The Lowdown
Right then, let's take a look at what Llangennith has in store for us over the coming weeks.
Honestly, the next week or so is pretty grim for a proper paddle. We've got some tiny waves and ordinary conditions for what feels like an age. Don't get your hopes up until we get towards the end of the run.
The first bit of half-decent action comes on Wednesday the 12th, with some small clean waves pushing in. We're looking at a tiny 2ft from the WSW, and the ESE wind goes glassy by Wednesday afternoon. It's surfable for a learner or someone on a longboard, but the wave energy is feeble, sitting at about 79 to 96 (moderate energy). Not a standout, just a sign of life.
Then we get a low point for a good few days. Nothing worth rushing for from Thursday the 13th right through to Friday the 21st. It's a long, long wait of mostly poor conditions and tiny swell. The sea is just... flat and messy.
Now, there is a big spike on the horizon. Saturday the 22nd of August morning gets our attention. The swell pushes up to a solid 8ft from the W, with a period of 11 seconds. That's real groundswell energy, peaking at a combined energy of 1783 (very strong). However, the wind is a cross-shore from the NNW at 16 mph, making it a bit lumpy. At that size, it's for experienced surfers only. The afternoon stays solid at 8ft, but still lumpy.
Sunday the 23rd morning drops back to a much more manageable 5ft from the W with a light cross-shore breeze. This is a much better prospect, and the energy is still decent at 279 (moderate). That is your best bet for the whole run at Llangennith. It's not perfect, but it's the most fun looking window by a mile. Keep in mind the crowds can be an issue here, but that's the price for the best wave around.
After that, we're back into small, ordinary surf for the final days of the outlook. The water temp is a toasty 68°F, so at least you won't need a thick suit. That's 6° warmer than usual for this time of year, which is very unusual.
So, to wrap it up: suffer through the flat spell, keep an eye on Saturday the 22nd for the big, expert-only stuff, but pencil in Sunday the 23rd morning as the real standout for a decent session.

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.
