The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Sebastian Inlet-First Peak over the next couple of weeks.
Honestly, I gotta be straight with you—this is a tough run. The entire 16-day window is looking pretty flat and messy. There's not a single standout session in there, and the first real recommendation doesn't show up at all. We're looking at a long stretch of poor surf conditions from now all the way through the 19th of September. The swell energy is weak, mostly hanging around in the double digits (between 5 and 99), which is basically nothing. The swell is coming from a mix of east and northeast directions, but the size is tiny—most of the time it's between 0.7ft and 3ft. The period is short, mostly under 10 seconds, so it's just windswell, no real grunt.
The water temp is sitting at 83°F, which is pretty average for this time of year, so no surprises there.
The wind is the real killer. For almost the entire period, it's blowing onshore or cross-onshore from the east or northeast, 9-16 mph, just chopping everything up. There are a few rare windows of cleaner conditions—like the morning of the 7th, 8th, and 11th of September—but the swell is so small during those times (0.7ft to 1.0ft) that it's not worth getting wet.
For the first week, forget it. The second week doesn't offer any relief either. The swell picks up a tiny bit around the 14th and 15th of September, with combined energy reaching the 80s and 90s, but that's still weak, and the wind is still onshore. It's basically a week of small, choppy junk.
This is just a flat spell, plain and simple. For an exposed spot like Sebastian Inlet-First Peak, it's not unusual to have a blank run like this. The one thing I'd say is that if you're into kite surfing, that solid onshore wind and the small, choppy waves might be your thing. For paddle surfing though, there's nothing on offer.
Keep your board in the car, but don't hold your breath. Forecasts can change, but right now, there's no light at the end of the tunnel.
Rusty.
