The Lowdown
Alright, folks, Rusty here again. Let’s talk about 120th Street in the old units. I’m not gonna sugarcoat it – the next 16 days are a real bummer. There’s a huge gap with no surf worth mentioning. The whole forecast is a dry spell. Swell is tiny, periods are short, and the conditions are just plain poor. There’s a bit of a pulse in the second week, but it’s nothing to write home about. For a spot that’s usually consistent, this is a quiet stretch, but it happens. The water temp is 78°F, which is a touch warmer than normal for this time of year.
The closest thing to a wave comes around Monday, August 17th. We get a little bump from the south with swell heights around 3ft, but the period is only 6 seconds. That’s short-period windswell – weak and mushy. The wind is cross-shore from the north, and the energy is low at 89. Not enough to get me out of bed. Then on Tuesday, August 18th, the swell shifts to the southeast with a 15-second period – that’s a long-period groundswell – but the height is only 1ft. The wind is a cross-onshore northeasterly at 15 mph, and the energy climbs to 100. Still, it’s messy and tiny.
The best of a bad lot? It’s gotta be the morning of Wednesday, August 19th. The swell picks up to 2ft from the southeast with a 12-second period, and the energy is moderate at 154. But here’s the problem: the wind is blowing onshore from the east at 15 mph. It’s gonna be a choppy, blown-out mess. For a beach and jetty setup like this, it’s more of a kite-surfing day than a paddle-surfing day. The conditions just aren’t there for us.
So, what’s the verdict? No standout days. Nothing’s breaking clean. The water is warm, but that’s about it. If you’re really itching, keep an eye on that Wednesday the 19th, but don’t expect much. It’s a waiting game now. Forecasts can change, but right now, this is a blank run.
Rusty.

A general guide to surfing at 120th Street can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
