The Lowdown
Alright, this is Rusty checkin’ in from the coast. Let’s have a look at what’s cookin’ for Llantwit Major over the next couple of weeks.
To be honest, folks, it’s a bit of a quiet spell ahead. The water’s sittin’ at a very warm 69°, which is a whopping 9° above normal for this time of year – that’s some seriously unusual bathwater, but it’s about the only exciting thing goin’ on.
We’re lookin’ at a long stretch of flat, small surf. From Sunday the 19th right through to the end of July, the swell is tiny, mostly around 0.3ft to 0.7ft, and what little bump there is gets wrecked by a persistent cross-onshore wind. The energy is weak, rarely crackin’ double digits. There’s a brief moment on Thursday the 23rd mornin’ where the wind goes glassy, but with only 0.7ft of swell from the WNW at a short 4 seconds, it’s barely a ripple. The same goes for the morning of Monday the 3rd of August—another glassy moment, but the swell is still just 0.7ft. It’s a tough run for a point break that needs a bit more push.
The best of a bad bunch pops up on Sunday the 26th and Monday the 27th of July. We see a small pulse of swell, about 3ft to 3ft from the W, with a period of 6 seconds. The combined energy climbs to 75 (Sunday afternoon) and 47 (Monday morning), so it’s not entirely dead. But the wind is on it, blowin’ moderate to fresh cross-onshore, so it’s gonna be choppy and lumpy. Not clean, not fun. For a spot that’s fairly consistent, it’s been a real dry spell. On the plus side, when there’s no swell, the forecasts can change—so don’t give up hope just yet.
This is a beach and reef setup, and with the onshore wind and small, weak swell, it’s honestly lookin’ more interesting for a kite surfer than a paddler.
