Table - best surf conditions forecast for Southerndown over the next 16 days.
Alright, let’s have a look at the next 16 days for Southerndown.
I’ll be honest, it’s a grim outlook. The whole 16-day window is mostly flat and frustrating. The water is sitting at 66°, which is a whopping 7° warmer than usual for this time of year – that’s very unusual, feels like a warm bath.
The first week is a total washout. From Monday the 13th all the way through to Thursday the 23rd of July, the waves are tiny, almost non-existent. The combined energy is mostly below 20, which is barely a ripple. The wind is all over the place, mostly cross-off or cross-on, and while it’s often clean, there’s just nothing to ride. There’s a brief moment on Wednesday afternoon, the 15th, where the wind goes glassy at 3 mph from the NE, but with a swell of just 0.3 ft from the SW, it’s a flat, glassy pond. Not even a longboard would get wet.
We get a little flicker heading into the second week. On Friday the 24th of July, the swell tries to push up to 4 ft to 4 ft from the WSW, with the combined energy climbing to 119 (moderate). But the period is a short, weak 5 to 6 seconds. The wind is a nasty cross-on at 16 mph, turning it into a choppy, lumpy mess. It’s only for beginners, but honestly, the conditions are so poor it’s not worth the paddle.
Saturday the 25th sees a drop back to 2 ft from the W, with a clean cross-off wind from the ESE at 6 mph. The energy is weak (44 to 26). It’s clean but tiny. After that, a near-gale from the E on Sunday the 26th (31 mph) blows through, but the swell is only 1.0 ft. The very end of the run, Tuesday the 28th, has 3 ft from the WSW, but with a short period (7 seconds) and a fresh onshore wind, it’s just a choppy, lumpy mess again.
The best on offer? There isn’t a standout. The best conditions for a beginner would be the Saturday morning of the 25th, with clean 2 ft waves and a light offshore breeze. But it’s still tiny. For anyone else, there’s nothing to get excited about. This is a classic blank run for the area; it’s just one of those flat spells.

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.
