The Lowdown
Alright, listen up. Rusty here, and I gotta be straight with you. Looking at the next 16 days for 120th Street, it's a pretty grim stretch. We've got a long, long dry spell ahead. The first real glimmer of anything surfable doesn't show up until over a week away, on Wednesday, the 9th of September. Before that, it's pretty much a write-off with tiny, gutless swell and dodgy winds.
The water temp is sitting at 77°, which is a touch warmer than normal for this time of year, so at least you won't be freezing while you're staring at flatness.
From the 29th of August all the way through to the 8th of September, it's a near-total blank. The swell is tiny, mostly 1.0 ft to 2 ft, with a weak combined energy that rarely breaks 100 (mostly in the teens to 90s). The wind is all over the place, mostly cross, onshore, or just messy. The models are calling it "poor surf conditions" every day, and I'm not gonna argue with that. There's nothing to get excited about.
Then, on Wednesday the 9th of September, we get a bit of a pulse. It's not a world-beater, but it's the best we've got. The morning shows a bump in swell to 3 ft from the SE, with a period stretching out to 12 seconds. That longer period means there's a bit more shape and energy behind it, and the combined energy jumps to 223 (moderate energy). The wind is clean, blowing cross-offshore from the SW. This is what we call "surfable but ordinary." It's a far cry from epic, but if you're jonesing for a paddle, this is your window. The afternoon looks similar, with the swell holding at 3 ft, though the period drops a touch to 11 seconds, and the energy is 153.
The next morning, Thursday the 10th of September, has the swell dropping back to 2 ft, but the wind is clean offshore from the W. It's weak, but it'll be clean. By Friday the 11th, the wind is howling offshore from the WNW at 22 mph, which would make for good conditions for a kite, but the swell is back down to 1 ft, so not much for a paddle surfer.
So, the standout is the morning of Wednesday, the 9th of September. That's the only time in the whole two weeks where the swell is over knee-high, has some decent period, and the wind is cooperating. It's a long way off, so don't hold your breath, but it's your only shot.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for 120th Street may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
