Table - best surf conditions forecast for Sebastian Inlet-Third Peak over the next 16 days.
Alright, this is Rusty. Let’s be straight with you – the outlook for Sebastian Inlet-Third Peak over the next 16 days is pretty grim. We’ve got a long, flat gap staring at us. Honestly, there’s nothing worth paddling out for on the horizon.
Looking at the data, the first record we get is for Sunday the 12th of July, and it’s showing a tiny 1ft easterly swell with a short period of 8 seconds, on a cross-onshore breeze. Combined wave energy is weak at just 17, so that’s a no-go. That sets the tone for the whole run.
We then move through Monday the 13th and Tuesday the 14th, and it’s the same story – ankle-snappers at best. A few mornings show some clean, offshore wind from the SSW, but with the swell dropping to less than 1ft and energy readings in the single digits (5 to 12), there’s just nothing to ride. Wednesday the 15th through the weekend barely tickles 1ft out of the NE, with periods hardly hitting 7 seconds. It’s weak, choppy, and not worth your time.
The second week doesn’t offer any hope either. From the 20th of July onward, we’re stuck in a pattern of tiny less than 1ft to 1ft swells, with periods lingering below 8 seconds. Even when we get a clean offshore wind on the morning of the 21st, the swell is only 1ft – barely a ripple. The combined energy for any given session rarely breaks past 24, which is telling you it’s flat.
The standout here really is the lack of any standout. This is a classic summer flat spell for the area. For a break that needs a decent NE swell to get going, this 16-day window is a bust. If you’re itching for something, the clean mornings with offshore wind might give you a tiny, clean wave on a longboard, but honestly, you’d be better off waiting for a proper swell.
Hang tight, the forecasts can change.
Rusty.
