The Lowdown

Alright, folks, Rusty here. Let’s get straight into it. I’ve got the full 16-day window for Southerndown, and I’ll be honest with you – it’s a tough stretch. The forecast is a long, bleak run of tiny, weak, and mostly choppy surf, with very few windows that even look surfable. There’s nothing here that I’d call a standout, but we’ll pick the best of a bad bunch.

The water temperature is 69°F – that’s 8°F warmer than usual for this time of year, which is well above normal, so at least the water won’t bite.

We start with a big gap. The first few days up to the 12th of August are a write-off: tiny waves under 2ft, short periods, and mostly cross-onshore winds creating choppy, poor conditions. Not worth paddling out for.

The 13th and 14th of August see a slight bump to 2ft from the WSW, but the period is still short (9 seconds) and the wind is onshore, keeping it messy. The combined swell energy is still weak, sitting between 45 and 70 (weak energy). Nothing to get excited about.

The 15th of August Saturday morning offers a small glimmer: a clean window with a light easterly cross-offshore breeze, but the swell is only 1ft and 8 seconds. It’s a gutless knee-high dribbler.

The 17th of August Monday morning sees the biggest push of the entire period, with 3ft from the W and a combined energy of 117 (moderate). But the wind is a moderate cross-onshore at 15 mph, so it’s choppy and messy. It’s the biggest swell, but the quality is poor.

The 19th of August Wednesday is the closest we get to a highlight. Wednesday morning has 4ft from the WSW with a clean cross-offshore breeze from the ENE. That’s your best window for a clean wave. The afternoon goes glassy, with 5ft from the WSW and a period of 7 seconds, making it surfable but very ordinary. The combined energy hits 180 (moderate). This is the best on offer.

The 20th of August Thursday morning has a bigger energy spike at 333 (moderate) with 4ft from the WSW, but it’s a cross-shore wind, so not as clean as the day before.

After that, it fades again. The 22nd of August Saturday morning has a clean cross-offshore wind, but only 2ft and 10 seconds. The energy is low (81). It’s another small, clean one.

The biggest issue here is the consistency. The break is fairly consistent, but the swell just isn’t delivering. For a beginner-friendly spot like Southerndown, the small size (under 5ft) is fine for learning, but the wind and chop ruin it most days. The best bet is Wednesday the 19th. Go early morning for the cleanest lines, or the afternoon for a glassy, if wobbly, 5ft. Don’t expect much.

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.
