The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for the Llantwit Major stretch.
Honestly, mate, this is a tough one to call. We're lookin' at a solid 16-day window, but the surf is just not cooperating. From now all the way through to around the 13th of August, it’s flat as a pancake. Tiny little bumps, nothing with any push, and what little swell there is gets tangled up with cross-onshore winds. It’s going to be a long, frustrating wait for anyone who's keen for a proper paddle.
The water is absolutely balmy though, much warmer than normal for the time of year, sitting around 69°F with a positive anomaly of about 8°F, so at least the wait will be comfortable.
Finally, on Friday the 14th of August, things perk up a touch. The morning sees a pulse of 2ft from the W with a period of 8 seconds. The combined energy is moderate at best, reading 55. The wind is a gentle cross-onshore, so it'll be a bit bumpy but rideable. Saturday the 15th is a similar story, with a 2ft swell from the W, but a stiff cross-shore wind will chop it up.
There's really no standout session here. Even the best of it is “poor surf conditions.” If you’re desperate for a paddle, the Sunday the 2nd of August through to the 11th of August mornings have some clean, cross-off wind conditions, but with waves barely reaching 1ft, you’re basically bobbing around on a lake.
Because the swell is so small and the quality is low, this spot isn't even worth a mention for kite surfing right now. The best advice I can give is to keep an eye on the charts; these flat spells don't usually last forever.
Rusty.
