The Lowdown
Alright folks, Rusty here. I’ve been staring at the charts for Sebastian Inlet-First Peak, and I’ve got to be honest with you – it’s a grim stretch ahead. The whole 16-day window is showing a persistent run of “poor surf conditions,” with scores all reading zero. There’s not a single standout session in the mix, so I’m not going to sugarcoat it.
We start off on Saturday, the 15th of August, with a tiny 0.7ft swell from the ENE, but it’s got a cross-on ESE wind blowing at 12 mph, making it choppy and messy. The combined energy is a weak 26, so there’s barely any push. The water temperature is sitting at 84°F, which is about normal for this time of year – nothing unusual there. Sunday morning, the 16th, offers a bit of a tease: a light 1.0ft E swell with a clean, offshore SW wind at 6 mph, but it’s still too small to bother with. The afternoon turns cross-shore, and the pattern just repeats day after day.
Through the rest of the first week, from Monday the 17th through to Saturday the 23rd, we’re stuck on 1.0ft swells, periods mostly around 8 seconds, and combined energy that rarely breaks 25. The wind flips between light offshore and moderate cross-shore, but the size is just not there. It’s ankle-biters at best.
The second week doesn’t offer much hope either. Around the 25th of August, we see a little bump to 2ft from the E, but the period drops to a pathetic 5 seconds, and the wind is cross-on at 12 mph. The combined energy is only 23 – that’s not a swell, that’s a ripple. By the 27th of August, we get a bit of a pulse: 3ft at 12 seconds from the E, and the combined energy climbs to 196 (moderate energy). That’s the biggest we’ll see, but the wind is still cross-on from the E at 9–12 mph, keeping it choppy and disjointed. The period is just over 11 seconds, so it’s a groundswell, but at a beach/jetty spot like this, it’ll likely break too straight and won’t offer much shape.
The final days, from the 28th to the 30th of August, stay in the 1ft to 2ft range, with periods dropping back to 6–10 seconds and combined energy petering out to between 48 and 97. The wind remains cross-on, so it’s all just a mushy, bumpy mess.
Bottom line: there’s no surf worth paddling out for in this 16-day window. The break is very consistent, but when the swell is this tiny and the wind is onshore or cross-on, it’s just a flat, choppy lake. If you’re desperate, keep an eye on the 27th of August, but even that is a long shot. For now, leave the boards in the garage. This is one of those blank runs that happens, and forecasts can change, so don’t lose hope entirely.
Rusty.
