Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
To be straight with you, the outlook for Llantwit Major (Wales) is a bit of a bummer for the next while. We're looking at a long, quiet stretch here. There's nothing worth paddling out for from now until the 20th of July. The swell is tiny, the winds are mostly onshore or cross-onshore, and the wave energy is minimal. It’s a flat spell you might as well spend doing other things.
Things will finally start to look a bit more promising on Monday the 21st of July. The morning should see a bit of a pulse arrive, with swell from the WNW pushing in at around 4ft. The wave energy picks up into the moderate range (97) which is a big step up from what we've seen. The wind is offshore from the ENE at 16 mph, so the surface should be clean. This is the best we've got on offer by a long shot, a real standout in an otherwise bleak outlook. The waves are surfable, but at that size, it's still pretty ordinary and the period is a short 6 seconds, so it won't be holding much shape. Still, it's something to look forward to. The water temp is sitting at about 65°F, which is much warmer than normal for this time of year.
Highlights for the period:
The only real standout is Monday the 21st of July at Llantwit Major. With a 4ft swell from the WNW and a clean offshore breeze, that'll be your best bet for a paddle, even if it's not going to be world-class. It’s not big, but it’s the only solid option we get. Tuesday the 21st afternoon keeps the same 4ft WNW swell and clean offshores from the NE at 9 mph, so if you miss the morning, the afternoon session should still be worthwhile.
Rusty.
