The Lowdown
Alright, this is Rusty.
First things first, I gotta be straight with you. Southerndown (Wales) is going through a real flat spell. For the rest of July and into the first week of August, it’s just not happening. We’re looking at tiny waves, messy wind, and a whole lot of nothing. The water is way warmer than usual for this time of year, sitting at 69°, which is a nice touch, but you’ll be floating on a lake, not surfing.
The real story here is the very end of the run. The only thing that gets my heart pumping even a little is the morning of Saturday, the 1st of August. We get a real jump in swell energy (405) with a 4ft groundswell out of the WSW, and the period is a solid 12 seconds. That’s the kind of push that gets the banks working. But the real kicker? The wind is glassy, dead calm. That’s a major positive. You can’t ask for better conditions for a clean surface. The downside is that it’s a long way off, so don’t get too attached yet, but it’s the only window that looks worth a paddle.
After that Saturday morning, the wind swings onshore again and the swell drops back off. The rest of the second week is just a repeat of the first: small, choppy, and not worth the wetsuit struggle. The water does stay relatively warm, but that’s small comfort when you’re fighting a cross-onshore breeze.
So, the bottom line: there’s one very promising, glassy morning on the 1st of August. If you can wait that long, mark it. Otherwise, the next week and a half is a write-off.
Rusty.

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.
