Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Right then, let’s have a look at what’s on the cards for Trearddur Bay over the next couple of weeks.

To be honest, folks, the outlook is a bit of a flat spell for the most part. We’re looking at a long stretch of tiny, poor surf conditions that doesn’t really offer much for a paddle. The first proper recommendation doesn’t show up until way later, so don’t get your hopes up for the next week or so.

The water temp at Trearddur Bay is sitting at 62°F, which is a touch warmer than normal for this time of year.

We start with a few days of incredibly small waves, only 0.3ft, coming from the south with an 11 second period, but the wind is cross-off from the NNW at 12-16 mph, and the combined energy is just a measly 2-6. It’s clean but there’s no power there. From the 20th of July right through to the 24th, it’s a total write-off. The swell dies completely, with zeros across the board. A real flat patch.

On the 24th of July, Friday, we see a tiny bit of life, but it’s still only 0.3ft, and the wind turns onshore, making it choppy. Not worth getting wet for. The 25th and 26th bring a little more height, up to 2ft on the Saturday morning and 3ft on the Sunday morning, but it’s a short-period, windswell of 4-5 seconds coming from the WSW, and the wind is onshore and strong, even with heavy rain on the Saturday afternoon. The combined energy is low, between 19 and 46. It’s messy.

The situation doesn’t improve for the next few days. The 27th through to the 30th of July sees heights between 2ft and 4ft, but the period is still short (4-6 seconds), the wind is onshore or cross-onshore, and the conditions are choppy and poor. The best of a bad bunch might be the afternoon of the 30th of July, where the wind swings light cross-off from the ESE, giving clean conditions, but the swell is only 3ft with a weak 37 energy.

The first real standout, and the only one worth considering, arrives on the 31st of July, Friday. The morning sees a clean 1ft swell from the SW with a 6 second period, but the wind is a beautiful offshore from the NE at 12 mph. The conditions are described as “moderate offshore and clean”. The combined energy is low at 11, but for a beginner spot, with offshore wind, it’s about as good as it gets in this window. The afternoon stays clean with offshore winds, too.

The 1st of August and 2nd of August continue the theme of clean, offshore winds, but the swell drops right back down to 1.0ft to 1ft, with tiny energy values. The 2nd of August morning has a slight air, glassy feel, but the swell period is a pathetic 3 seconds.

So, to wrap it up, the only real window to get a clean little wave is the 31st of July. The offshore winds will make it look pretty, but don’t expect any power. For the rest of the 16 days, it’s a case of checking the forecast again later. This is one of those blank runs that’s pretty normal for the area when the swell windows don’t line up.
