The Lowdown
Hey everyone, Rusty here. Let's talk about what Llangennith is offering up. I'll be honest, it's looking pretty grim. We've got a long stretch of time where the surf is just not gonna be worth the effort.
Right from the start, things are flat. Until the 25th, we're talking knee-high dribble, if that. The wave energy is in the weak range (14), so don't even bother. The water's feeling like a bathtub at 69°, which is a wild 8° warmer than normal for the time of year.
We finally get a pulse on the 26th, but it's a write-off. The wind is hammering onshore from the WNW at 19 mph, making for lumpy, choppy waves. The swell does get to 5ft, with moderate energy at 225, but it's blown to bits. For a beginner spot, that 5ft is already getting big, and with that wind, it's not a place to be.
The 27th gives us a 3ft swell with a light cross-on breeze, but the forecast calls it "marginal" and the energy is weak at 51. The period is a short 6 seconds, so the waves will be weak and crumbly.
From there, it's back to small and weak until the 1st of August. On the 1st, we see a 4ft bump in the afternoon, but it's cross-onshore with moderate chop and a moderate 113 energy reading – still poor quality.
The best bet, and I use that term loosely, is the morning of the 2nd of August. The swell holds at 4ft, period stretches to 8 seconds, and the energy is at 191. The wind is onshore but lighter. It's still marked as "poor," but it's the most water moving we'll see. Honestly, with the wind and the beachbreak setup, this stretch is looking way better for kiting than surfing.
After that, it fades back to flat for the second week. Consistency is low, and that's just how it goes around here sometimes.
Hang in there, the charts can always flip.
Rusty.

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

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.
