Llangennith Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at the next 16 days for Llangennith. Let’s be straight with each other – it’s a tough run ahead. The whole start of the period is a write-off, with no real surf on offer. The water's sitting at 67°F, which is a full 6°F warmer than usual for this time of year – that’s a very unusual and notable warm anomaly.

We’ve got a long gap here with zero recommendations. The first real chance of something surfable doesn’t even show up until Sunday, September 6th, and even that is just a marginal call. Before that, it’s a lot of small, weak, wind-affected junk. Through the last week of August and into the first few days of September, the swell is either tiny or blown out by strong onshore and cross-onshore winds, with wave energy mostly weak to moderate (values like 15, 19, 35, 48, 133 – all under 150). The swell is mostly from the SW to WSW, but the period is short, rarely getting past 9 seconds, which means weak, crumbly waves.

The standout, if you can call it that, is that Sunday the 6th morning. The wave energy is strong (1000), with an 8ft swell from the WSW at a 9-second period. The wind is a gentle cross-onshore, making it fairly choppy, but it’s the only window where the conditions are even close to worth looking at. It’s still a marginal call, with a tide question mark, but for a seasoned surfer who knows the sandbanks, it might offer a few. For experts only, as that 8ft is pushing it for anyone else.

Monday the 7th is a write-off with strong onshore winds, and Tuesday the 8th has some decent energy – 7ft and 7ft from the WSW, with periods stretching to 11 and 12 seconds – but those fresh cross-onshore winds will make it lumpy and messy. Wednesday the 9th is another marginal morning with a 5ft swell from the WSW, an 11-second period, and a gentler cross-onshore, but it’s nothing to write home about. The afternoons are generally onshore and blown.

Honestly, if you’re in the area, keep an eye on that Sunday the 6th morning, but keep your expectations low. This stretch looks more interesting for the kite surfers, given the consistent strong wind and lumpy, blown-out seas. The rest of the 16 days is a washout for paddle surfing. The long-range stuff on the 8th and 9th might seem promising on paper, but the wind is going to spoil it.
