The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next stretch at Sebastian Inlet-Third Peak (beach/jetty). Straight up, it’s a quiet run. The ocean isn’t giving us much to work with.
We’ve got a long dry spell to start. From Tuesday afternoon the 25th of August all the way through to the morning of Friday the 28th of August, it’s pretty much flat or tiny, and the conditions are messy – thunderstorms, cross-breezes. Not worth paddling out for. The water temp is sitting at 85°, which is about normal for this time of year, so no surprises there.
Friday the 28th of August morning shows a tiny bump of 1ft from the East, with a clean cross-off breeze from the SSE. It’s surfable, but the energy is weak, around 47. It’s ordinary but it’s the first real chance to get wet. There’s a bit of consistency in the break, but the swell is barely there. You might get a slide on a longboard.
After that morning, it drops right back into the weeds. The rest of the run through to the end of the first week of September is a mix of tiny swells, cross-onshore winds, and frequent risk of thunderstorms. Nothing offering any shape or push. Most mornings have a light breeze but the swell is so small it’s barely a ripple.
Looking ahead to Thursday the 3rd of September morning, there’s a slight lift. A 2ft swell from the East, period of 10 seconds, and a clean cross-off breeze from the SSE. Energy climbs to 90 – still slight, but the best it’s been. The wind will clean it up nicely. For the area, this is the standout window. It’s not big, but it’s rideable and tidy.
However, the afternoon on that same day turns cross-shore with a slight chop, and the following days are back into the same mediocre pattern. From Friday the 4th of September onward, the swell stays small, winds are onshore or cross-onshore, and the energy drops away again. The final few days up to Wednesday the 9th of September are the weakest of the run – tiny swells, onshore flow, barely 17 to 28 combined energy.
Truth is, nothing in this 16-day window gets me excited. The break is consistent, but the ocean isn’t delivering. It tends not to stay this flat forever, so forecasts might change, but right now, we’re looking at long gaps with very little to grab. If you’re desperate, Thursday the 3rd of September early is your best bet – otherwise, I’d keep the board in the car and wait.
Rusty.
