The Lowdown
Right, let’s have a look at what’s on the table for Southerndown. It’s a pretty bleak start, to be honest. The forecast is absolutely hammered by onshore winds and messy conditions for the best part of two weeks. The water temperature is sitting at 68° which is a whopping 7° warmer than usual for this time of year—that’s a very unusual anomaly, so you’ll be surfing in a noticeably warm bath compared to the norm.
There’s literally nothing worth paddling out for from the beginning of the period through to the morning of Thursday the 10th of September. That’s a solid eight-day stretch where every session is either too choppy, too lumpy, or just plain flat with poor surf. The odd bit of swell pops up, like on the 4th and the 7th with combined energy readings of 369 and 497 (moderate wave energy), but the wind is cross-onshore and strong, ruining any chance of a decent wave. The first real glimmer of hope comes on the morning of Friday the 11th of September. That’s your standout window. We’ve got a clean, cross-offshore breeze with a 7ft swell out of the west, combined energy of 643—that’s strong wave energy—and a period of 8 seconds. This one is definitely too big for beginners, and with that size, it’s pushing into expert territory given the power. The offshore wind will have those lines clean and inviting.
Following that, the morning of Saturday the 12th of September is also worth a mention. You’ll see a drop in size to a more manageable 5ft from the WSW, with clean conditions and glassy cross-off winds (SE at 3 mph). Combined energy is 310 (moderate), and while it’s not the full-on event of the day before, it’s a solid second option if you missed the early Friday session.
After that, it’s pretty grim again. The wind turns back onshore and messy, with a couple of lumpy, choppy afternoons. The morning of Monday the 14th of September offers some clean, surfable conditions with a 4ft WSW swell, but it’s very ordinary quality. The long-range towards the 16th and 17th of September shows more size, with a 7ft and 8ft SW and WSW swell, but unfortunately the wind is a strong cross-shore mess, making it unsurfable. If you’re not an expert, that Friday the 11th morning is your pick, but it’s a long wait. For this area, a blank run like this is pretty standard when the weather systems line up wrong.
