The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
To be straight with you, it’s a pretty bleak stretch for Sebastian Inlet-Third Peak. The swell is tiny and inconsistent for the entire run, and we’ve got a long gap of nothing worth paddling out for. Things start off flat with rubbish conditions. The first few days are a write-off – tiny waves, cross-shore winds, just nothing to get excited about. From Saturday 22 August through to Tuesday morning 1 September, it’s all poor surf conditions with barely a ripple. That’s a solid ten days of flatness.
The first real glimmer shows up on Tuesday morning 1 September. We’ve got a weak 1.0ft to 2ft easterly swell, but the wind swings light offshore from the SSW, which cleans it right up. The combined energy is still weak at 63 (moderate energy), but the surf is surfable, just ordinary. The real standout of the whole window is that Tuesday afternoon, 1 September. The swell bumps up slightly to 2ft from the east, and the wind goes glassy from the SSE. Combined energy hits 90 (moderate energy). It’s not gonna be pumping, but it’ll be clean, small, and there’ll be a few fun ones for those who just need to get wet. The 8-second period means it’s windswell, so it’ll be a bit mushy, but for the size, you’ll get a wave.
Wednesday morning 2 September offers a half-decent option too: 2ft east swell with a longer 12-second period, light cross-off SSW wind, and clean conditions. The combined energy is 94 (moderate energy). Feels a bit more pushy, but still small.
After that, Thursday morning 3 September has a glassy start with 2ft east swell and a 10-second period, combined energy 109 (moderate wave energy). But the wind swings onshore by afternoon, so the window is narrow.
From the end of the first week into the second, it’s back to tiny, messy, and mostly cross-onshore winds. The second week is a dud, with nothing worth chasing.
So, if you’re keen, the best bet is that Tuesday afternoon 1 September. It’s the cleanest, glassiest, and most consistent window in a very flat period. The water temperature is sitting at 85°F with a near-normal anomaly, so it’s warm as bathwater, just like you’d expect for this time of year.
Rusty.
