The Lowdown
Alright surfers, Rusty here. Let’s be straight with you—this forecast for 47th Street is a tough one. We’re looking at the full 16-day window and honestly, it’s a real flat spell for the most part. There’s a long stretch of days where you’d be better off doing anything else. The standouts are very few and far between.
Right from the start, Sunday the 16th, we’ve got tiny 1 ft swell coming from the SSE with a short period of 6 seconds. Wind is a cross-shore breeze at 12 mph, and the combined energy is weak at only 17. It’s just poor conditions all day. This sets the tone for the next week and a half.
You’re looking at a big gap here. From Sunday the 16th all the way through to Wednesday morning the 26th of August, it’s just a whole lot of nothing. Swell heights barely crack 2 ft, periods are mostly short, and the energy (reading between 2 and 41) is just not there for a proper surf. There are some clean moments, like Tuesday afternoon the 18th with light offshore winds, but the waves are a mere 0.3 ft. It’s not surfable.
Now, we finally see a flicker of life on Thursday the 27th of August. This is the only real standout on offer. We’ll see a 2 ft SE swell, with a decent period of 12 seconds. The winds are offshore from the WSW at 12 mph all day, which will keep the surface clean and lined up. The combined energy reaches 94, which is moderate. It’s not big, but it’s the best we’ve seen. The water temp is around 78°F, which is a touch warmer than normal for this time of year at 47th Street. This is a window for the patient surfer who just needs a few fun ones on the jetty.
After that little burst, it fades again. Friday the 28th through Monday the 31st sees the swell drop back to 2 ft-2 ft, with periods dropping and onshore winds returning. The energy spikes to 136 on the 30th, but that comes with a messy 9-second period and onshore wind, so it’s a bit of a waste.
Bottom line: this 16-day run has a massive flat spot. If you’re desperate, the morning of Thursday the 27th is your only real shot. For the rest, it’s a bust.
Rusty.
