Alright, folks, Rusty here. Let's cast an eye over what we've got coming for Llangennith. I gotta be straight with you from the get-go: this is a grim-looking stretch, a real flat spell for the most part. The surf just isn't there for a good long while. We've got a solid block of time with nothing worth paddling out for.
Looking ahead, the first hint of something is way off. We see a small bump of energy on the 21st of July – that's a Tuesday. The swell ticks up a touch, hitting about 4ft out of the WSW, but the wind is a mess, blowing onshore with a fresh breeze. Combined wave energy is moderate at 142, but with that wind and a short, weak period of only 6 seconds, it's going to be lumpy, messy, and not much fun. Honestly, that setup looks more interesting for a kite surfer than for a paddle surfer.
After that, the wind keeps howling onshore through to the end of the month. On Saturday the 25th, we see a big number pop up on the charts – a 8ft swell from the West with energy hitting 1006 (strong). But again, it's blown out by a moderate onshore breeze and has a short, crumbly period of just 8 seconds. That's heavy, messy, and only for the experienced crew, if anyone at all.
The one spot that's on the menu is Llangennith itself. It's exposed to the West, which is our only real swell window here, but the consistency is cruelly let down by the timing and the wind. It's a consistent spot for beginners when it's small, but this whole window is a write-off. There are just no good surf options in this 16-day outlook. It's a dry spell. Sometimes that's just the nature of the place. Forecasts can change, but for now, leave the board in the shed.
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.
