Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Trearddur Bay (Holy Island) has in store for us over the next couple of weeks.

Straight up, it’s a tough start. The first week and a bit is pretty grim. We’ve got a long stretch of days with barely a ripple, and the wind is all over the shop. There’s a lot of cross-offshore breezes and even some glassy conditions early on the 23rd of August, but the swell is just a tiny 0.3ft from the SW. It’s basically a lake. You’d be better off finding a rock pool. That poor run carries right through until the 25th, with only a slight bump in energy on the 23rd when the wind goes glassy, but there’s still no wave to speak of.

Things start to get a bit more interesting on the 26th of August. We see a jump in swell to 2ft from the S, with a weak period of 4 seconds, but it’s a messy cross-onshore wind. The energy is still low (27). By the afternoon, it builds to 4ft from the SSW, but it’s a short-period, wind-affected mess with a strong 19 mph cross-onshore. It’s not really surfable for a paddle board.

The 27th of August morning offers a glimmer. The morning is glassy with a 3ft SSW swell and a period of 8 seconds. The combined energy is 93, which is weak, but it’s the cleanest conditions we’ve seen. It’s surfable, but ordinary. The wind swings onshore in the afternoon, so that window is tight.

The 30th of August brings a bigger bump – 5ft of SW swell with a 7-second period, and a moderate energy level of 268. But the wind is a strong cross-onshore, 16 mph, with rain showers. It’s going to be a choppy, lumpy mess. Honestly, with that setup, it looks more like a kite surfing day than a paddle surfing day.

Now, the real standout. Mark your calendars for the 2nd of September. That’s a full week away, but it’s promising. We’ve got a solid 8ft swell from the SW, with a period of 7 seconds, and a very strong combined energy of 757. The wind is offshore from the NE in the morning, swinging to a gentle offshore in the afternoon. That’s a lot of water, and it’s going to be big. For a beginner spot like this, 8ft is expert territory. The water temperature is about 63°F, which is a touch warmer than usual for this time of year.

The 3rd of September is still decent, with a 6ft swell from the WSW and a moderate offshore wind, but the energy drops to 202. It’s a step down from the day before, but still a fun option if you missed the big one.

After that, the swell fades again into the 4th and 5th of September, with smaller, cleaner but weak waves. The 5th of September is a 2ft SW swell with a light cross-offshore wind, but the energy is tiny.

So, the bottom line: the first week is a write-off. The best bet is the 2nd of September for the big, clean, expert-level swell. The 3rd of September is a solid second choice. Everything else is a mission.

Rusty.
