The Lowdown
Alright, let’s talk Southerndown. Gotta be honest, it’s a rough outlook. The water’s sitting at 69°F, which is about 8°F warmer than normal for this time of year – that’s really unusual, feels like a warm summer blanket that won’t leave.
The next 16 days look pretty grim. There’s a long gap of poor surf, with onshore winds messing up the waves for the first week. The only real glimmer is the morning of Saturday, September 5th. That morning, we get a glassy, light wind from the SW at 5 mph, with a small 2ft swell from the WSW at 8 seconds. The energy is weak (83), but the glassy conditions are a big plus. It’s surfable, but very ordinary. The rest of that week is a write-off.
Then from Sunday the 6th all the way through to the 15th of September, the swell just dies. Heights barely reach 0.3ft to 1ft, and there’s almost no wave energy. Even with clean winds at times, there’s nothing to ride – it’s a flat spell. For a spot that’s usually fairly consistent, this is a real bummer. Keep your wetsuit on standby, but don’t expect much until the forecasts shift.

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.
