The Lowdown
Alright, surf’s looking pretty grim out there for the next couple of weeks, and I gotta be straight with you. We’ve got a solid stretch of flat, weak, and messy conditions on the horizon. There aren’t any good surf options in this 16-day window, so if you’re jonesing for a wave, you might wanna find another hobby for a bit.
The water at Sebastian Inlet-Third Peak is running about 81°, which is a bit colder than normal for this time of year. Not crazy, but you’ll notice it.
So, here’s the rundown. We start off with a real bummer. Tuesday the 4th has a tiny 2ft east swell at 7 seconds, but it’s got a cross-shore breeze on it and the energy is weak (28). It’s just not happening. Wednesday the 5th is even smaller, with 1ft on tap and just a light cross-shore breeze. You’d be fighting for scraps.
We go through Thursday and Friday with the swell trying to nudge up a bit, but it’s still poor. Thursday has 2ft at 5 seconds and a cross-onshore wind. Friday morning sees a jump to 4ft, but it’s coming with a moderate cross-onshore breeze, making it choppy and messy. The energy gets a bit more moderate, reaching 111, but the quality is just not there.
The weekend isn’t much better. Saturday the 8th has the biggest swell of the whole run, with 4ft at 8 seconds and a moderate energy reading of 184. But it’s still cross-shore, and the period is short, so it’s going to be a jumbled mess. Sunday is similar, but slightly smaller.
From Monday the 10th onward, it’s a slow bleed-out. Swell heights drop back down to 2ft and then just keep fading. There’s a moment on Tuesday morning the 11th with a light cross-offshore breeze and clean conditions, but the swell is only 1ft at 6 seconds. It’s glassy but there’s nothing to ride.
We then hit a real dead zone from the 12th to the 15th, where the swell drops to 0.7ft to 2ft of chopped-up slop. The winds are mostly onshore or cross-shore, and there’s just no power.
The week after that, from the 16th onward, sees the swell staying tiny, a little pulse of 2ft on the 19th with a NE direction and 6-second period, but it’s blown out by a moderate cross-onshore breeze.
Look, the inlet is consistent as a break, but it’s just not breaking with any size or shape in this forecast. With these tiny waves and prevailing winds, the setup looks more interesting for kiting than paddle surfing, to be honest. It’s a blank run, which happens. The forecast can change, and these things tend not to stay this bad for long. But right now, leave the board in the car.
