The Lowdown
Alright, let’s talk surf, 47th Street style.
This whole 16-day window is a tough one. We’ve got a big dry spell right at the start, with nothing worth paddling for. The first real sign of life comes on the afternoon of Sunday, August 16th.
Water temp is about 78°, which is a touch warmer than normal for this time of year, so you’re fine in boardshorts or a spring suit.
From Monday the 10th through Saturday the 15th, it’s tiny. Swell heights are 0.3 ft to 1 ft, mostly from the SE, with weak periods often under 10 seconds. The combined energy is in the single digits (2–12). The wind is sometimes offshore or glassy, which would be perfect if there were any waves, but there just aren’t.
Sunday the 16th afternoon brings a bump to 4 ft from the S, with a short 5-second period. The combined energy is 71 (moderate). The wind is cross-off from the SSW at 19 mph, keeping it clean. But that short period at a beach/jetty means it’s going to be weak and a bit messy. It’s the best of a bad lot.
The real standout, if you can call it that, is Wednesday the 19th. The swell hits 2 ft to 3 ft from the SE, with a 12-second period—that’s a proper groundswell, which is a good sign. The combined energy is moderate (145–179). The wind is onshore or cross-onshore, so it’ll be a bit choppy. Still, that’s the best wave of the forecast.
Thursday the 20th and Friday the 21st see the swell drop to 2 ft with SE direction and periods of 9–10 seconds. The wind is cross-off, so it’s clean, but the energy is weak (63–101). That long period groundswell can break a bit straight at a beach break, so shape won’t be great.
The 22nd and 23rd are back to small 1 ft to 2 ft ESE swell with 8-second periods. The wind is cross-off or cross-on, but it’s just too small.
So, the only session that might get your heart rate up is the 3 ft, 12-second SE swell on Wednesday the 19th, ideally in the afternoon if the wind lays off. It’s not a classic, but it’s the best we’ve got.
Otherwise, it’s a flat spell. 47th Street is fairly consistent, so this kind of dry run is unusual. Don’t give up hope—forecasts can change. But for now, I’d keep the wax in the wrapper.
Rusty, out.
