The Lowdown

G'day, I'm Rusty. Let's have a look at what's on the menu for the next couple of weeks here at Sebastian Inlet-Third Peak. Straight up, I gotta be real with you – it's a flat spell, and a long one at that. We're looking at a solid stretch of tiny, weak surf with barely any energy in the water, and it's gonna be that way for days.

The pattern is clear: we're stuck in a run of small, short-period east swell, with heights barely pushing 1 ft to 2 ft. The combined energy is in the low double digits for most of the first week, like 21 (weak energy) on Wednesday morning, dropping to 12 (weak energy) by Friday morning. That's about as weak as it gets. The water temp is sitting at a warm 85°F with no anomaly, so it's just normal for this time of year – nothing special there.

The best we can hope for is a bit of glassy or offshore wind to make the most of the ankle-biters. Wednesday morning (19th August) has a light WNW cross-off breeze at 6 mph, keeping things clean, but the swell is only 1 ft at 9 seconds – not enough to get excited about. Thursday morning (20th August) sees a glassy 3 mph west wind and 1 ft swell, but again, it's just a glorified bathtub. Saturday morning (22nd August) has a clean 6 mph south-southwest offshore wind, and Sunday morning (23rd August) is similar with a light southwest offshore, but the swell is still 1 ft. It's frustrating.

There's a gap of poor conditions all the way through until the end of August. The first hint of anything surfable shows up on the morning of Sunday, 30th August, with a score of 1/10. That morning we get a glassy 3 mph southeast wind and 2 ft east swell at 9 seconds, with combined energy still low at 44 (weak energy). The comment says "surfable waves but very ordinary conditions," and I'd agree – it's a tiny ripple, but at least it's clean. Monday morning (31st August) sees a slight bump to 3 ft from the northeast, but it's onshore wind at 6 mph, and the period is a short 6 seconds, so it's junk.

The second week is more of the same. The best-looking window is the morning of Wednesday, 2nd September, with a glassy 3 mph north wind, 2 ft east swell, and a period of 11 seconds. That's a longer period, which gives a bit more shape, and the combined energy is 78 (still weak energy). It's not a stand-out, but it's the cleanest we'll see. Thursday morning, 3rd September, is also glassy with a calm wind and 2 ft east swell at 10 seconds – again, just barely surfable.

Honestly, there's no standout session here. The whole 16 days is a write-off for any decent waves. If you're desperate, the glassy mornings with 2 ft swell are the only option, but bring a longboard and low expectations. The setup is so weak and the period is short, it's more interesting for a paddle on a SUP than a proper surf. Keep an eye on the forecasts, though – it rarely stays this flat for long.
