The Lowdown
Alright folks, let’s get real about this 16-day window for Montauk. It starts off brutal—a full 5-day dead spell from Wednesday the 12th through Sunday the 16th. No swell, bad wind, nothing doing. Don't even bother waxing up.
The first breath of life is on Monday morning, August 17th. We get a clean NW offshore breeze and a small 4ft swell out of the SSW. Energy is weak, only 98, but it’s something. You might snag a few weak ones at Montauk Point – Turtles. It’s a reef, so you need to be an intermediate to make anything of it.
After another quiet stretch, Friday morning, August 21st delivers the first real pulse. A strong NW offshore wind cleans up a 6ft SSW swell. The energy reads 284 – that’s moderate power. The period is short though (7 seconds), so expect lumpy, close-interval sets. Afternoon stays clean offshore at 5ft. Water temp is average for the time of year at 71°.
Now, the one that has me talking to myself. It’s a long way out, but Wednesday morning, August 26th looks like the real deal. You get a glassy cross-offshore breeze from the NNE and a solid 6ft swell from the ESE. The combined energy hits 439 – that’s proper power. The period is still only 8 seconds, so it’s not a classic groundswell, but for Montauk in late August, that’s as good as it gets. It’s too big for beginners, but for experienced surfers, this is your session. Get on it early, because by the afternoon a lousy onshore wind kills it.
To wrap it up: the 21st is a decent fallback, but the 26th is the one to shoot for. Turtles can get crowded, so be ready for company. This is a lean spell, but there’s a couple of windows if you’re patient.
