The Lowdown
Alright, Rusty here. Let’s talk about this stretch.
Straight up: Sebastian Inlet-First Peak is going through a rough patch. It’s a beach/jetty spot that’s exposed and very consistent for catching waves, but for this whole 16-day run, the quality is nowhere to be found. From Friday the 11th all the way through to Saturday the 26th of September, we’re looking at poor surf conditions every day, so there’s no standout session. The first week is especially flat and weak.
We start on Friday the 11th with tiny swell, only 1ft from the ENE, a period of 6 seconds, and combined energy of just 31 – that’s weak. A little cross-off wind in the morning keeps it clean, but there’s virtually nothing to ride. This flat patter holds through Saturday and Sunday, with waves running about 1ft. Monday the 14th morning goes glassy – no wind – but still only 1ft with weak energy (25). It’s clean, but you’ll be bobbing around.
As we get into the middle of the week (the 16th and 17th), the swell tries to pick up to about 3ft, but the period drops to a poor 5-6 seconds, and the wind goes onshore from the NE, messing things up. Energy climbs to 55-69 – still moderate – but the onshore breeze and short period mean it’s a mess. This onshore wind sticks around for several days, with thunderstorms likely cropping up.
The only real change in the whole 16 days happens around Tuesday the 22nd and Wednesday the 23rd. Swell size bumps up to 5ft-5ft from the NE and ENE, with periods of 6-8 seconds. Combined energy jumps to 133 and even 264 on Tuesday afternoon – that’s strong energy for a moment. But don’t get too excited: the wind is a fresh cross-onshore from the north at 18 mph, making conditions lumpy and choppy. This is bigger swell, over 5ft on the face, so it’s for experienced surfers only, but the quality is blown out. With that strong cross-onshore wind and a beach/jetty setup, this looks more like a kite surfing day than a clean paddle session.
The last few days from the 24th to the 26th drop back down to 2ft-3ft, with cleaner mornings but still onshore or cross-onshore winds. Energy is moderate (106-129) on Thursday, but the conditions never line up.
Standout: There isn’t one. If I had to pick the best of a bad lot, Tuesday the 22nd has the most size (5ft) and energy (264), but the wind kills it. It’s a no-go. We’re looking at a solid 16-day gap with no quality surf. That’s just the way it is sometimes – forecasts can shift, but right now, it’s a long wait.
Rusty.
