Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Llantwit Major is a tough one. We’ve got a long, quiet gap at the start. For the first eleven days, from Sunday the 12th right through to Wednesday the 22nd of July, the swell is tiny, barely a ripple. You’re looking at waves of just 0.3ft to 0.7ft, so there’s nothing to ride. The water temperature is sitting at 66° which is much warmer than normal for this time of year, about 7° above average, so it’s a real anomaly. The wind is often offshore or cross-off, keeping things clean, but with no swell to work with, it’s a frustrating wait.
Things finally start to show some life on Thursday the 23rd of July. We get a pulse of 4ft swell from the WNW, but the period is a short 6 seconds, so it’s pretty weak and lumpy. The combined energy is moderate at 118, but with strong onshore winds from the SSW at 22 mph, it’s going to be messy. The wind stays onshore through Friday, and the swell drops back down. The best chance for a surfable wave comes on Sunday the 26th of July. The morning sees a 4ft swell from the WSW, with a period of 8 seconds and a combined energy of 206 (moderate). The wind is unfortunately onshore from the WSW at 22 mph, so it’s going to be rough. This is really the only window where the swell gets close to a size worth paddling out for, but the wind is ruining it. It’s a kite-surfing setup more than a paddle-surfing one.
Honestly, there’s no standout session here. The entire period is a write-off for quality waves. With the break being fairly consistent, it’s a bit of a shock to see such a blank run, but it happens. Forecasts change, so keep an eye on it, but as it stands, I’d leave the board at home.
