The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Abereiddy over the next couple of weeks. I gotta be straight with you – this is a tough stretch. We're looking at a pretty gnarly run of poor surf quality for the next week or so, with only a couple of late whispers of something better.
We kick off on Monday the 31st of August with some lumpy, cross-onshore wind, a 6ft WSW swell at 9 seconds and wave energy sitting at 564 (moderate). The water is a touch warmer than normal at 64°. Honestly, it's a mess. This onshore trash continues through the week; we get some cross and cross-off winds, but the swell is either tiny or just as messy. Tuesday the 1st of September is a write-off with 3ft and a short 6 second period. Even the small window of clean conditions on Wednesday the 2nd has basically no swell – just 0.3ft. For a good long stretch, through to the 7th, it’s just not worth paddling out.
There’s a glimmer on Tuesday the 8th of September. A 8ft swell from the WSW, but with a short 7 second period, makes for a bit of a close-out potential. The wind is clean, which is a positive, but the wave energy is strong at 473. It's a marginal call for a bigger board and a lot of patience.
But if you can hold out, the real standout – and I mean the *only* one that gets the blood pumping – is Monday the 14th of September. Monday morning we see a solid 10ft WSW swell, picking up to 10ft in the afternoon, both with a period around 8-9 seconds. The wave energy is massive, hitting 1159 in the morning and a whopping 1421 in the afternoon – that's very strong energy. The wind is cross-offshore, meaning clean faces. This is a big, powerful swell. At over 8ft, this is for experienced surfers only. The period isn't super long, so it won't be as gnarly to paddle into as a 15-second groundswell, but that size with a cross-off wind at Abereiddy? That could be something special if the tide lines up. Just keep an eye on the crowds, as they might be around for this one.
Before that, the 13th has some strong offshore wind, but the swell is a poor shape for the size. The 15th sees the swell dropping but still clean, so there will be some fun ones in the aftermath.
So, to sum it up: a whole lot of nothing for over a week, then a brief marginal window, followed by one potentially epic day for the big-wave crew. The long-range call for the 14th is promising but less certain this far out, so keep your fingers crossed.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Abereiddy may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
