The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards.
To be blunt, it's a tough stretch ahead for Sebastian Inlet-Third Peak. We're looking at a solid 16-day run, but the surf quality just isn't there. The water's a touch cooler than usual for this time of year, sitting at 81°, about two and a half degrees below average, so you'll feel that slight chill.
The whole period is plagued by small swell and mostly poor conditions. The first two weeks are dominated by tiny waves—waist-high at best, often smaller, with short-period, weak windswell. The combined swell energy is well under 100 for the entire first week, often sitting in the teens and twenties, which tells you there's just no grunt in the water.
The only real blip of interest is around Friday, August 7th, and into Saturday, August 8th. That's when we finally see a slight pulse of east swell, pushing wave heights up to around 3ft to 4ft. The period stretches to 8 seconds, and for a moment the combined energy bumps up to 106-144, so there's a little bit of life. But the wind is the killer here—it's going to be cross-onshore or onshore from the east, putting a chop on it. It's surfable, but it's not going to be clean. The better calls are likely the early mornings when the breeze is a touch lighter.
After that brief bump, it drops straight back down to tiny, weak surf for the second week. From August 10th onward, we're back to knee-to-waist-high dribble with messy cross-shore winds. That Saturday morning, August 15th, and Sunday morning, August 16th, offer a moment of glassy conditions, but the swell is so tiny (1ft to 2ft, with period down to 4 seconds) that you'll be doing more floating than surfing.
So, the standout period is really just that one window on Friday the 7th and Saturday the 8th, but don't get your hopes up for perfection. The rest of the run is a write-off for any decent paddle surfing. With the east winds, small swell, and beach setup, this stretch looks more suited to a kite than a longboard.
