Llangennith Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Llangennith over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a tough stretch. We’re looking at a long, dry spell before anything even remotely worth paddling out for shows up. The first real whisper of hope doesn’t come until Wednesday, August 12th, and even then it’s not a barnburner.

The water is cranked up to about 68° which is a full 7° warmer than usual for this time of year. That’s really unusual, feels like a warm bath out there, but it won’t make up for the lack of surf.

For the first week and a half, it’s pretty grim. The wind is howling from the west and northwest, blowing straight onshore or cross-on, and that combined with a short, weak swell makes for messy, blown-out junk. The swell energy is barely registering, with values like 12 to 269 (weak), and it’s mostly a short-period windswell. Even the glassy morning on Sunday, August 9th with a slight air from the NW and only 2ft of swell is effectively flat. You’d be bobbing around on a lake, not a wave.

We get a slight tease on Wednesday, August 12th. The morning shows a bit of life with a 2ft swell from the WSW, period bumping up to 10 seconds, and the energy finally climbing into the moderate zone at 104. The wind is light and cross-off from the SSE, which means clean conditions. The surf report calls it “surfable waves but very ordinary conditions.” It’s not a stand-out, but it’s the first window where you might actually catch a couple of knee-high faders at Llangennith if you’re desperate. It’s a beginner-friendly size, but don’t expect any power.

After that, it turns ugly again. Thursday, August 13th sees a jump in size to 5ft, but the period is a short 8 seconds and the wind is cross-on from the WSW, turning it into a choppy, lumpy mess. The energy is moderate (306-385), but the quality is poor. That kind of close-range windswell with side-shore wind is just a fight.

The only period that has a bit of grunt is the 16th of August, a Sunday. The swell height hits 7ft from the WSW, with a moderate energy of 432-509. But the period is still short (7-8 seconds) and the winds are cross-on from the NW and NNW at 15 mph. That’s going to be a big, bumpy, and unruly beast. For a beginner, that’s way too big (over 5ft) and messy. For an expert, it’s a paddling workout with little reward. It’s more of a kite-surfing setup with that wind and swell combo than a clean paddle-surf session.

The brief clean spell on Monday, August 17th with cross-off winds from the SE is only pushing 3ft, and by Tuesday the 18th, the wind is back up, cranking 18-21 mph from the SW, making it fresh and lumpy again.

So, the honest truth? There’s no standout session here. The only window that’s even close to ridable is the morning of Wednesday, August 12th for the absolute die-hards on a log. The rest is a write-off unless you’re into wrestling blown-out, weak windswell. It’s a classic summer low-pressure pattern, and it’s locking us out. It won’t stay poor forever, but for now, leave the boards in the shed.

Rusty.
