Table - best surf conditions forecast for Llangennith over the next 16 days.
Right then, Rusty here again. Let's cut to the chase. The next 16 days are looking bleak for Llangennith.
We're staring down a long, flat spell. From now until around the 19th of July, expect about 11 or 12 days of nothing but millpond conditions. The water is unusually warm for the time of year, running at 20°C, about 5 degrees warmer than normal. That's a weird one.
The first chance you'll get, and it's a slim one, is on Friday the 10th of July. We might see some 2ft swell from the west, with a 9-second period. The morning has a light offshore breeze from the east, so it should be clean, but the energy is weak.
That window slams shut quickly. After that, it's dead flat until the afternoon of Sunday the 19th of July. That afternoon shows a 3ft west swell, but with a short, weak 6-second period and a strong onshore wind. Expect messy, choppy conditions. Not worth it.
The best of a bad bunch is Monday the 20th of July morning. You'll have a light offshore breeze with a small 2ft west swell and an 8-second period. It's surfable, but just barely.
Honestly, don't get your hopes up. For a break that's usually reliable, this is a proper flat spell. On the few days with any wind, it looks like it would be better for a kite than a surfboard.
I'd say take a break. Forecasts can change, but for now, it's a total blank.
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.
