Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s be straight with you – the next 16 days are looking pretty grim for Trearddur Bay (Holy Island). There’s nothing on offer that I’d be excited to paddle out for, so I’ll walk you through the whole stretch so you’re not left hanging.

We start off on Tuesday, 28th July, and it’s a bust. The wind is howling from the SSW at 22 mph, making the surf lumpy and cross-onshore. The swell is a weak 5 ft, but with a short, weak period of 6 seconds, and the combined energy is only 114 – it’s weak and messy. On the 29th and 30th, the swell drops off even more, barely hitting 3 ft, and the wind stays onshore or cross-onshore, so forget about clean waves. The water temp is sitting at 62°, which is a touch warmer than normal for this time of year, but that won’t help you catch a decent wave.

There’s a big gap with no surf to speak of from the 31st of July right through the 3rd of August. The swell is basically flat, with some days showing zero swell height. A few clean patches of wind pop up on the 2nd and 3rd with cross-offshore breezes, but there’s no wave energy to work with. It’s a total write-off.

Then on Tuesday, 4th August, we see a bump in energy – the combined swell energy jumps to 162, which is moderate, with a 4 ft swell from the SW. But the wind is cross-on from the SSW at 6 mph in the morning, turning into a fresh 19 mph cross-on in the afternoon, so the surf is lumpy and poor. The period is still short at 7 seconds, so it’s not going to hold any shape. The rest of the week stays poor, with small, weak swells and onshore winds. The 8th of August has a brief moment with 4 ft swell from the SSW, but again, the wind is a fresh 19 mph cross-on, making it a choppy mess.

The last few days from the 9th to the 12th of August are tiny and weak, with combined energy readings as low as 1 or 2. There’s a little clean wind on the 9th afternoon from the NNW at 19 mph, but it’s cross-offshore and the swell is only 2 ft – not worth the effort. The whole stretch is a dud.

Honestly, with the constant onshore winds and the lack of any decent swell, this setup looks more interesting for kite surfing than paddle surfing on most days, especially the 4th and 5th of August when the wind is strong. Don’t hold your breath; the forecasts can change, but right now, it’s a solid streak of poor conditions.

Rusty.
