The Lowdown
Alright, let’s break it down. For the next week and a half at Sebastian Inlet-Third Peak, it’s mostly flat or tiny. The waves are barely a foot and a half or less, with short periods, and the energy is weak—most days in the teens or twenties. There’s a big dry spell: from Wednesday the 2nd through Sunday the 7th, it’s all poor surf, with onshore or cross-off winds and hardly any swell.
The first decent chance comes Tuesday the 8th of September. The morning shows about 3ft from the NE, with an 8-second period, and the energy hits 121 (moderate). Winds are light offshore from the WSW, so the surf will be clean. It’s not big, but it’s the best we’ve got. The break is a beach/jetty, exposed to the NE, and the swell direction is right on the money. Crowds are often here, so you won’t be alone. This is the standout window for the whole 16 days.
Thursday the 10th also has a clean morning: about 2ft from the NE, 10-second period, light offshore wind from the SSW, and energy at 105 (moderate). Another small but rideable option. After that, it’s back to tiny waves and poor conditions. By Wednesday the 16th and Thursday the 17th, we’re down to less than 1ft with glassy conditions but no power.
Water temp is about average for early September, so it’ll feel normal.
Bottom line: Tuesday morning the 8th is your best shot. It’s not pumping, but it’s the only session where the wind and swell line up. The rest of the 16 days is mostly flat or junk. With this small swell and onshore wind, it’s more of a kite-surfing setup than a paddle-surfing one on most days.
