Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Right then mate, Rusty here. Let’s have a look at what Trearddur Bay (Holy Island) has got cooking for us over the next couple of weeks. I’ll be straight with you – this look is a bit of a tough one. We’ve got a massive stretch of time where the surf just isn’t going to play ball. The water’s sitting at a touch warmer than usual for this time of year, running 63°F.

We kick off from the 25th of August and honestly, it’s a slow burner. For days on end we’re seeing tiny waves and poor conditions – mostly below 1ft. The wind is all over the place, and although we get some nice light breezes, the swell just isn’t there to make anything of it. There’s a long gap with no real surf on offer until we get towards the end of the month.

The first sign of life comes on the morning of Sunday, the 30th of August. It’s not a classic, but it’s the best on offer so far. We’ve got a 3ft SW swell, with a period of 9 seconds, and the wind goes glassy. The combined energy is a moderate 101, so there’s a bit of push behind it. It’ll be surfable but very ordinary. The wind is light out of the WNW, so it’s pretty much glassy. The problem is the break itself is inconsistent, so you might have to wait a while for a set. The water temperature is still a touch warmer than usual.

Tuesday the 1st of September sees a jump in size, with 5ft in the afternoon, but the wind’s a messy onshore from the WSW at 16 mph, so it’s poor. That trend continues – we see bigger lumps, like 8ft on the 3rd of September, but again, hammered by horrendous onshore gales. The swell energy gets strong at 758, but with wind like that, it’s a write-off.

If you’re an expert and you fancy a real challenge, the morning of Saturday the 5th of September throws up a weird one. A long-period 14-second groundswell from the SW, but it’s only 0.3ft. Very long period, very small, with a fresh cross-shore wind at 19 mph. It’s probably more interesting to talk about than to surf.

By the 6th of September afternoon, we get a 7ft SSW swell, but it’s cross-onshore and choppy. Then on the 7th of September, things get serious, but not in a good way for paddle surfing. We’ve got a massive 12ft SSW swell with gale-force cross-onshore winds. The combined energy is a very strong 1338. That’s kite-surfing territory, not for a surfboard.

So, to be honest, there are no true standouts in this whole 16-day window. It’s a blank run. For a spot like this, that’s just how it goes sometimes. The forecasts can change, but right now, there’s nothing to get excited about.

Rusty.
