The Lowdown
Alright, this is Rusty. Let’s talk about what’s happening at Sebastian Inlet-Third Peak.
Right up front, I gotta be honest with you – it’s a tough stretch ahead. We’re looking at a long, quiet run with very little to get excited about. The swell is tiny for days, and the wind is rarely doing us any favours. There aren’t any standouts to point to; the whole 16-day window is basically a write-off for a proper session.
Starting from Sunday the 30th of August, we’ve got small 2ft east swell with a short period of 6 seconds and weak wave energy (40-57). The wind is onshore or cross-onshore, and conditions are just poor. That sets the tone. Monday the 31st is more of the same, still 2ft east swell, period bumping to 8 seconds with moderate energy (128) on Monday afternoon, but it’s onshore at 16 mph – not good.
Tuesday the 1st of September through the weekend of the 5th-6th is an absolute drought. Swell heights drop to 0.7ft to 1ft, periods short, energy is weak (mostly under 100). Winds are mixed, but the waves are just too small to bother. You’ll see a couple of glassy moments Saturday afternoon the 5th and again on Wednesday morning the 9th, but those are still on 1ft to 2ft swell – barely a ripple. The water temp is about average for this time of year, nothing unusual.
The only flicker of life comes on Sunday the 13th of September. The swell direction swings to NNE then NE, height bumps to 4ft by the afternoon, but the period stays a short 6 seconds. Combined energy is still weak at 81. The wind is cross-onshore and choppy, so even with that slight increase in size, the quality isn’t there. It’s still a poor outlook.
Honestly, there’s no day I’d tell you to clear your schedule. Conditions never line up with even a modest swell. The combination of small waves and persistent onshore or cross-shore wind means we’re in for a blank run. For this area, that kind of quiet spell can happen, so it’s not a shock, but it’s a bummer. The setup looks more interesting for a kite surfer than a paddle surfer on the days with a bit of breeze.
Keep an eye on the long-range; forecasts can shift, but right now, it’s a long wait.
Rusty.
