bit toastier.
We kick things off Tuesday afternoon, August 11th, with tiny 1ft swell out of the ESE and a short 6-second period. The combined energy is a weak 21, and with a cross-onshore breeze, it’s choppy and not worth paddling out for. Wednesday the 12th brings even smaller 0.7ft waves in the morning with a glassy, clean look thanks to a light offshore, but it’s just too small to do anything with. The whole first week is like that – a mix of tiny 0.7ft to 1ft swells, mostly from the east or southeast, with short periods and mostly cross or onshore winds. The energy readings stay low, hanging between 5 and 34. There’s a clean morning here and there, but the swell just isn't there.
The only time things get slightly interesting is mid-week the following week. On Wednesday morning, August 19th, we see a bit more life – 2ft swell from the east with an 11-second period, giving it a bit more shape. The combined energy bumps up to a moderate 60, and the wind is a clean cross-offshore. That afternoon, it goes glassy. But even then, we’re only calling it “surfable but very ordinary.” For a spot that’s “very consistent,” this is a flat run. The rest of the second week falls back into the same pattern: small swells, short periods, and a lot of cross-onshore chop. This is a stretch where you’d be better off checking the forecast again in a few days.
Honestly, for this entire 16-day window, there’s nothing that stands out as a good session. The swell just never gets above 2ft, and the periods are short, so don’t expect any power. It’s a blank run for the area, plain and simple.
Rusty.
