The Lowdown
Alright, let's get into it. Rusty here, looking over the next couple of weeks for Abereiddy.
Straight up, it's a pretty grim start. For the first week and a half, from now right through until the 21st of September, the surf is just not happening. The wind is all over the shop, mostly onshore or cross-shore, and the conditions are messy. We’ve got a solid week of "poor surf conditions" with moderate to fresh breezes just chopping everything up. You’d be wasting your time for that whole stretch.
Now, the first real glimmer of something surfable comes on the morning of Saturday the 19th. Swell picks up to 8ft from the WSW, with a period of 7 seconds. The combined swell energy is strong at (568). It’s still just a marginal call with a light cross-shore breeze, but it's the first sign of life. The following week continues to be hit and miss, with most days still blown out.
The real standout, and the only one I'd be circling on the calendar, is the morning of Friday the 25th of September. We get a solid 12ft swell from the SW. Sure, that’s huge, and at 12ft it’s for experienced surfers only, no place for learners. The period is a nice long 8 seconds, meaning proper groundswell energy. The combined energy is through the roof at (1599). The wind is a light offshore from the NE, 3 mph. That’s glassy conditions. It’s still rated as marginal in the data, likely due to the size making it tricky, but for a big-wave crew, that morning looks like it could be something special. The water temp is about average for this time of year.
From the 22nd, we get a few cleaner windows, like Tuesday morning with a 4ft swell and a moderate offshore from the SSE, but it's small. Everything else is just too messy or too big with bad wind.
So, to wrap it up: forget the first week and a half. Wait for the 25th of September if you're an experienced charger. There's nothing else here that's worth paddling out for.
Rusty.
