The Lowdown
Alright, Rusty here. Let’s take a look at the next couple of weeks.
Gotta be honest, it starts off real slow. For the first twelve days, from Friday the 7th all the way through to the start of the following week, there’s just nothing doing. Tiny swell, onshore wind, and not a wave worth paddling for. The water’s warm for this time of year, sitting at 68°, but that’s about the only thing going for it.
The first chance of a real session comes on Wednesday the 19th. Llangennith will see a 5ft swell out of the WSW. The combined energy is moderate at 242, and the period is a short 7 seconds, so it’ll be a bit bumpy. The wind is light cross-off from the NE in the morning, which will keep things clean. This is the best we’ve seen, but it’s a bit over 5ft, so it might be a handful for beginners.
The real standout is Thursday morning, the 20th. The swell is about 5ft from the WSW, with a combined energy of 260. The wind is offshore from the ESE at 6 mph, giving you clean, glassy faces. The period is still short at 7 seconds, so it’s not the most powerful, but the calm conditions will make it the most fun session of the whole forecast.
After that, it drops back into small, ordinary stuff. A small 2ft swell on the 22nd with an offshore wind, but don’t plan your life around it. If you’ve only got a couple of days, make it the 19th and 20th.
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.
