The Lowdown
Alright folks, Rusty here with the long-range look for Southerndown.
Straight up, I won't lie to you, this is a tough one. The next 16 days look flat, real flat. We’ve got a long stretch ahead with barely a wave worth paddling for. The first run of any real note won't come until Thursday the 13th of August. Before that, we're staring at a fair bit of nothing with tiny, weak swell and poor conditions.
Let's break it down. Sunday the 9th through Wednesday the 12th is pretty much a write-off. Swell heights are hovering around the 0.3 ft to 2 ft mark, and the wind is mostly cross or cross-onshore. The combined wave energy is in the weak range, between 3 and 54, which tells you all you need to know – not enough push to get excited about.
Thursday the 13th of August finally offers a glimpse of something. Early morning we get a window that’s *surfable*, but it’s very ordinary. We’re looking at a SW swell of 2 ft with a 9-second period and the combined energy is still weak, coming in at 68. The wind is light and cross-offshore from the ESE, keeping it clean. It’s a beginner-level wave at best. The afternoon gets a little more push, up to 2 ft from the WSW and 82 energy, but the wind swings cross-on, messing up the face. Don't get your hopes up.
From Friday the 14th right through to Monday the 24th of August, it’s more of the same: very small, weak surf with poor conditions. There are a few moments that catch the eye, but they don’t deliver. The Saturday the 22nd morning, for example, has a building 2 ft swell from the W with clean, offshore winds from the ENE – that sounds promising until you see the period is a short 6 seconds and the wave comment says "poor surf conditions." It’s just not got any substance.
The 21st of August Friday morning and afternoon see a consistent offshore wind and a WSW swell at 1.0 ft, but with a combined energy of only 24, it’s just too small. The 22nd Saturday afternoon has glassy conditions, but again, the wave size and period don't match the vibe.
There’s no standout session here. The best you could say is that Thursday the 13th of August early morning is the most *likely* to be surfable, but it’s a beginner wave in weak swell. For anyone else, it's a good time to check the forecasts for a change and maybe work on the wax collection. This is one of those blank runs that feels pretty normal for the area when the conditions just don't align.
Rusty.

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.
