The Lowdown
Right then, let’s have a look at what’s on the cards for Southerndown. I’ll be straight with you—this is a tough stretch. The whole 16-day window is looking pretty flat, with barely a pulse of energy. You’ll be waiting a long time before anything even remotely worth a look shows up.
The first real sniff of any action isn’t until Thursday, 13 August, and even then it’s a struggle. The morning brings a tiny 2ft swell from the WSW, with a period of 9 seconds and only moderate energy (67). The wind is light and cross-offshore from the ESE, so it’ll be clean, but the waves are just surfable—very ordinary. This is a beginner-friendly break, fairly consistent, and the NE offshore wind direction is ideal. But with the swell this small, it’s more of a paddle and a float than a proper surf. The water temp is about average for the time of year, nothing weird.
The only time the swell actually pushes up into something with a bit of grunt is Tuesday, 18 August. The morning shows 5ft from the WSW, with an 8-second period and strong energy (308). That’s a lot of water moving, but it’s a short-period wind swell, and the wind is cross-onshore from the WNW at 15 km/h, making it fairly choppy. It’s big enough to be a handful for beginners, but the conditions are messy. The afternoon stays similar with 5ft from the W and 316 energy, but the wind picks up to 25 km/h, chopping it up further. Honestly, this setup looks more interesting for kite surfing than paddle surfing—strong wind, lumpy cross-onshore, and a beach break that’s not going to hold shape.
After that, it fades back into the doldrums. The rest of the period is mostly tiny, weak, and windy. There’s a brief moment on Wednesday, 19 August afternoon where the wind goes glassy calm, but the swell is only 2ft from the W with 37 energy—barely a ripple. Then again on Sunday, 23 August morning, another glassy window with a 2ft WNW swell, but again, low energy (54) and no push.
To be honest, there’s no standout session here. The best you’ll get is that Thursday 13 August morning for a clean, tiny wave if you’re desperate. For the rest, it’s a long, flat wait. These blank runs are normal for the area, but forecasts can change, so don’t lose hope entirely.
