The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the next 16 days down at Southerndown.

To be straight with you, it’s a tough stretch. The first week and a half is pretty much a write-off for any decent paddle surfing. The wind is relentless, mostly cross-onshore, and the water is a balmy 68°—that’s a whopping 7° warmer than usual for this time of year, which is very unusual. The swell keeps coming but it’s wind-affected and lumpy. We’re looking at combined swell energy that mostly sits in the low to moderate range. It’s just not clean.

The only real glimmer of hope comes in the second week. On Monday, September 14th and Tuesday, September 15th, the wind drops away. Monday morning is glassy, with a 3 ft swell from the WSW at a period of 9 seconds. The combined energy is a modest 143, but with that glassy surface, it’ll be the cleanest we’ve seen. Tuesday morning is also glassy, with a 3 ft swell from the same direction and period, and energy of 103. It’s small, but it’ll be rideable and ordinary.

That’s the best we’ve got, and it’s not much of a standout. For a beginner spot, the swell never gets too big, but the wind just kills it for most of the run. If you’re desperate, go for the glassy windows on Monday or Tuesday morning. If you’re after something more exciting, you might be better off looking at a kite for the many windy days.

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.
