The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Langland Bay over the next couple of weeks.
Honestly, it's a tough stretch. The overall pattern is one of persistent small, weak swell and tricky winds. The combined energy of all swells directed here barely cracks into the moderate range for most of the period, with values in the 30–90 range (weak energy) for the first week and a half. It’s a real grind, with day after day of “poor surf conditions” or “very ordinary conditions.” There’s a long gap of nothing worthwhile from now until the morning of Friday, 21st August. Even then, it’s just surfable, not good.
That Friday morning, 21st August, is the first real glimmer. We’ve got 3ft of swell from the west at 6 seconds, but the wind is a gentle offshore from the NNW at 15 km/h, making for clean conditions. The combined energy is still weak at 85, so don’t expect a lot of push, but it’ll be a window of something to sit on your board and catch a few.
The next standout, and honestly the best of this whole outlook, is the morning of Monday, 24th August. You’re looking at 4–5ft of swell from the WSW, with a 7-second period and a combined energy that jumps up to 178 (moderate energy). The wind is glassy – NNW at just 5 km/h. That’s dead calm, offshore. For Langland Bay, that’s a rare treat. The wave direction matches the optimum from the SW, and the offshore wind will have those little lines peeling as clean as anything. It’s not a giant day, but for quality and cleanliness, that’s the session to target. The water temp is about average for the time of year, no anomalies to report.
Looking further out, the morning of Sunday, 30th August, shows a bigger pulse: 6ft from the WSW at 7 seconds, with a combined energy of 286. That’s the strongest energy in the 16-day window by a long shot. The wind is a moderate offshore from the NNW at 25 km/h. That’s a promising combination – proper waves with clean wind. At 6ft, it’s pushing a bit for beginners, but for the intermediate crew, that could be a good, punchy day at Langland. Just keep in mind it's a long-range call, so less certain.
The bottom line: a lot of flat, small days to get through. The glassy Monday 24th is the one to circle on the calendar if you can wait. The bigger Sunday 30th is an exciting maybe for later.

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.
