The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Well, I gotta be straight with you – it's a tough one. The entire 16-day window is looking pretty flat and sad. The swell is tiny, the wind is mostly messy, and there’s just nothing to get excited about. We’re looking at a long stretch of poor surf conditions with no real standouts at all.
Let’s start with Llantwit Major, the only spot on the cards. It's a point break that’s fairly consistent, but it's not getting any love from the ocean. The swell energy is just pathetic, barely hitting double digits most days, with a combined energy value of only 11 on Wednesday the 29th morning. That’s weak. The water temp is about average for the time of year, so nothing unusual there.
Through the first few days, from Wednesday the 29th through to Saturday the 2nd, the swell is tiny – between 0.7 ft and 2 ft – and coming from the west, which is cross-on to the point. The wind is mostly cross-onshore and choppy, making what little wave there is a complete mess. We get a bit of a break on Sunday the 2nd afternoon with glassy conditions, but the swell is only 0.7 ft. It’s clean, but you’d be hard-pressed to catch a ripple.
The whole first week is a write-off. The swell stays tiny, never getting above 2 ft, and the wind is either cross-onshore or light offshore, but with no swell to work with, it doesn’t matter. The energy is low, with values like 15, 32, and 14 – all weak.
The second week, from the 5th of August onwards, is somehow even worse. Swell drops to 0.3 ft or 0.7 ft, with energy values in the single digits. The wind occasionally goes glassy, like on Wednesday the 5th morning and Monday the 10th morning, but there’s nothing to surf. It’s just a flat, calm, empty ocean.
There is a tiny bump in energy on Tuesday the 11th afternoon, with a 2 ft west-northwest swell and a period of 5 seconds, giving a combined energy of 27. The wind is a gentle cross-onshore, so it’ll be choppy and weak. Not worth the paddle.
Honestly, there’s no standout here. The best you could hope for is a glassy session on a 0.7 ft day, but that’s more of a float than a surf. For the next 16 days, the setup looks more interesting for kite surfing than paddle surfing, if you’re into that.
Keep your eyes on the forecast, things can change. For now, I’d say save your energy.
Rusty.

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