The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our stretch of coast. We’re looking at a pretty flat and funky run ahead, so don’t get too excited just yet.
The first real sniff of anything worth paddling out for isn’t until the very end of the first week, but honestly, it’s a long wait for small stuff. We kick off Friday the 28th morning with tiny 1ft from the east at 9 seconds, winds are light offshore from the SSW, so the water is clean. The energy is weak, only 47, and it’s surfable but very ordinary. The water temp is about average for the time of year. After that, we hit a proper dry spell. From Friday afternoon all the way through to the morning of Monday the 7th of September, it’s a total write-off. Day after day of poor conditions, small weak swell, and onshore or cross-onshore breezes churning it up. Not worth your time.
Now, Monday the 7th of September morning finally brings a little hope. We’ve got 1ft of NE groundswell with a very long period of 13 seconds and clean conditions thanks to a light cross-offshore from the WSW. The energy is only 50 though, so it’s weak, but it’s at least surfable. This longer period stuff will be lining up best at the inlet and reef setups. Tuesday the 8th morning sees a bump to 3ft from the ENE with a 12-second period, and it’s clean again with light WSW cross-offshore wind. Energy is moderate at 177. This is probably the best on offer across the whole outlook — clean, punchy little walls at Sebastian Inlet-Third Peak.
Wednesday the 9th and Thursday the 10th mornings are similar, with 3ft from the ENE and clean cross-offshore winds. But here’s the real standout: Thursday the 10th afternoon. The swell holds at 3ft from the ENE, period drops to 10 seconds, but the wind goes glassy from the SSE and the energy jumps to 214 (moderate). That’s the pick of the whole forecast — a true moment of glassy goodness. It won’t be big, but it’ll be clean and fun on the bank.
The rest of the second week is more of the same small stuff, clean in the mornings but chopping up in the afternoons. Crowds are often around here, so don’t expect much company on those clean windows.
Rusty out.
