The Lowdown
Right then, folks, let’s have a look at what’s on the cards for Abereiddy. I’m not gonna sugar-coat it – the next week and a half is a bit of a struggle. We’ve got a long, quiet spell to get through before any real energy shows up. The water’s sitting at a touch warmer than normal for August, about 64°, so that’s a little bonus if you’re brave enough to get in for the tiny stuff.
The whole forecast period starts with a real flat patch. From Friday the 14th right through to the end of the week, we’re looking at tiny, choppy, cross-onshore slop at best. The combined swell energy is barely a whisper, with readings like 43 and 33, which is just weak. A few days even have a glassy moment on the Sunday morning, but the swell is only 0.7 ft, so you’d be floating on a millpond, not surfing.
We then hit a bit of a bump on Tuesday the 18th, where the swell bumps up to 4 ft but the wind is a fresh cross-onshore, making it ugly. The energy climbs to a moderate 137, but the wave comment says it all: poor surf conditions. This pattern of junk continues for days. There’s a tease on the 26th, with a glassy Wednesday afternoon, but the swell is only 3 ft from the SSW. The energy is 97, which is still on the weak side, and it’s described as “surfable but very ordinary.” Not a standout.
The real action, and the only thing worth getting excited about, is a massive pulse that arrives on Friday the 28th of August. We’re looking at a solid 16 ft of swell from the WSW, with a period of 11 seconds. The combined energy is a staggering 5580, which is very strong. However, and it’s a big however, the wind is forecast to be a fresh cross-shore, turning into a strong cross-onshore, which will absolutely destroy any chance of a clean wave. At this size, over 8 ft, it’s strictly for experts only, and with that wind, it’s going to be a washing machine. This is a proper beast, but it’s a messy one. For the average punter, this setup is far more interesting for kite surfing than paddle surfing.
The only true standout, if you can call it that, is actually the tail end of the period. On Thursday the 27th of August, we get a clean, cross-offshore wind from the south with a 6 ft swell from the SSW. The energy is a solid 202, and the conditions are clean. It’s not huge, but it’s the best combination of size and clean conditions in the entire 16-day window. It’s still a bit big for beginners, but for the rest of you, this is the one to aim for. The rest of the time, it’s a waiting game.
