The Lowdown
Alright, this is Rusty, and I gotta be straight with you – we’ve got a long, dry spell ahead for 47th Street. The next two weeks are looking pretty flat and uninspiring. For the first ten days, you’re looking at tiny, weak swells—mostly under 3 feet—with combined wave energy barely cracking double digits (12 to 74). The water is sitting at 77°, which is a touch warmer than normal for this time of year, but that’s about the only thing out of the ordinary around here.
We’re looking at a big gap right from the start. Thursday, August 20th through Sunday, August 30th? Nothing worth paddling out for. The swell is small, the period is short, and the wind is all over the place. A few morning windows might look clean, like Sunday the 23rd or Monday the 24th with a light offshore breeze, but with waves only 0.7 to 1 foot, you’re better off staying on the beach. The best call in that stretch is probably Sunday the 23rd afternoon—a light offshore wind from WSW, glassy, but the swell is barely a ripple.
Things get a little more interesting on Thursday, September 4th. The swell picks up to 7 feet from the east, with a period of 8 seconds, and the combined energy jumps to 572 in the morning and 623 in the afternoon. That’s a moderate to strong energy. But the wind is onshore all day from the east, making it messy. The wave comment says “marginal surf forecast” and rates it a 1/10. This is a big swell for the area, but with onshore wind, short period, and a beach/jetty setup, it’s more likely to be a choppy, blown-out mess. For the experienced crew only—this is not beginner territory.
Honestly, the only standout is that Thursday the 4th, but it’s a gamble. If you’re an expert and you’re desperate, you might find something, but the wind is working against you. For everyone else, it’s a waiting game. The break is fairly consistent, so it won’t stay this poor forever, but this 16-day window is a write-off.
Keep your eyes on the forecasts, but don’t hold your breath.
Rusty.
