The Lowdown
Alright folks, Rusty here. Let’s be straight with you – we’re looking at a pretty grim run for Southerndown over the next 16 days. The swell is mostly small, the wind is all over the shop, and there’s just not a session that gets the heart pumping. I can see a big gap with no real recommendations, and honestly, it’s a tough stretch for the area.
This first bit is a write-off. We’ve got a few pulses of moderate wave energy (up to 372 on the 8th of September), but it’s all messy. The water is a wild 67°F which is a massive 6°F warmer than usual – that’s really unusual for this time of year. But the wind is just not playing ball; it’s cross-on or onshore all the way through the second week. The 8th of September has a 5ft swell from the W, but it’s cross-on at 22 mph, so it’s just lumpy and poor. The 11th of September has a bit of energy (273), but again, cross-on wind ruins it.
Things get a little bit of a breather around the 15th of September. Tuesday morning we get glassy conditions with a 2ft swell from the WSW, but it’s just too small to get excited about. The same goes for the 19th of September – glassy in the morning with a 2ft swell from the W, but it’s a dribbler. The best you could say is that the 22nd of September morning is the only time the score even nudges a 1 out of 10. You’ll see a 2ft WSW swell with clean, cross-off wind from the E at 9 mph. That’s the most “surfable” moment, but it’s still tiny and weak (86 energy).
For the absolute standout, if you’re desperate, the 22nd of September (Tuesday) morning is your best bet. Southerndown itself is a fairly consistent beginner spot, but with a 2ft swell from the WSW and clean wind, it’s the only window where you might get a few small, clean rides. The crowd is "sometimes" here, so you might have some company. Don’t expect anything with power – the period is only 10 seconds, so it’s a weak groundswell. It’s not a barnstormer, but it’s the only thing on the menu.
The rest of the run is a dud. Many days see zero energy, and when there is a pulse, it’s wind-affected. The 15th and 19th of September have glassy mornings, but the swell is just too small. The last few days, from the 20th to the 23rd, the wind goes cross-off, which is clean, but the swell is practically non-existent – we’re talking 0.7ft to 1ft. It’s a long, quiet spell.
Rusty, signing out.

Information about the Southerndown Surf forecast

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.
