The Lowdown
Alright, let’s get into it. The next couple of days are pretty flat, but that doesn’t mean there’s nothing to look forward to. We’ve got a bit of a wait on our hands, but the back half of the run starts to show some real potential.
Right now, Tuesday (August 25th) and Wednesday (August 26th) are going to be a write-off. We’re looking at tiny, weak swells and messy winds. It’s not worth paddling out for. Honestly, you’re better off doing something else until Thursday.
Thursday morning (August 27th) shows a small pulse of 3ft from the northwest with a 7-second period. The energy is still pretty weak (73), and while the wind is light and cross-offshore, the waves are just too small and crumbly to get excited about. The afternoon drops off even more. It’s a frustrating start, but hang in there.
Friday (August 28th) is where things start to wake up. The swell bumps up to 5ft in the morning, also from the northwest, and the period stretches to 8 seconds. The energy is now moderate (250), and with a light offshore breeze, it’s going to be a lot cleaner. It’s not huge, but it’s definitely surfable. The afternoon cleans up further with the swell pushing 5ft and a 9-second period, and the energy is solid now (402). The wind is cross-offshore, so it should shape up nicely. This is your first real session.
Saturday (August 29th) morning looks magic. The swell settles a touch to 4ft, but the period is a clean 9 seconds, and the wind is dead glassy. The energy is still solid (249). This is going to be the pick of the early window. Clean, chest-high waves with nobody around is a good bet. The afternoon gets a bit more onshore, so make the most of the morning.
Sunday (August 30th) is another good one, especially in the afternoon. The morning has a smaller 4ft swell with a glassy start. But the afternoon brings a 4ft swell with a 12-second period and clean conditions. That’s a jump in quality there. The energy is strong (328), and those longer-period waves will have more push. This is where it starts to get fun.
Monday (August 31st) is a bit of a mixed bag. The swell is holding at 4ft from the northwest, but the wind is stronger and more cross-offshore. It’s clean but a bit bumpy. Surfable, but not the best day.
Tuesday (September 1st) morning is going to be a real standout. The swell is 4ft, but the wind is completely calm – dead glass. The energy is moderate (241), and those sets will be rolling in perfect. This is the one to circle. The afternoon drops off with onshore wind, so it’s a morning-only deal.
Wednesday (September 2nd) is a no-go. The swell actually builds to 5ft, but the onshore wind is strong and will just make it messy. The energy is strong (582), but it’s going to be a blown-out mess. Not worth it.
Thursday (September 3rd) gets better again. The morning has a clean 4ft swell with a moderate offshore wind. The afternoon is smaller, a touch over 3ft, but still clean. It’s a fun, small-wave day.
We then hit a bit of a lull from Friday (September 4th) through Saturday morning (September 5th). The swell fades to next to nothing. It’s a flat spell, so give it a rest.
But don’t worry, the long-range looks promising. By Sunday (September 6th), the swell kicks back up again. The morning has 4ft with a moderate offshore wind, but the afternoon is the winner. It jumps to 5ft, and the period goes to 10 seconds, and the wind is light and clean. That’s another quality session.
Monday (September 7th) holds that 5ft swell for the morning, but the wind gets stronger and a bit messy. The afternoon cleanup is less certain.
The week after that is a slow fade. The swell stays around the 3ft mark, but the periods are good, and the wind is mostly light. The morning of Wednesday (September 9th) looks like a nice, clean, small-day option.
So, looking at the whole 16 days, the two absolute standouts are Saturday morning (August 29th) with that glassy 4ft and Tuesday morning (September 1st) with the dead-calm 4ft. They’re your best bets for clean, fun surf. The Sunday afternoon (August 30th) and Sunday afternoon (September 6th) are also strong contenders. Just remember that the further out we go, the less certain the forecast is, but it’s looking promising.
The water’s a touch warmer than usual for this time of year, so it’s comfortable out there. Keep an eye on the forecast; a run like this doesn’t stay flat for long.
Stay stoked.
