Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Alright, grab a coffee, surfers, and let's get into it. Rusty here.

First thing to say, for the next week we are looking at a bit of a flat spell with some real howling winds. The water temp at Trearddur Bay (Holy Island) is sitting at 63°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus if you are brave enough to get changed.

The next few days are pretty grim. Thursday afternoon's tiny 0.7ft SSW swell gets ruined by a bit of rain. Friday is a write-off with strong onshore winds. The only real flicker of hope comes on Saturday morning, the 29th, with a clean, offshore ENE breeze at 15 mph and a 3ft SSW swell, but the period is a short 6 seconds, so it’s going to be weak and a bit messy. It's surfable but very ordinary. Meanwhile, on Saturday afternoon, the wind swings onshore again, so make the most of the morning.

The rest of the weekend and the start of the week is a washout with onshore winds from the south and west. The swell tries to bump up on Tuesday, 1st September, but the wind is crap. You’ll be staring at a 4ft swell with a pitiful 5-second period on Tuesday afternoon, but it’s cross-onshore and choppy. Not worth a paddle.

We hit a bit of a gap here with no real quality windows. The only real event is a spike of moderate energy on Thursday the 3rd morning, but the wind is a strong 28 mph cross-onshore, making it a total mess. That setup is more interesting for kite surfing than paddle surfing, if you ask me.

Things finally start to look a little more promising as we head into the second week. On the 7th of September, the swell energy picks up, but wind is still a problem. The best window in the whole 16-day run looks like it will be the morning of Tuesday, the 8th of September. We get an offshore ENE wind at 12 mph, with a 4ft SSW swell. It’s clean. It’s not a classic, but it’s the best on offer.

Then we get a bit of a teaser. On the 11th of September, the swell jumps again to 7ft from the SSW, with a cross-offshore NNW wind, and the energy is strong. But the files say it’s still poor surf conditions, likely because the swell is a bit disorganised. Still, it’s a clean, offshore wind and a solid 7ft, so if you are an expert, keep an eye on that Friday morning. The swell will be too big for beginners, sitting over 5ft.

So, the bottom line: there is no standout epic swell here. The best you can hope for is a clean, small session on the morning of Tuesday the 8th of September at Trearddur Bay. It’s inconsistent, so don’t expect a perfect day, but it’s the only decent clean window in the whole 16 days. The rest of the time you’ll be battling the wind.

Rusty.
