The Lowdown
Grab your board, but maybe leave the quiver at home this stretch. We're looking at a classic late-summer lull for 47th Street. For the next week and a half, it's basically flat and frustrating. We're talking days on end where the wave heights are struggling to hit 3ft, and most of that is short-period windswell, not anything with real push. The swell energy is weak, hanging in the low double digits and teens for most of that time, like 10 to 40, barely a pulse. It's a tough stretch for the regulars. Don't get me wrong, the water is warm at 78°, about 3° above normal for this time of year, which is a touch warmer than we're used to, but it's not making up for the lack of surf.
We're going to see a few glassy mornings and some offshore winds, like on Thursday the 20th, where the wind is offshore and clean, but the swell is just too tiny to make it worth paddling out. It's the kind of day you'd sit on the beach with a coffee, not the one you call in sick for. The weekend of the 16th and 17th is looking particularly meh, with the swell dropping out entirely. This is a blank run, plain and simple.
Now, there is a tiny light at the end of the tunnel. It's not until Sunday the 23rd, and even that is only a "surfable but very ordinary" kind of day. We're only looking at 3ft from the ENE with a 6-second period, light offshore wind in the morning. It's the first day in a long time the energy gets into triple digits, with a reading of 81. It's not a standout, it's just the first day that's not a complete zero. You’ll get a few sloppy ones in the morning, but it’s not going to be a classic.
Then there's another lull, and the most promising window is the start of the second week, around Friday the 28th. The swell energy finally starts to show some moderate muscle, hitting 102-105. We're still looking at sub-2ft surf, around 2ft, but it’s from the SE with an 11-second period, which is a bit more of a groundswell. That's better shape potential, but it’s still small, and the offshore wind is only moderate cross-off. It’s a step in the right direction. It’s just a shame it’s not bigger. This is a long-range call, so I wouldn’t get too excited yet, but if I had to pick a day to keep an eye on, it’s that Friday. Everything else is a waiting game, and for a beach/jetty setup like this, the longer-period swells can get a bit straight, so let’s hope for a bit of angle. It's not much, but it's all we got.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for 47th Street may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
