The Lowdown
Alright folks, Rusty here with a look at what’s coming up for Sebastian Inlet-First Peak. I’ve got to be straight with you – it’s a lean run ahead. The forecast shows a long gap with hardly anything worth paddling out for. For the next 16 days, there’s no proper swell to get excited about, and the conditions are mostly messy. We’re looking at a stretch of small, weak waves with a lot of onshore wind, so don’t expect much.
Sunday, September 13th kicks off with just tiny 1.0 ft swell out of the east, period at 9 seconds. The morning is glassy and calm, but the combined swell energy is weak at just (21), and it’s labeled as poor surf. By afternoon, a cross-on breeze kicks up, and it’s not worth it.
Monday, September 14th is more of the same – glassy morning with 1 ft east swell, but it’s still small and weak (25). Afternoon brings cross-on wind and a risk of storms.
The pattern drags on. Tuesday, September 15th stays small, and by the afternoon, a 12 mph onshore wind makes things choppy. The swell ticks up a little on Wednesday, September 16th – 5 ft from the northeast, but it’s a short period windswell (7-8 seconds) and the wind is blowing straight on at 19 mph. That’s raw, bumpy, and not fun. The energy jumps to moderate (272), but it’s a messy onshore mess. This continues through Thursday, September 17th with 4 ft swell and onshore wind.
Finally, Friday, September 18th gives a tiny window. The morning goes glassy with a 2 ft northeast swell. It’s still small and the period is short (8 seconds), but the combined energy is low (99). The call is “surfable waves but very ordinary conditions.” It’s not a standout, but it’s the best we’ve seen in a week. If you’re desperate, you might find a knee-high wave.
After that, it fades again. Saturday, September 19th has a clean morning with light cross-off wind and 2 ft swell, but it’s weak (47). The afternoon turns glassy but the swell drops to 2 ft. Sunday, September 20th has offshore wind but the swell is tiny at 1 ft (18). The rest of the week into the end of September stays small – mostly under 3 ft, with onshore or cross-on winds and poor conditions. The only other day with a “surfable” tag is Monday, September 28th – a 2 ft east-northeast swell with a light cross-off breeze and clean conditions (69), but again, it’s knee-high.
Bottom line: there’s no proper swell on the horizon. The waves are small, the period is short, and the wind is mostly junk. The best bet is the morning of September 18th if you want to wet your board, but keep your expectations low. The inlet setup here is very consistent for producing something, but even it can’t pull a rabbit out of the hat this time. Don’t hold your breath – forecasts can change, but this run looks quiet.
Stay patient, Rusty.
