Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Right then, let’s have a look at what’s on offer for Trearddur Bay (Holy Island). I've got to be straight with you – this is a grim run. The whole 16-day window is a write-off for any kind of decent surf. There’s not a single recommendation in the whole period, and the data backs that up. We’re looking at a solid block of nothing.

From Tuesday the 28th of July, it’s poor. The water is a touch warmer than normal for the time of year at 62°, but that’s no comfort. The swell is weak, with combined energy barely hitting 125 (moderate) on the Tuesday afternoon, but it’s short-period, wind-affected slop. The wind is hammering it from the SSW most of the time, 22 to 25 mph, making it a messy, cross-onshore chop. The swell height tries to get to 5 ft, but with a period of just 5 seconds, it’s just fat, lumpy junk. Not for a paddle board.

Wednesday and Thursday are even worse, with tiny 3 ft to 1 ft swell and feeble energy. The wind lightens up a bit, but the swell is gone. By Friday the 31st through to the 1st of August, it’s the same story – tiny, weak, and poor. The combined energy drops into the teens and single digits.

Then we hit a proper dead zone. From the 2nd of August, we get days with zero swell height and zero energy. Just flat, with light cross-shore breezes making a few ripples on the surface. That flat spell runs right through to the 5th of August, with only a tiny 2 ft bump on the 5th, but it’s cross-shore wind at 22 mph, creating a lumpy cross-chop. Absolutely no good.

The 6th of August sees a clean-up in wind, with a cross-offshore breeze from the NNW, but the swell is only 1.0 ft. It’s clean, but there’s nothing to ride. The same for the 7th and 8th – glassy conditions on the 8th, with a calm wind, but the swell is down to 0.3 ft. It’s a cruel tease.

The second week picks up a bit of wind but still no swell. The 9th of August has strong SSW winds at 25 mph and a total flat spell. The 10th shows a tiny 1 ft swell, but with onshore wind. It’s a hopeless pattern. The 11th and 12th are more of the same – tiny, weak, and clean but empty.

Honestly, for a spot that is inconsistent at the best of times, this is a blank run that is pretty normal for the area. The swell just isn’t there. The only thing worth noting is that from the 6th of August onward, the wind goes clean, even glassy, but there’s no wave to ride. The forecasts can change, but right now, I wouldn’t bother getting the wetsuit on. Save your energy.
