The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Southerndown.
Right off the bat, I’ll be straight with you – this 16-day window looks pretty bleak. The water temperature is sitting at 69°F with a big anomaly of 8°F, so it’s much warmer than normal for this time of year, which is a bit of a surprise, but that’s about the only thing that’s out of the ordinary.
The first few days are a write-off. Sunday the 2nd and Monday the 3rd see tiny swells around 0.7ft to 2ft and poor surf conditions, so don’t even bother. From Tuesday the 4th through to Thursday the 7th, the swell picks up a little but the wind is all over the place – onshore, cross-onshore, and strong – with combined wave energy mostly in the low to moderate range (between 101 and 243), and the surf quality is consistently poor. The whole first week is a dud.
There’s a real gap in the action from the 2nd all the way through to the 15th of August. That’s nearly two weeks of flat, messy, or unrideable conditions. The only faint glimmer comes on Saturday the 15th in the afternoon. There’s a 4ft swell from the west with a period of 7 seconds, light east-northeast winds at 9 mph blowing cross-offshore, and combined energy of 128 – that’s moderate. The surf is still described as “very ordinary” but it’s at least surfable and clean. That’s the best on offer, but it’s nothing to get excited about.
After that, it’s back to tiny, weak swells for the rest of the outlook. The break is a beginner-friendly spot that’s fairly consistent normally, but this run is a real stinker.
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.
