The Lowdown
Alright, surfers, Rusty here. Let's be straight with you: looking at this 16-day window for Langland Bay, it’s a tough stretch. The models are showing a whole lot of "poor surf conditions" with not a single standout session to get genuinely excited about.
Right now, the water is sitting at a very unusual 70°, which is a massive 9° warmer than normal for this time of year. That feels more like the Med than the Bristol Channel, but it doesn’t help the waves any.
For the first week, from the 16th right through to the 25th, it’s a flat or near-flat run. We've got tiny waves, mixed with messy cross-shore winds. The combined wave energy is mostly in the double digits, sometimes just scraping into the low hundreds, like on the 18th morning (109), but the swells are short-period wind slop, barely pushing 4 ft. There’s nothing to ride. The 21st Friday morning gives us a brief window of light offshore wind from the N, but with the swell only 2 ft and period at 7 seconds, it’s still essentially flat.
We finally see a pulse around the 26th Wednesday morning, with the swell bumping up to 4 ft from the WSW (108 combined energy). It looks clean, but the overall comment is "surfable waves but very ordinary conditions" – a 1 out of 10. That's as good as it gets. Still, it’s the first thing that’s even worth paddling for in over a week. The wind is light and cross-off, so shape might be okay for the size.
After that, the end of the month gets bigger, but also uglier. By the 29th Saturday afternoon, it’s pumping to 8 ft from the SW – a solid bump that pushes the combined energy to 943. That's proper energy, but it’s going to be a total mess with a 18 mph cross-shore making it lumpy and choppy. That size with that wind will be a battle. For anyone looking for a cleanup, the 30th Sunday morning has 5 ft and 571 energy, but again it’s with a strong 28 mph cross-shore. That’s kite-surfing territory, not a grovel session for a shortboard. Honestly, for the whole run, there’s no one spot or standout day I can point to and say, "Go there." It’s a waiting game.
Stay patient,
Rusty

Information about the Langland Bay Surf forecast
The above surf forecast table for Langland Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Langland Bay can be found by selecting the local surf guide option on the grey menu. Our Langland Bay 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 (Langland Bay) 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 Langland Bay 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.
