The Lowdown

Alright, Rusty here. Let’s talk about what’s on offer at Southerndown.

Truth be told, mate, it’s a pretty bleak stretch ahead. We’re looking at a full 16-day window with not a single standout session. The surf is mostly small, the wind is often a mess, and the whole thing feels like a write-off for anyone wanting a proper paddle. The water is sitting around 69°F, which is much warmer than normal for this time of year – a full 9°F above average – so at least you won’t be cold while you’re waiting for a wave that never comes.

The first week is a right-off. From Wednesday the 5th through to the end of the following week, everything is marked as poor. We get a few pulses, like Thursday morning the 13th with a 4ft swell from the WSW and a 8-second period, and combined wave energy around 192 (moderate), but the wind is a moderate cross-onshore, so it’ll be lumpy and chopped. Friday morning the 14th is similar, 4ft WSW swell with a cross-shore wind, but the cross-chop will make it a bit of a battle.

There’s a brief moment on Sunday morning the 16th of August. We see a 5ft swell from the WSW, a 7-second period, and combined energy hitting 251 (moderate to strong), with a light cross-offshore breeze from the NW. That’s the cleanest wind in the whole outlook, and it’s the only time we see anything described as “clean.” The swell is a bit short-period though, and it’s a beach/reef setup, so it could be walled and a bit fat. This is the only real flicker of hope, but at that size, it’s getting into the territory where it might be too much for beginners. For the experienced crew, it’s the one to watch if the wind holds.

After that, it drops right back off. Monday the 17th brings a small 2ft swell with clean cross-offshore wind, but the energy is weak (68). Then the rest of the second week fades into tiny, messy, or blown-out surf with strong breezes from the W and NW. There’s a solid run of days from the 18th to the 20th where the swell barely scratches 1ft and the wind is either strong cross-onshore or strong offshore – but with no wave to ride, the offshore wind is pointless.

So, bottom line: there’s no real standouts here. If you’re desperate, that Sunday morning the 16th is your best bet for a clean-ish, shoulder-high wave, but don’t expect much. Otherwise, for paddle surfing, it’s a long, flat, and choppy outlook. Honestly, with the wind and the small, weak swell, a lot of these days would be more interesting for a kite surfer than a surfer on a stick.

Keep your eyes peeled for updates, but for now, it’s a lot of sitting and waiting.

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.
