The Lowdown
G'day, I'm Rusty, and I've got the full rundown on what's in store for the next couple of weeks at Sebastian Inlet-Third Peak (Florida). Honestly, I'm calling it like I see it – this stretch is looking flat and pretty lifeless for the vast majority of the forecast. Swell energy is barely registering, with most values sitting below 100, which is about as weak as it gets. The water temp is sitting at a warm 85°F, which is right on the money for this time of year, so no surprises there.
We're looking at a long dry spell right from the start. The first solid week is a write-off for anything decent. The swell is tiny, never getting above 2 ft, and the period is mostly short and weak. Wind is almost always onshore or cross-shore, which just adds chop to the already flat conditions. Honestly, there's nothing to get excited about until we hit that second week.
Now, around the 7th and 8th of September, we start to see a slight shift. The swell picks up a little bit, but it's still nothing to write home about. We're looking at waves around 2 ft to 2 ft coming from the ENE, with a period of 10 seconds. The energy is still weak, with readings around 54 to 76. The real positive here is the wind. We get some clean conditions with offshore or cross-offshore breezes from the SW and SSE, which is a big deal for this spot. It'll be clean, but the waves are just "surfable" at best – not exactly pumping.
The best chance of a wave comes on the 9th of September. We've got a consistent 2 ft swell from the ENE, with a period of 11 seconds, and the combined energy finally cracks into the triple digits at 111! That's still weak energy, but it's the best we've seen. The wind is light offshore from the SW, glassing it up for the morning. It'll be clean, but the swell is still pretty small, so it's a board-choosing day. This is a rare opportunity for a surf, but it's a long way out, so treat it as promising but not a certainty.
Bottom line: This is a slow period. Don't get your hopes up for any standout sessions. The peak of the action is likely a mid-September morning with clean lines and a little bit of energy. Signing off, Rusty.
