The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for 48th Street over the next couple of weeks.
Honestly, the 16-day window gets off to a slow start. For the first ten days, from Saturday the 12th right through to Monday the 21st, there’s really nothing worth paddling out for. We’ve got a long stretch of tiny, weak, and mostly messy conditions. The swell is small, the wind is often on it or cross-onshore, and the wave comment is just “poor surf conditions” day after day. It’s a frustrating run, but that’s how it goes sometimes.
Now, things start to shift around Tuesday the 22nd of September. The combined swell energy jumps to 595 (moderate energy) in the morning, with a 7ft swell coming from the ENE. But the wind is cross-shore, the conditions are lumpy, and it’s only rated as marginal. That afternoon, a near gale blows up from the southeast, so you can forget about it.
The real standout, and the only one worth getting excited about, is Wednesday the 23rd of September. That morning, 48th Street looks like it could be on. We’ve got a solid 8ft swell out of the ENE, with a period of 9 seconds, and the combined energy is pumping at 1060 (strong wave energy). The wind is offshore from the west-southwest at just 9 mph, which is going to groom it beautifully. The wave comment says it’s excellent for experienced surfers. This is a proper groundswell setup, and that size is pushing into expert territory, so it’s not for beginners. Wednesday afternoon stays clean but gets even bigger at 10ft with offshore winds, though that might be pushing the limits of the break.
Thursday the 24th still has size – 10ft from the east – but the wind swings cross-off and then fresh cross-shore, making it lumpy and harder to handle.
So, to keep it simple: if you’re an experienced surfer, circle Wednesday the 23rd of September on your calendar. That’s the one morning where it all comes together – clean offshore wind, solid groundswell, and serious energy. The rest of the window is mostly a write-off.
Stay patient, and keep an eye on the forecasts.
