The Lowdown
Alright, Rusty here. Let’s talk about 120th Street. Honestly, it’s a total dry spell. From Friday the 14th of August all the way through the 29th, there’s nothing worth paddling for. The surf is flat or junk for the full 16 days – a real bummer.
The first few days are a waste. Friday the 14th is glassy but with only 0.3ft of swell and a combined energy of 6 – that’s flat. Saturday the 15th shows a little more wind but the swell is still tiny, and it’s cross-onshore and choppy. Sunday the 16th is a mess with heavy rain and a fresh cross-onshore breeze. Monday the 17th has a clean window with a light cross-offshore wind, but the swell is only 2ft at a short 6 seconds – weak, not worth it.
The only flicker of life is Tuesday afternoon the 18th. There’s a 2ft groundswell from the SE with a 12-second period, and the energy hits 90. The wind goes glassy, so it’s clean. But the waves are ordinary – just knee-high slop. If you’ve got a longboard and low expectations, you might get a couple of rides.
The rest of the second week is more of the same. Wednesday the 19th gets blown out. Thursday the 20th morning has a clean 3ft swell from the S at 5 seconds, but the energy is only 59 – weak and short-period. By the afternoon it’s dead calm and glassy, but only 2ft. Friday the 21st through the end of the month stays small, with most days showing swell under 3ft, short periods, and low energy. The water is 79°, which is a touch warmer than normal for this time of year.
Bottom line: leave the board at home. The only moment of glass is on the 18th afternoon, but it’s not enough to get excited about. Forecasts can change, but right now, there’s no real surf here.
Rusty.

Information about the 120th Street Surf forecast
The above surf forecast table for 120th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 120th Street can be found by selecting the local surf guide option on the grey menu. Our 120th Street surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
