The Lowdown
Alright, Rusty here. Let’s be straight with you: looking at the whole 16-day window for Southerndown, it’s a tough stretch. Honestly, there's no real surf to get excited about across the entire run. The waves are small, the wind is mostly messy, and the conditions are just not cooperating for a proper paddle session.
We kick off on Saturday the 12th with a 5ft swell from the WSW, but the wind is howling onshore at 22 mph, making it a total mess. The water is sitting at 67°, which is much warmer than usual for this time of year – that’s a wild 6° anomaly, so it feels more like a warm summer bath than autumn.
From Sunday the 13th right through to the 15th, we’ve got small waves, barely cracking 3ft, and it’s all cross-onshore winds. The swell energy is weak. Nothing to write home about.
Midweek, from the 16th to the 19th, the swell picks up a little, hovering around 4ft to 4ft, but the wind stays strong and onshore or cross-onshore – fresh to strong breezes. The wave quality is just poor. A few of these days have swell periods around 10 seconds, which is alright, but the wind ruins it.
From the 20th onwards, it’s a slow slide into flatness. Waves drop below 3ft, and by the 23rd, we’re looking at ankle-slappers of 0.7ft. The wind does go glassy on the 23rd and even goes light offshore on the 24th and 25th, but with only 0.7ft to 1ft of swell, you’d need a paddleboard to even get a glide. The combined wave energy is pitiful.
There is no standout session. Not one day in this entire 16-day window is worth rushing out for. The crowd situation at Southerndown is usually manageable, but that doesn’t matter when there’s nothing to surf. If you’re into kiting, some of those windy, choppy days in the middle might get you going, but for a surfer, this is a blank run. It’s one of those spells where the ocean just shuts down. Forecasts can change, but right now, it’s a solid stretch of flat, blown-out nothing.
Rusty.

A general guide to surfing at Southerndown can be found by selecting the local surf guide option on the grey menu.

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 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.
