The Lowdown
Alright, Rusty here. Let's be straight with you – this 16-day window for Sebastian Inlet-Third Peak is a tough stretch. The forecast shows a persistent run of small, weak, and generally messy surf. The best I can say is that there are a few calm, clean windows, but the swell is barely there.
We kick off on Friday, 7 August, with a 5ft east swell, but it's a short-period 7 seconds, and we've got a 16 mph onshore wind from the east. The wave energy is moderate (182), but the poor surf conditions make it a write-off. The wind stays onshore or cross-onshore through Saturday and Sunday, with the swell dropping to 4ft on Saturday and then down to a tiny 2ft on Sunday. The beach/jetty setup is exposed, but with this short-period, wind-affected swell, it's just lumpy.
The first real sign of hope comes on Tuesday, 11 August, in the morning. We get a glassy session with easterly swell of 1.0ft and a period of 7 seconds. The energy is very weak (11), but it's flat calm. If you’re desperate for a longboard or a SUP, you could get a few tiny, clean bumps. That's the highlight, if you can call it that.
The pattern continues: tiny, short-period swells, with the occasional clean moment. Wednesday morning, 12 August, sees a 1.0ft east swell with a light offshore wind from the southwest, making it clean (wave energy of 8). It’s the same story on Thursday, 13 August, with a morning offshore from the northwest and tiny 0.7ft east swell. The water temperature is about average for this time of year, so no surprises there.
Beyond that, it's a long, flat grind. The swell never gets above 2ft for the rest of the forecast, and the period rarely climbs above 9 seconds. The combined energy stays in the low two-digit range, meaning it’s all weak. For a spot that's consistent, this is a real dry spell. The only other standouts are a few glassy mornings: Tuesday, 18 August, with a 1.0ft east swell and pure glass, and Friday, 21 August, with another glassy morning and a 1.0ft east swell. These are your best bets, but honestly, it’s a session for the log or a flat-water paddle.
Given the persistent small swell, onshore winds, and the beach/jetty setup, this stretch looks more interesting for kite surfing than paddle surfing. It’s not often you see a blank run like this at the Inlet, but here we are. The forecasts can change, so keep an eye on it, but don't hold your breath.
Rusty.
