The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming up.

To be straight with you, the next week and a half is a bit of a write-off at 120th Street. We’re looking at tiny, weak swells, mostly under 2 ft, with a lot of cross-shore or onshore winds messing up the surface. The energy is really low, with combined swell energy values barely scratching double digits (10 to 26). It’s the kind of stretch where you’d be better off doing something else. The water temp is sitting at 78°, which is a touch warmer than normal for this time of year, so at least the water’s nice.

There’s a long gap of pretty much nothing until we hit Monday, August 17th. That morning, things finally get interesting. We’ve got a clean, offshore wind from the WNW at 9 mph, and a solid 5 ft SSW swell pushing in. The combined energy jumps to 257 (moderate), which is a big step up. The wind is offshore, so the waves should be clean and well-shaped. This is a proper window for the intermediate surfer, though it’s not overly big. The swell direction from the SSW is a good match for the spot’s optimum SE direction, so expect some decent lines. The wind stays cross-off that afternoon, but the swell drops back to 2 ft, and the energy backs off to 44 – so the morning is the clear standout.

After that, it’s back to small stuff and poor conditions for the rest of the 16-day run. A few days see periods over 11 seconds, like the 18th and 19th, but the swell heights are tiny (0.7 ft to 2 ft) and the wind is messy. The 21st of August morning has glassy conditions with a 1 ft SE swell, but honestly, it’s just not enough to get excited about. The 23rd of August morning offers a 3 ft S swell with clean cross-off wind, but the energy is still low (78) and the surf is described as ordinary.

So, the only real standout is Monday morning, August 17th. That’s the one to circle. The rest? You’re waiting.

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.
