Table - best surf conditions forecast for Llantwit Major over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough one. The whole 16-day window is a quiet, flat spell for Llantwit Major. It’s a real struggle out there, with nothing but tiny, weak ripples on the menu. The first solid chance of a wave doesn’t even show up until the 21st of July, so we’re looking at a gap of over a week with absolutely nothing worth paddling out for. It’s a long, dry run.
The first real sign of life comes on Tuesday the 21st of July. It’s still small, with a wave height of just 2ft to 2ft, coming from the W. The energy is weak (22 to 24 in the tank), so don’t expect any power. The wind is cross-onshore, making it a bit bumpy, but it’s at least something to look at. Wednesday the 22nd brings a nice bit of glass on the morning, with a 1ft W swell and a clean, glassy surface. The wave energy is still weak (22), but the conditions are pretty. The real highlight of the whole stretch, if you can call it that, would be Thursday the 23rd of July morning. We get a glassy surface with a 2ft W swell and a period of 6 seconds. The energy is still weak (36), but that’s the biggest and cleanest combo we see across the whole forecast. That’s your best bet, but keep your expectations very low. The water is a whopping 66°, which is a wild 8° warmer than usual for this time of year – that’s a freakish warm patch.
After that, it’s right back to tiny, weak waves with onshore or cross-shore winds for the rest of the month. With such consistently small, weak surf, and the beach/reef setup, this whole period looks more interesting for a kite than a surfboard. It’s just one of those flat spells for the area. Forecasts can change, but right now, it’s a waiting game.
Stay patient,
Rusty
