The Lowdown

Alright, let me tell you how it is for Southerndown over the next couple weeks.

Honestly, mate, it’s a tough one. Looking at the whole run, there’s really no time where I’d tell you to drop everything and get wet. The pattern is consistent in a bad way: we’ve got a lot of onshore wind, strong wind, and blown-out conditions. The first good sign doesn’t pop up until Saturday the 5th of September in the morning.

We’ll have a real quiet start. Nothing to recommend from Thursday the 27th all the way through Friday the 4th of September. That’s over a week of poor surf and messy winds. The swell is there on some days, but it’s ruined.

Now, that Saturday the 5th of September morning – that’s the one flash of hope. We get a glassy morning with the wind going calm, and a little 3ft swell rolling in from the WSW. The combined energy is weak at 136, but hey, it’s clean. The wave comment even says "surfable waves." It’s not going to be big, and it’s a beginner break anyway, but for the learner or the longboarder, that’s your window. The water temp is sitting at 68°, which is much warmer than normal for this time of year, so it’ll be a pleasant dawn paddle.

After that Saturday morning, it’s straight back to mediocrity. The wind picks up again, and the quality drops right off. The rest of the second week is a write-off with onshore winds and messy conditions. There’s even a moment on Saturday the 5th afternoon with 4ft swell, but the wind is light cross-shore, and the energy drops to 96, so it’s not doing much.

So, if you’re desperate, circle that Saturday the 5th of September morning. Be there at first light when it’s glassy. It’s not a standout by any stretch, but it’s the only clean moment in a very long, poor run.

Information about the Southerndown Surf forecast

The above surf forecast table for Southerndown provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Southerndown can be found by selecting the local surf guide option on the grey menu. Our Southerndown 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. If you surf the same spot (Southerndown) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
