The Lowdown

G'day, Rusty here. Well, truth be told, we’re looking at a pretty grim stretch for a surf at 120th Street. The whole 16-day window is a write-off, if I’m being honest. The wave energy is just too weak and the conditions are mostly messy. There’s nothing here that’s going to get you out of bed.

The first solid week is a total dud. We’re talking tiny, weak swell with combined energy figures barely cracking 30 or 40 (26, 22, 28, 34), and the water is a touch warmer than normal at 78°F on Monday morning. You’ll be sitting out there on a 2 ft wave from the SSE with a short 6-second period, which is just a bump. There’s a bit of a glassy moment on Monday afternoon, but the swell is only 2 ft, so it’s not surfable. A few mornings with a clean cross-offshore wind, but the swell is so small (1 ft to 2 ft) it’s not worth a mention.

Towards the end of August, the swell tries to pick up a bit, but the wind ruins it. By Tuesday the 25th, we get a 5 ft S swell with a short 6-second period, and the combined energy finally hits 138, but it’s coming with a fresh cross-onshore wind that chops it right up. That’s not surfable, it’s a mess. Then on the 28th, the energy jumps to 425, but it’s a 3 ft ESE swell with a 13-second period and a 22 mph NE cross-onshore wind. That’s more of a kite-surfing situation than a paddle session. The period is long, but the wind is too strong and the direction is wrong for this exposed beach/jetty. The break is consistent, but that doesn’t help when the wind is on it.

The last few days of the window bring a little more hope, but it’s still marginal. On Sunday the 30th, there’s a 4 ft E swell with an 8-second period and a gentle cross-shore wind. The combined energy is 238, which is moderate, but the wave comment says “marginal surf forecast or questionable tide conditions,” so I’d be cautious. The wind is cleaner on Monday the 31st with a cross-offshore breeze, but the swell drops back to 3 ft.

So, the honest truth is: there are no good surf options in this 16-day window. The swell is too small, the wind is too often onshore, and when the energy does appear, it’s blown out. For a break that’s generally consistent, this is a flat spell. It won’t last forever, but for now, leave the boards in the car.

Rusty.

Information about the 120th Street Surf forecast

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.
