The Lowdown
Alright folks, Rusty here. Let’s get into it for the next couple of weeks.
To be straight with you, this stretch is a flat spell. We’re looking at Llangennith, and I’m not gonna sugarcoat it – for the first 11 days, there’s nothing worth paddling out for. The swell is tiny, mostly under 2 feet, and the energy is weak (values between 7 and 88). The winds are all over the place, often cross-onshore or onshore, chopping things up even when there’s a tiny bump. The water temp is sitting at 66°, which is much warmer than normal for this time of year – a solid 5° above average, so you might not need a thick suit, but you’ll be sitting there waiting for a wave that never comes.
We do see a slight flicker of life around the 12th of August. Wednesday morning, there’s a small 2-foot swell from the WSW, with a short period of 9 seconds and pretty weak energy at 77. The wind is a light offshore from the southeast, so it’ll be clean. But honestly, it’s still very ordinary, barely surfable, and only a 1 out of 10 on the call. Not a standout.
The only real standout window, if you can call it that, is the morning of Thursday the 13th of August. The swell is still small at 2 feet from the WSW, but the period is 9 seconds and the energy ticks up to 123 (moderate). The wind is light cross-onshore from the WSW, so it’s not ideal, but it’s the best we’ve got. Still, it’s marginal at best, with a score of 1 out of 10. Don’t expect much.
After that, the wind goes bananas on the 14th – strong breeze from the SSW hitting 25 mph, with moderate rain. Not a day for surfing. The rest of the second week drops back into tiny, gutless swell with onshore winds.
So, the bottom line: this is a quiet period for Llangennith. There’s no real standout day. The best bet is a hopeful paddle on Thursday the 13th morning, but keep your expectations on the floor. This area tends to have runs like this, so it’s not unusual. Keep an eye on the forecasts, things can change.
Stay patient, stay salty.

Information about the Llangennith Surf forecast
The above surf forecast table for Llangennith provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Llangennith can be found by selecting the local surf guide option on the grey menu. Our Llangennith surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. 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.
