The Lowdown
Alright, Rusty here. Let me tell you straight up, it's a tough run ahead for Sebastian Inlet-Third Peak (beach/jetty). I'm looking at the next 16 days and, honestly, the surf is flat and pretty much a write-off right through to mid-September. There's nothing on the table that I'd call a good session.
We start off with small, weak windswell. Tuesday the 1st kicks things off with some knee-high waves around 2 feet from the east, but that east-northeast breeze is cross-on at 6 mph, killing any chance of clean conditions. The combined swell energy is a weak 49, and it just doesn't look appealing at all.
The pattern doesn't improve. Throughout the first week, we're stuck with tiny waves—1 foot to 2 feet—and the wind is all over the place: onshore, cross, or cross-onshore. There's a brief moment on the morning of Saturday the 6th where the wind goes light offshore, but with only 1 foot from the east, it's barely a ripple. The combined energy drops to a pathetic 12.
There's a slight bump in size around the 8th and 9th, with swell hitting 3 feet to 3 feet from the northeast, but the wind is onshore at 12-16 mph, delivering rough, choppy conditions. The combined energy climbs to 97 on the 8th afternoon, but it's messy junk.
From there, it fizzles back to tiny 1 foot to 2 feet surf for the second week, with onshore or cross-onshore winds and periods of rain and thunderstorms. The combined energy stays well under 100. There's not a single standout window in this entire 16-day stretch.
Because this spot is exposed to the east-northeast and is a beach/jetty setup, with poor surf quality and consistent onshore wind, the setup looks more interesting for kite surfing than paddle surfing during the stronger wind days. For us surfers, it's a blank run. It tends not to stay poor for long around here, but this one's a real bummer.
Rusty.
