The Lowdown
Alright folks, it’s Rusty here, and I’ve gotta be straight with you – the next couple of weeks for Southerndown are looking pretty grim. We’re staring down a long, flat spell with hardly anything worth paddling out for. The only real whisper of life doesn’t show up until the end of the run, but even that’s a gamble.
We kick off on Tuesday the 8th of September with a bit of swell in the water, about 5ft, coming from the WSW. But don’t get excited. The wind is a messy cross-shore, 15 mph, and the whole thing is just a chopped-up, lumpy mess. The energy is weak (355), and the conditions are poor. This isn’t surf, it’s a washing machine. That pretty much sets the tone for the next week and a half.
From Wednesday the 9th right through to the 20th of September, it’s a wasteland. Swell drops right off, mostly below 3ft, and the period is short and weak. The wind hardly ever gives us a break, mostly cross-on or onshore, keeping everything choppy and unrideable. The combined energy rarely gets above 100, and when it does, like on Friday the 11th (339), the wind is still cross or cross-off, making it messy. There’s a brief moment on Sunday the 13th where the energy climbs to 369 with 4ft of swell, but the wind is light cross-on, and the forecast only calls it “marginal.” It’s not worth the drive.
There’s a glimmer on Thursday the 17th of September. The wind goes light and cross-off, and the waves are 3ft to 3ft from the W. The comment says “surfable waves but very ordinary conditions.” That’s the absolute best on offer, and it’s not saying much. The energy is low (129 and 121), and the period is a short 8 seconds. It’s a cruiser for a beginner if they’re desperate, but that’s about it.
After that, it flatlines again. We get a few glassy afternoons on the 18th and 19th, but the swell is a pathetic 1ft to 2ft. You’d be bobbing around on a lake, not surfing. The long-range forecast into the 20th and 21st of September shows a bit of a spike in period (16 seconds!) but the swell height is only 1ft with a strong cross-wind, so it’s all show and no go.
The bottom line is this: Southerndown has nothing on offer for the foreseeable future. It’s a blank run that’s more normal for this area when the summer patterns fade. Don’t bother checking the cams. Leave the boards in the car and go do something else. Forecasts can change, but right now, it’s a total dud.

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 Southerndown 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.
