Alright, this is Rusty, and I've been sifting through the charts for what's on offer.
Honestly, it's a pretty quiet outlook for the next week and a half. We're looking at a real dry spell for the first ten days. From Friday, July 3rd, all the way through to Sunday, July 12th, it's a long stretch of nothing worth paddling out for. The surf is tiny, weak, and messy, with the combined swell energy barely ticking over – you're looking at values of 10 to 40, which is just flat out weak. Plus, the wind is stuck in a cross-onshore pattern, keeping everything lumpy and uninviting.
We finally get a little window on Monday morning, July 13th. Llantwit Major (point) is the only spot that looks like it might turn on. The wind goes glassy, which is a huge bonus, and we'll see a clean little 2ft groundswell from the West with a nice long 12-second period. The combined energy climbs to 91, still weak, but it's a massive improvement. It's going to be small, but clean and rideable for a morning session. The water temp is about average for this time of year, so no surprises there.
After that, it's back to the same old story: onshore winds and a tiny, weak swell right through the second week. By Thursday, July 16th, the swell bumps up a touch to 3ft, but the cross-onshore wind sticks around, and the energy is still only moderate at best. It's nothing to get excited about.
So, bottom line: your only real shot is Monday morning, July 13th, at Llantwit Major. If you can get out for a glassy session on a knee-to-waist high wave, that's the pick. Otherwise, it's a waiting game for a proper swell.

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.
