Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Alright, Rusty here with the lowdown on Trearddur Bay (Holy Island). Straight up, we’ve got a long stretch of nothing to get excited about. This isn’t a week where you dust off the shortboard.

The first couple of days, right through the 24th to the 27th of August, it's flat, mate. Flat as a pancake. We’re talking tiny 0.3 ft swell – barely a ripple. Don't even bother paddling out. The water’s sitting at a warm 63° which is a touch warmer than normal for this time of year, but that’s about the only positive.

We see a little bump in the swell from Friday the 28th and through the weekend, but it’s crap. The wind is all over the place – cross, cross-on – and it’s just not coming together. The swell height gets up to 6 ft by the 30th, which would be alright, but the period is a short 6 seconds and the wind is a fresh cross-onshore making it a sloppy, lumpy mess. The combined wave energy gets up there, but it’s a waste. If you're into kites, this might be your window, because for a paddle surfer it's junk.

The start of September looks a bit grim. Monday the 1st has some chunky 7 ft swell but it’s paired with a 28 mph cross-onshore wind – strong breeze and messy. That’s expert territory, and only if you’re into a beating. Cleaner conditions show up on Wednesday the 2nd with the wind turning cross-off and 5 ft of SW swell, but it’s still not clean enough to really call good.

Now, here’s the only real standout in this whole 16-day window. Thursday morning, 3rd of September. Don’t blink or you’ll miss it. We’ve got a calm, glassy morning with the wind completely dead. The swell is small, only 2 ft from the SW with a period of 6 seconds, and low wave energy. The forecast says "surfable waves but very ordinary conditions" – and that’s the best we get. It’s a fleeting moment of glass for the beginners out there, but it’s tiny.

After that, the outlook turns ugly again. Through the 4th to the 8th of September, the wind is either onshore or strong cross-onshore, with some proper muscle in the swell. By the 7th and 8th, we’re seeing 7 ft to 8 ft swell, but the wind is a strong breeze or near gale, blowing it to bits. That’s not surfable, that’s a washing machine.

Bottom line: There’s not one solid, clean session to really get your teeth into over this entire stretch. If you’re desperate, the glassy dawn on the 3rd of September is your only real shot, and even that is on the tiny side. Otherwise, keep an eye on the charts, because it tends not to stay poor for long around here, and forecasts can always change.

Rusty.
