The Lowdown
Alright folks, Rusty here. Let's talk about what's happening at Sebastian Inlet-First Peak for the next couple of weeks. I'll be straight with you: this forecast is a tough pill to swallow. We've got a long, dreary stretch of flat, poor conditions before we see any real hope on the horizon.
Right from the start, it's flat. Saturday the 12th we've got a tiny 1ft swell from the east with a short period. Wave energy is weak. It's a risk t-storm morning with a light offshore breeze, but it's still just poor surf. Sunday the 13th morning is glassy, flat, and calm, but that 1ft east swell isn't doing a thing. This same story of tiny, weak, and poor surf carries on for days.
Then Wednesday the 16th shows a little bump. The swell hits about 4ft from the NE, period is still short, and energy gets moderate. But look at the wind – onshore and howling at 19 mph. It's going to be a blown-out mess at this beach/jetty setup. This pattern of onshore junk continues through the end of the week.
Now, the best we've got is a promise way down the line. On Friday the 26th of September, we start seeing something interesting. The swell is up to 4ft from the NE with a very nice long period of 11 seconds. That's real groundswell energy. But here's the killer: the wind is forecast to be cross-onshore at 22 mph. It's gonna be lumpy and bumpy.
The standout window, if you can call it that, is Saturday the 27th of September morning. Swell holds at 5ft from the ENE with a very long period of 12 seconds. That's proper groundswell, and the energy is very strong. This is the biggest and most powerful swell of the whole 16 days. But again, we are cursed with a fresh cross-onshore wind at 22 mph, so it's going to be lumpy and rough. At 5ft, this is getting into the size that will be tough for beginners, and the onshore wind will make it a battle. The water temp is around 85°, about average for this time of year.
Given the persistent onshore winds with these stronger swells, the beach/jetty setup looks more interesting for kite surfing than paddle surfing.
Rusty, signing off.
