The Lowdown

Alright, crew, Rusty here. Let's be straight with you. The next couple of weeks are going to be a test of patience for anyone looking to get wet around here. We've got a long stretch of flat, weak, and messy conditions ahead, so let's break it down.

The whole period starts off pretty grim. For the first week and a bit, we're looking at tiny, short-period leftovers that barely push 2ft, if that. The energy is weak, with the combined swell energy mostly sitting in single digits (2 to 15), and the odd blip up to 74 on the 13th, but it's all messy onshore wind. You'll see more whitecaps than clean faces. The mornings on the 10th and 11th will have some clean, glassy windows, but there's just no swell to work with. It's a whole lot of nothing, honestly.

Things start to look a little more interesting around the 23rd and 24th. We finally see some better energy building, with the combined swell energy jumping to 67 on the 23rd afternoon and then 110 on the 24th morning. The swell direction is still from the W, but the period is short, around 7 seconds, so it's not going to have much punch. The best of the bunch looks like the morning of the 24th of August. The swell is 4ft from the W, with clean, cross-offshore winds from the ENE. It's the only day in the whole window that scores even a 1 out of 10, which tells you how desperate it is. It's surfable, but it's not going to be pretty. The afternoon of the 24th cleans up to glassy with 3ft waves, but that energy is already dropping off.

For the rest of the second week, it's back to the tiny stuff, with the odd glassy morning but no real swell. We're not seeing any of the long-period groundswell that would make this place fire. It's just a poor run of form.

So the only real standout here is the morning of Monday, the 24th of August. It's not a day to call in sick for, but if you're desperate, that's your window. Llantwit Major (Vale of Glamorgan) is a fairly consistent point break, but it's also fairly exposed, so it picks up whatever weak west swell is around. The water is running a very unusual 8° warmer than normal for this time of year, which is a nice silver lining if you do brave it.

Honestly, for most of this period, the setup looks more interesting for a kite surfer than a paddle surfer, with the wind and chop being the main features. Hang tight, it won't be like this forever.

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.
