The Lowdown
Alright, Rusty here, let’s have a look at what's on the table. Honestly, for the next two and half weeks, it’s a pretty flat stretch. The first real chance of even a ripple doesn’t show up until Thursday the 13th, so we’ve got a solid four-day gap from now with nothing to even think about.
The water temp is sitting at 69.1°, which is a massive 7.9° warmer than usual for this time of year – that’s proper unusual. So you can leave the steamer at home, but you'll be waiting for the ocean to switch on.
The first glimmer of hope lands on Thursday morning, the 13th of August, down at Southerndown. It's a beginner-friendly spot that’s fairly consistent, exposed to the SW, and works best when the swell is coming from the SW. Thursday morning brings a tiny 2.6 ft of swell out of the WSW, with a period of 11 seconds (longer period, more energy per wave). The combined energy is moderate at 130. The wind is light and clean out of the ESE, which will keep the surface glassy. Those conditions are enough to push the rating to surfable but ordinary. However, this is the absolute highlight. The afternoon goes choppy, and after that, it’s back to mostly poor, choppy, or blown-out conditions right through to the end of the month.
There's a bit more size showing up on the morning of Saturday the 22nd of August – 3.6 ft from the WSW – but with a strong 25 mph cross-onshore wind making a mess, it’s not going to be any good for paddling in. The setup is a beach break, so with that much wind and a bit of size, it’s really looking more like a kiteboarding session than a paddle surf.
On Sunday the 23rd, there’s 3.3 ft to 3.6 ft of swell, but again, a fresh to moderate cross-shore chopping it up. Nothing to get excited about.
To be straight with you, this forecast is a long dry spell. Southerndown is fairly consistent, so it's a bit unusual to see such a blank run. Forecasts can change, but right now, keep your expectations low.

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.

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.
