The Lowdown
G'day, Rusty here. Look, I've got to be straight with you—this outlook for the next 16 days is a bit of a bummer for Sebastian Inlet-Third Peak. We're staring down a long stretch of tiny, weak swell and crummy conditions, so don't get your hopes up for any decent waves.
The forecast kicks off with a few scraps of hope on the morning of Tuesday, August 4th, but it's a false start. The swell is a measly 1 ft from the east, with a short period of 8 seconds, and the combined energy is a paltry 18—barely a ripple. The water temp is about average for this time of year, so no surprises there. The morning's a bit clean with a light SSW breeze, but the waves are just too small to do anything with. The afternoon goes glassy with a WNW wind, but it's still 1 ft of east swell; it's pretty but flat.
We then hit a long, dry spell. From Wednesday, August 5th, right through to Saturday, August 16th, it's a mix of onshore winds, choppy conditions, and tiny swell. The waves never get above 4 ft, and even then, the period is short (5-8 seconds) and the wind is mostly cross-onshore, trashing any chance of a clean face. The combined energy peaks at 301 on Friday, August 7th afternoon, but it's still a messy, weak 4 ft east swell with a cross-onshore ESE breeze—just poor surf.
Finally, there's a glimmer on Sunday morning, August 16th. The swell is still only 2 ft from the ESE, but the period stretches to 8 seconds, and the combined energy climbs to 74. More importantly, the wind swings light and cross-offshore from the SSE, giving us clean conditions. The guidance says this spot is a consistent, intermediate-level beach/jetty break that's exposed to swell and prefers it from the NE, so this ESE swell is a bit off-angle. The waves will be surfable but very ordinary—small, weak, and only worth a paddle if you're desperate. That's the only window in the whole 16 days, and it's a marginal one.
After that, we're back to tiny 1 ft waves and clean but flat conditions through to Wednesday, August 19th. It's a blank run, plain and simple. If you're a kiter, the onshore breezes from the east might get you out on the water, but for a surfer, this is a hard pass. Hang tight, the forecasts can always change, but right now, it's a quiet stretch.
Rusty.
