The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks at Llangennith are looking pretty grim. If you’re after a paddle, you’re going to be waiting a long time.
Right now, and for the next week, there’s pretty much nothing on the cards. The water is *much warmer than normal* for this time of year, sitting at 68°F, which is a weird 9°F above the norm. But that’s about the only interesting thing going on. The wave energy is almost non-existent – we’re talking weak numbers like 17 (combined energy) at best, and most of the time it’s a measly 1 to 3. We’re looking at a long, dry spell with no real surf to speak of. The first recommendation doesn’t come until Saturday the 19th of July, but even then it’s a pathetic 0.3ft of windswell.
The only real blip on the radar comes right at the end of the month. On Wednesday the 29th of July, the morning shows a bit of a pulse with 2ft of swell from the west and a period of 7 seconds. The combined energy finally gets into moderate territory at 35. By the afternoon, it’s a little better with the same 2ft, a period of 10 seconds, and energy climbing to 51. But here’s the kicker – the wind is onshore from the west at 22 mph, which is going to chop it up. It’s a beach break, so with that much wind, the setup looks more interesting for kite surfing than paddle surfing. Thursday the 30th of July offers a cleaner morning with light ESE winds (9 mph) and 1ft of swell, which is about as good as it gets, but it’s still a tiny wave.
Honestly, I can’t point you to a standout session here. The whole period is a bust. For a break that’s consistent and exposed, this is a really poor run. We’d need a serious change in the weather to get anything going. Keep an eye on the charts, but for now, don’t bother waxing up.
Rusty.

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.
