Cupsogue Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be straight with you – it’s a tough stretch ahead for Cupsogue. The long-range models are showing very little to get excited about, so we’re looking at a lean couple of weeks.

The problem is right from the start. Through the first week, we’ve got a persistent south-west to south wind blowing across the beach, and the swell is both tiny and weak. There’s a combined wave energy sitting mostly in the 20s, 40s, and low 100s (weak to barely moderate), but with heights struggling to hit 3ft and periods locked at 6 to 7 seconds, it’s messy, weak, and onshore. The water temp is around 73°, which is about normal for this time of year, but that’s the only thing that’s normal.

The only real standout in this entire 16-day window is a brief moment on the morning of Saturday, August 15th. The wind goes dead calm – glassy conditions – and the swell is 2ft from the south with a period of 5 seconds. The combined energy is only 16 (weak), but that glassy surface will make it look a hundred times better than it is. It’s not a wave to write home about, but if you’re desperate for a clean, tiny knee-slapper, that’s your window. It’s a beach/jetty setup, so with that super short period, expect it to be a bit lumpy and soft, but at least the wind won’t be ruining it.

After that, the patterns go back to the same old story: cross and cross-onshore winds, tiny swell, and plenty of chop. There’s a few days around the 18th and 19th of August where the wind clocks offshore from the north-northwest, and the swell period stretches to 9 seconds, but the height is only 1ft. The combined energy is still stuck in the 20s (weak). It’s surfable only if you’re on a log and have zero expectations – clean, but barely any push.

For the rest of the run, it’s a grind. The 20th of August brings a bit of a bump with a 2ft south-southwest swell, but it’s a short-period 4-second windswell, and the wind is cross-onshore. By the 21st, the wind is howling at 18 to 22 mph from the south-southwest, and the surf is just a messy, lumpy 3ft. That’s more of a kite-surfing scenario than a paddle-surfing one.

Bottom line: we’ve got one very marginal clean window on the morning of the 15th, and then a few clean but tiny days around the 18th and 19th. Don’t hold your breath for the rest. This is one of those spells where the forecast can change, but right now, it’s a whole lot of “meh.”

Rusty.
