The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the cards for the local stretch.
To be straight with you, the next week and a half is a tough one for Southerndown. We’ve got a real flat spell on the way, with waves barely cracking 3 feet and most of the time the wind is a mess. The first real surf that’s even worth a paddle is a full week away, on the 7th of September, and even then, it’s not the kind of day you’d drive across the county for. The wind finally cleans up, with a moderate NNW breeze holding it cross-off, but the swell is a weak, short-period 5ft from the WSW. The combined energy is just moderate at 301, so it’s a bit of a messy, gutless groundswell that's going to be tricky to line up on a beach break like this. It starts to break a bit too straight for a punchy wave. Dawn patrol on Monday the 7th is your best bet, but don't expect perfection.
After that, the 8th and 9th of September are small and mostly cross-shore, with the 9th morning seeing a glassy 1ft wave that’s barely a ripple. The 12th of September morning has a small 3ft cross-shore swell with an energy of just 99, and the afternoon cleans up at 3ft from the WSW, but again, it's a long period (9 seconds) swell which can be a bit wonky at Southerndown. The best wave on offer in the whole two weeks is a tough call, but that Monday the 7th is the only stretch with a clean enough wind to make a session safe. There’s nothing outstanding here, folks. The water temperature is about average for the time of year, so no need to worry about a seasonal shock just yet.
The gaps are grim. From the 29th of August right through to the 6th of September, there’s hardly a single window that’s worth a mention. It’s a long, flat spell. The 10th through the 13th of September are also small, so the pattern is long gaps of nothing.
Signing off, Rusty.

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.
