The Lowdown

Alright, Rusty here. Let me give it to you straight for 120th Street. Looking at this whole 16-day window, it's a tough one. The swell is weak and the periods are short for most of it. On the 16th of August, we're looking at a combined energy of just 34, with a 1.0m swell from the SSE but only 4 seconds of period – total junk. The wind is a southerly at 19 mph, making it a lumpy cross-shore mess. Water temp is a touch warmer than normal at 79°, but that's hardly a consolation.

The only real window to bother with starts Monday the 17th. The morning has a light westerly offshore breeze at 9 mph, and the swell is small, 0.7m from the south, with a combined energy of 34 again. It's clean, but it's tiny. Monday afternoon gets even better: a glassy 0.5m from the SSE with the wind dropping to a light 3 mph out of the northeast. That's your best chance for a clean but very small longboard session.

Then, from the 19th all the way through the 26th of August, it's practically flat. Swell drops to 0.2m to 0.6m, the wind is generally onshore or cross-shore, and the combined energy is almost always below 50. There is no surf to recommend.

The only other flicker is on the 27th of August, Thursday afternoon. We finally see a combined energy of 125 – moderate, at least compared to the rest. It's a 0.5m swell from the SE with a longer period of 11 seconds, giving it a bit more punch. The wind is a light northerly at 6 mph, which is cross-offshore and clean. The report calls it "surfable waves but very ordinary conditions." This is the only time in the outlook that scores a 1 out of 10. It's not good, but it's the only time you might actually stand up.

After that, it's back to small, weak, and choppy through the end of the month. There's nothing over 1.5m anywhere, so it's never too big for anyone, but it's also rarely worth paddling out. Keep your board in the car, but don't get your hopes up. 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. If you surf the same spot (120th Street) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
