The Lowdown
Right then, let’s have a look at what’s on offer for Southerndown over the next couple of weeks.
Honestly, it’s a pretty bleak picture for us here. We’re looking at a long, dry spell with hardly any surf to get excited about for the entire forecast period. The first proper chance of anything rideable doesn’t show up until Thursday the 13th of August, and even then, it’s a real struggle.
The water is sitting at a very unusual 69°F right now, which is a massive 8°F warmer than normal for this time of year. That’s a proper anomaly.
So, the only moment that even comes close to worth a mention is Thursday morning, the 13th of August. We’ll see a small 2ft swell coming from the WSW, with a period of 11 seconds. The wind will be glassy, which is a major positive. The combined energy is still weak though, at just 88. It’s surfable, but very ordinary.
After that, it’s back to the same story. A few mornings on the 16th and 17th offer glassy conditions, but the swell is tiny—0.7ft to 1ft. There’s a slight bump on Tuesday the 18th with 4ft from the west, but the wind is a messy cross-onshore, and the period is a short 7 seconds, so it’ll be choppy and poor.
We then drift through the rest of the month with small, weak swells and mostly onshore or cross-off winds. A few clean windows appear on the 21st, 22nd, and 23rd with offshore or cross-off winds, but the swell is pitiful—0.3ft to 3ft—with very weak energy. You’d be lucky to find anything rideable.
In short, there’s nothing here that’s a standout. It’s a long stretch of poor surf. Keep the board in the van and watch the forecasts, but don’t hold your breath.

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.
