Table - best surf conditions forecast for Southerndown over the next 16 days.
Alright folks, let's get stuck into it. We're looking at Southerndown, and I gotta be straight with you—this stretch is looking pretty flat for the most part. We've got a long gap with no real surf to speak of. From now through the 22nd of July, it’s tiny. We're talking waves mostly around 0.3ft to 1ft, with weak, mushy energy that won't even get you up on a foamie. The combined swell energy is mostly in the single digits or low teens, and the best we see is a meagre 28 on the 10th of July. That's not enough for a proper surf, just some very small bumps. It's a real bummer.
The water is about average for this time of year. There's no real stand-out period.
Now, the end of the forecast window finally shows a pulse. On Thursday the 23rd of July, things wake up. The morning shows a 4ft swell from the WSW, but with a short period of just 6 seconds and onshore wind from the WSW at 19 mph, it's going to be messy. By the afternoon, it jumps to 6ft from the WSW, still with that same short 6-second period, and the wind picks up to 25 mph onshore. The combined energy hits 225 (moderate wave energy). To be honest, with that wind and short period, it's not going to be a classic Southerndown day. It might be more interesting for the kite crew than for paddle surfing. It's technically the best on offer, but it's far from a standout.
So, the run of poor conditions is normal for this spot when the swell window goes quiet. It just doesn't stay poor for long usually, and forecasts can change, but for now, I'd keep the board in the car and the wax in the shed.

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. 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.
