The Lowdown
Alright, Rusty here, switching to the old-school numbers. Let’s look at what’s happening at 47th Street. I ain’t gonna sugarcoat it – it’s a grim outlook for the next couple of weeks.
The water’s running about 78°F, and that’s a good 5°F warmer than normal for this time of year. Feels like you’re taking a bath.
From right now, starting Friday the 21st, it’s poor. Tiny, weak swell with a combined energy of just 13 to 30 – that’s nothing. The wind is a mess. Saturday the 22nd is more of the same. Then we hit a long, flat stretch. From Sunday the 23rd of August all the way through to the beginning of September, the swell barely moves. You’re looking at ankle-high bumps, mostly 1.0 to 2 feet. The wave energy stays in the teens and twenties. The wind sometimes turns clean or offshore – like on the 24th and 26th of August – but with waves that small, it’s barely a ripple. It’s a long, boring run until the tail end of the forecast.
The only tiny flicker of hope comes on Saturday the 5th of September. You get glassy conditions, no wind, and a 2-foot bump from the south. But the period is only 4 seconds, which is real short and crumbly. The energy is still weak, just 20-21. For a proper stick, it’s terrible. For a longboard or a soft-top, you might manage to nose-ride a few knee-high sliders if the swell lines manage to hold together.
So, to wrap it up: there’s nothing good on offer in this entire 16-day window. No standouts. The wave energy never even hits triple digits. If you have to get wet, the best you can do is the very last day – September 5th – for some clean, tiny, soft bumps. But otherwise, this is a flat spell that just keeps on giving nothing. Don’t get your hopes up.
Rusty.
