The Lowdown
Right, let’s have a look at what’s coming up at 120th Street. It’s a bit of a quiet start, I’m not gonna lie. The first real shot at something decent doesn’t show up until Wednesday the 23rd of September. Before that, it’s pretty much all poor surf conditions with small, weak swell and messy wind. There’s a solid stretch of nothing worth paddling out for from now right through until the morning of the 23rd – that’s over a week of flat to tiny, choppy stuff. The water temperature is sitting at 75°, which is a solid 4° warmer than usual for this time of year, so it’s notably warm.
The first whisper of hope is Wednesday morning, the 23rd. We’ve got a clean, glassy morning with 4ft of swell out of the east. It’s just about surfable, but very ordinary conditions. The combined energy is weak at best (160). The wind goes glassy, which is a serious bonus, but the swell is small and short-period at 7 seconds, so you’re not getting much push.
Now, hold on. The best on offer in this whole window is Wednesday afternoon, the 30th of September. That’s over a week away, so consider it promising but a bit uncertain. But here’s what the numbers say: 7ft of easterly swell with a 7-second period and light, clean cross-offshore winds. The combined energy jumps to 384 (moderate), and the comment says “expect good surf conditions.” For a beach/jetty setup like this, that’s the standout. The east swell matches up with the optimum direction for the spot, and that wind will keep it clean. It’s a bit much for beginners at over 5ft, but good for the average surfer.
The following morning, Thursday the 1st of October, shows a big pulse of energy – 1221 combined – with 8ft of swell, but the wind is a fresh cross-onshore from the north-northeast at 19 mph, which will ruin it. That one is for experts only on the size and blown out anyway.
So the call: Wednesday the 30th of September afternoon is your window. 7ft east swell, clean, cross-off breeze at 120th Street. It’s the only real standout in a pretty drawn-out period. Before that, just wait and watch.
