The Lowdown

Alright folks, Rusty here. Let's look at what's ahead for Llantwit Major. I've got to be straight with you – the next week and a half is a tough stretch. We're looking at a proper flat spell, with barely a ripple worth paddling for. The sea looks like it's forgotten how to make a wave.

We kick off on Thursday the 23rd with some clouds and a weak, choppy cross-onshore breeze. Swell is a tiny 0.3ft at 9 seconds from the west, and the combined energy is a measly 2 – that's about as weak as it gets. Things are glassy on Friday morning the 24th, but with that same 0.3ft of swell, it's a flat, clean lake. The weekend offers no hope either, with messy, lumpy conditions and gusty winds making things worse. By Saturday afternoon the 25th, the swell bumps up to 3ft, but with a period of just 4 seconds and a 35 km/h cross-onshore wind, it's a choppy, junky mess, more suited to kite surfing than a proper paddle session.

The pattern of small, wind-affected drivel continues all the way through the end of July and into the first days of August. There are a few glassy mornings like the 28th and 30th, but with swell barely registering, those are days for a swim, not a surf. A few spots show a clean, cross-offshore condition on the morning of Friday the 31st, but again, the swell is just 0.7ft.

Now, there is a flicker of hope right at the end of the forecast window, but it's a long way off. On Saturday, the 1st of August, the morning brings a 5ft south-west swell, period 9 seconds, with light onshore winds. The combined energy jumps right up to 326, showing some real push. The water might be a bit bumpy with that onshore wind, but after two weeks of nothing, this is the one to circle on your calendar. It's still a week and a half away, so don't book time off work just yet, but it’s the only real standout in the whole run. For the rest of it, the water temp is around 69°, which is much warmer than normal for this time of year – so at least the swim will be nice.

The second week keeps things small and ugly. Monday the 3rd and Tuesday the 4th offer next to nothing with poor conditions. Any hope of a late pulse fizzles out by the 7th, leaving us with tiny, lumpy leftovers.

In short, keep your board in the car for the 1st of August, but for everything else, the wax can stay in the wrapper. The only real option is that Saturday morning on the 1st – and even then, keep your expectations in check. Stay patient, lads.

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.

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.
