The Lowdown
Alright, I’m looking at the forecast for 48th Street, and honestly, folks, it’s a tough one to sugarcoat. We’ve got a full 16 days on the books, but the surf is pretty much flatlined for most of it. The water is running at 79°, which is a solid 4° warmer than usual for this time of year – that’s much warmer than normal, and you’ll feel it for sure.
The first real chance to even get the board wet doesn’t roll around until Friday, August 28th, and even then it’s just a little 2ft swell from the southeast, with a short period of 9 seconds. The combined energy is a weak 67, so there’s not much oomph behind it. The morning is glassy, which is a bonus for clean faces, but it’s still just ordinary conditions. After that, it’s back to a long stretch of nothing until Wednesday, September 2nd, when we get a couple of afternoons with 2ft, 10-second period swells from the southeast, and the wind finally goes offshore from the west-northwest, cleaning things up. The energy is still only moderate at 56, so it’s more about a peaceful paddle than any real punch.
The standout here is the late afternoon of Wednesday, September 2nd. Swell is 2ft from the southeast, with a 10-second period, and we’ve got a gentle offshore wind. It’s the cleanest, most surfable window in the whole outlook, but you’ll want to keep your expectations low – it’s still just ordinary waves. No standouts in the second week, it’s just more of the same small, weak energy.
Honestly, for a beach and jetty setup like this, with the tiny swell and the long spells of onshore or cross-shore wind, it’s looking more interesting for a kite session than a proper surf. Keep your eyes on the forecasts, though – this area tends to pick up.
