The Lowdown
Alright, let me break it down for Southerndown. I'm Rusty, and I've been surfing this stretch for a long time. Over the next 16 days, there's pretty much nothing happening. The first few days are flat—tiny little 0.3ft to 0.7ft waves that won't even break. The wind is mostly cross or onshore, and even when it goes glassy, there's no push. The combined swell energy is almost always in the single digits or low teens, which is super weak. Not a single day gives you a decent wave.
The water temperature is a big deal. On July 16th morning, it's 67°F, which is a whopping 7°F warmer than usual for this time of year. That's a very unusual spike—the sea feels like a bathtub. But it doesn't help the surf.
The only glimmer of hope comes right at the end, on July 31st morning. We get a pulse of 3ft from the WSW, with a period of 8 seconds, and a light north wind giving a cross-off breeze. The combined energy jumps to 76, which is still weak but the highest we've seen. The conditions are clean, glassy even. But it's still a small, short-period swell, and the wave comment says "surfable waves but very ordinary conditions." On a spot like Southerndown, which is a beginner-friendly break with a fairly consistent track record, this is barely worth a mention. The optimum swell direction is SW, and this one is WSW, so not perfect. The crowd factor is "sometimes" so you might have company, but honestly, with waves this small, it's more of a paddle than a surf.
Everything else in the 16 days is poor. From July 16th right through to the 30th, it's all 0.3ft to 3ft with poor conditions. July 25th has a bit more wind (22 mph cross-on) and 3ft, but that's just messy and lumpy. If you're a kite surfer, there might be some wind, but for paddle surfing, it's a no-go. The forecast confidence for the first week is high—it's just flat. The second week doesn't change much. So, I'm sorry to say, there are no good surf options in this 16-day window. Southerndown can be a fun little wave when it's on, but it's just not happening now. Keep an eye on the forecasts, because it tends not to stay poor for long, but for now, save your energy.
