The Lowdown
Alright folks, Rusty here. I'm not gonna sugarcoat it—this whole 16-day period is a bummer. There just isn't any reliable, clean surf on offer at Llangennith (Gower). We're stuck with a lot of messy, wind-blown swell and no real windows of quality. You'll need to be picky if you're gonna paddle out at all.
The first bit is all over the place. There's a marginal window on Friday morning, the 11th, when we have a 4.6ft WSW groundswell with a gentle cross-onshore wind, but it's inconsistent and the energy is just moderate (307). That's the best it gets for a while, and it's not saying much.
After that, it's a real grind. The swell stays around the 6-7ft mark, but the wind is making it a complete mess—cross-on, lumpy, and choppy. The water temp is about normal for this time of year. By the 16th, it’s down to tiny, weak energy (92) and stays that way for a few days. From the 16th through the 19th, it's flat and poor—just nothing to surf.
Then, on the 20th, a bigger pulse of southwest swell shows up, hitting around 6.9ft. The energy jumps to 403, which is solid. But the wind is a moderate cross-shore, so it won't be clean. It's still going to be lumpy and challenging. This is a wave for the experienced crew only, as it's too big for anyone learning. And even then, it's not going to be a pristine day.
The final days just peter out into small, onshore slop. There's a bit more energy on the 22nd (328), but the cross-on wind will mess it up. Honestly, the entire stretch is a struggle. The standout, if you can call it that, is that early morning on the 20th, but it's still not the one to get excited about. This is a real test of patience. The surf could change, but right now, I wouldn't be planning any epic sessions.
Stay stoked, and hopefully, next time will be better.

A general guide to surfing at Llangennith can be found by selecting the local surf guide option on the grey menu.

If you surf the same spot (Llangennith) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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 Llangennith 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
