The Lowdown
Well, folks, Rusty here, and I gotta be straight with you—this stretch of the forecast is a tough one to read. The entire 16-day window from August 21st through September 5th is a complete dud for surf at Montauk Point - Turtles (Montauk). We’ve got a solid two and a half weeks with zero standout sessions, so let’s just call it a period of watch and wait.
The pattern is pretty grim from the get-go. We kick off on Friday August 21st with a small NE swell around 4 ft, but it’s short-period windswell of just 5 seconds, and the combined energy is weak (101). Add a fresh 35 km/h cross-offshore wind from the NNE, and the water temp is about average for the time of year, but the surf quality is just poor. That theme sticks around through the weekend and into the start of the following week.
By Saturday August 22nd, the swell drops to 3 ft, energy falls to 66, and we’re stuck with a moderate cross-shore breeze. Sunday the 23rd offers a slight shift with a 4 ft swell from the S and a light cross-offshore wind, but the period is still only 5 seconds and the energy is weak at 90. Monday August 24th sees a bit of a bump with a 3 ft S swell and a 7-second period, clean conditions with a W cross-offshore breeze, but the energy is still only moderate (113). Still, the surf quality is listed as poor across the board.
The entire first week is a washout, with Tuesday the 25th dropping to 2 ft, and by Wednesday the 26th we bottom out at 1.0 ft with glassy conditions but almost no energy (28). That glassy morning is a tease, but there’s nothing to ride. The pattern continues through the end of August with tiny swells, onshore or cross-shore winds, and low energy readings—most days under 100.
The only glimmer comes on September 1st, when the combined energy jumps to 334 (moderate) and we see a 5 ft swell from the SW with a 6-second period. But the wind is a moderate cross-shore from the SW, and the surf is still poor. Then on September 2nd, we have a clean morning with a 4 ft SSW swell and cross-offshore winds from the N, but the energy is only 188 and the period is a short 6 seconds. Again, the quality is poor.
Even the final days, like September 4th with a 6 ft S swell and moderate energy (266), are blown out by cross-onshore winds. The swell is getting too big for beginners (over 5 ft), but the wind is ruining any chance of decent shape.
Honestly, folks, this is a blank run. The area tends to see these stretches where nothing lines up, and consistency is just not there. But don’t lose hope—forecasts can change, and it’s not often this poor for this long. Keep an eye on the horizon, but for now, the board stays in the car.
Rusty.
