Table - best surf conditions forecast for Llantwit Major over the next 16 days.
Alright folks, let’s break down the next 16 days for your local spot.
Honestly, it’s a tough watch for Llantwit Major. From Wednesday, July 8th through to Monday, July 20th, the swell is tiny – most days we’re looking at 0.3ft to 2ft from the west, with short periods in the 8 to 10 second range. The combined swell energy is really low, often in the single digits to low tens (1 to 39), which is just weak. The wind is clean a lot of the time, and you’ll get some glassy mornings – especially Friday the 10th morning and Saturday the 11th afternoon – but there’s simply no power behind it. It’s a total flat spell.
The water temperature is a big story here: 66°F, which is a massive 8° warmer than average for this time of year. That’s very unusual.
There is one small window of hope right at the tail end. On Sunday, July 19th, the afternoon brings a bump to 3ft from the WNW, with a 6-second period. The combined energy hits 70 (moderate) and the wind goes glassy – calm. The conditions are described as very ordinary, but it’s the most surfable moment in the whole outlook. Monday morning, July 20th, keeps that going with 2ft from the west, a 6-second period, energy at 71, and clean cross-off winds.
That’s your only real chance. After Monday afternoon, it drops straight back to small and choppy. The second week is a write-off – poor surf conditions right through to Thursday, July 23rd.
The only standout is that Sunday the 19th afternoon glass-off. 3ft of WNW swell, 6-second period, glassy. It’s not going to win any awards, but it’s the best we’ve got in a long, flat run. Keep an eye on it.
Stay patient, lads. This kind of blank run is more normal around here, but it won't last forever.
