The Lowdown
Alright, this is Rusty. Let’s talk about the surf coming up at 120th Street. It’s a beach/jetty setup, fully exposed to the swell, and the water temp is running about average for this time of year.
Right now, we are sitting in a flat spell. For the first several days, from Wednesday morning all the way through to the end of the first week, there is no surf worth paddling out for. The waves are tiny, mostly under 2ft, and the energy is weak – you’re looking at combined swell energy as low as 18 on Friday afternoon. The wind does go glassy on Friday afternoon, which is pretty, but there’s nothing to ride. This stretch is a total bust.
We hit a long gap with no recommendations until the 7th of September, which is Monday morning. On that day, there’s a small bump of 3ft from the ENE, with a 9-second period, glassy conditions, and combined energy of 119. It’s still weak, and the wave comment says “surfable but very ordinary.” This is the first time we can even call it surfable, but it’s not going to get your heart racing.
Moving into the second week, there’s more waiting. The 15th of September, Tuesday afternoon, brings 4ft from the NE with a short period of 5 seconds, and combined energy of 69. Offshore wind from the WNW will keep it clean, but the period is so short the waves will be weak and crumbly.
The standout in this whole 16-day window comes on the 16th of September, Wednesday morning. Swell builds to 4ft from the ENE, period around 7 seconds, combined energy jumps to 266 – that’s moderate-strong energy. Winds are light cross-offshore from the WNW, so the surface stays clean. This is the best we’ve got. It’s not huge, but it’s the only time the energy level really steps up and conditions line up. Expect clean, surfable waves with a bit of push. Keep in mind, with that shorter period, it’ll be a bit sectiony at the beach, but for this run, it’s the one to aim for. The following Thursday morning, 17th September, sees a bigger 6ft from the E, but the period is still short at 6 seconds, and combined energy is 247. Offshore wind keeps it clean, but at 6ft, it’s pushing into intermediate territory, and the short period will make it dumpy.
Overall, this is a two-week outlook with a whole lot of flat and only one real bright spot. The 16th and 17th of September mornings are the only times to even consider it, and the 16th is the pick.
Rusty.
