The Lowdown
Right then, Rusty here. Let’s have a look at what’s on offer for Sebastian Inlet over the next couple of weeks.
To be straight with you, the next week and a half is a write-off. We’re looking at a long, flat, and frustrating stretch from Wednesday the 9th of September right through to Monday the 21st of September. The swell is tiny, mostly under 3 ft, and the wind is messing it up with a cross or cross-onshore breeze. The combined energy of all swells directed here stays weak, barely scraping into the double digits at times. It’s not surfable, plain and simple.
Then, things finally start to change. On Monday the 21st of September, we get a pulse of NE swell. Monday morning shows 5 ft at 10 seconds from the NE, which is a proper groundswell. The combined energy jumps to 401 (moderate). The downside? The wind is cross-onshore and the conditions are choppy. It’s a bit of a mess, but at least there’s something to look at. By Monday afternoon, the swell builds to 5 ft with a period of 11 seconds, and the energy hits 617. Still, the wind is cross-onshore and choppy, so it’s not clean.
The standout window is Wednesday the 23rd of September through to Thursday the 24th of September. Wednesday morning sees a solid NE swell of 6 ft at 10 seconds, with a combined energy of 1060 (strong). The wind is cross-shore, which gives a bit of a chop, but it’s a lot better. The swell is over 5 ft, so it’s getting a bit too big for beginners, but it’s good for intermediates. By Thursday morning, the wind turns cross-offshore from the SSE at 16 mph, and the conditions go clean. The swell holds at 6 ft from the NE, 10 seconds, with combined energy of 1058. This is the best on offer. The swell direction is bang on the optimum for this spot, the size is punchy, and the wind is offshore. It’s going to be quality. Expect crowds at Sebastian Inlet-First Peak (Florida) because it’s always popular, and this is the best window.
Keep in mind, the swell is long period for a beach/jetty setup, so it might break a little straight at times, but the inlet structure should help. The water temperature is sitting at 83°F, which is about average for this time of year.
So, to sum it up: the first 12 days are a flat, frustrating nothing. The real action is on the 23rd and 24th of September. That’s your window. Thursday morning is the pick of the run.
Rusty.
