The Lowdown

Alright folks, Rusty here. Let’s get into it. We’re looking at the next couple of weeks, and if I’m being honest, it’s a pretty grim stretch. There’s a long, sad gap right at the start with no real surf to speak of. The first worthwhile bump won’t show up until Tuesday, August 4th, and even then it’s a real struggle. The whole 16-day window is thin, with consistent but small energy and a lot of wind messing things up.

The first day that’s even worth paddling out is Tuesday the 4th, and that’s being generous. Sebastian Inlet-Third Peak is a beach/jetty setup that’s exposed to the swell. The morning starts with a light offshore from the SSW, but the swell is a measly 2 ft from the East, with a combined energy of just 31 (weak). It’s clean, but tiny. The afternoon gets a bit better with a brief window of glassy conditions and the swell dropping to 1 ft, but the energy bumps up to 41 (still weak). The water temp is about average for this time of year, nothing weird. It’s surfable, but you’ll be fighting for scraps.

The middle of the week is a write-off. Wednesday and Thursday the 5th and 6th are plagued by cross-onshore winds from the ESE and ENE, making everything choppy and messy. Swell heights hover around 2 ft to 3 ft, but with short periods of 5 seconds, it’s just wind slop. The energy gets up to 64 on Wednesday afternoon, but it’s not the kind of energy you want—it’s all chop. Honestly, this setup looks more interesting for a kite session than a paddle surf, with the wind and small, poor-quality waves.

The only real standout that might get a little bit of a pulse is Saturday the 8th. The morning has a clean 2 ft swell from the East with an 8-second period, and the energy is 73 (moderate). The wind is light onshore from the NE, which isn’t ideal, but it’s the biggest energy we see in the whole window. The afternoon gets choppy again with cross-onshore winds. It’s not great, but it’s the best on offer. Since it’s a consistent break, crowds are likely, especially on a weekend.

After that, it’s a slow fade. The second week is a total washout. From the 9th onwards, swell heights drop back to 0.7 ft to 2 ft with weak energy readings mostly in the teens and twenties. There are a few glassy moments on the 9th, 13th, and 16th, but the wave height is just too small to do anything. You’ll be bobbing around on a lake. Periods don’t get above 8 seconds, so there’s no real push. It’s a long, flat spell.

Overall, this is a tough forecast. If you’re desperate, Saturday the 8th at Sebastian Inlet-Third Peak is your best bet, but don’t expect much. The rest of the time, leave the board at home.

Rusty.
