Trearddur Bay (Holy Island) Surf Forecast and Surf Report

Alright, let's be real about this stretch of coast. The next couple of weeks are looking bleak for a proper surf. The forecast is a long run of tiny windswell and lousy winds, so you're gonna need some patience if you want to get wet.

We start off on Friday, July 31st, and it's a rough kick-off. Trearddur Bay (Holy Island) has a tiny 2ft swell from the west, but it's a short-period 4 seconds of junk, and that 12 mph cross-on wind is just tearing it up. The combined energy is a weak 10. The water is sitting at 62°, which is about a degree warmer than average for this time of year, but that's about the only positive. It's a no-go.

The whole first week of August is the same story. We get a bit of a flat spell on Sunday the 2nd with clean-looking conditions thanks to a light easterly, but the swell is barely a ripple at 0.7ft. It's cruel. The following days are just a blur of tiny, weak swells with onshore or cross-onshore winds. The short period stuff just has no power. The energy readings are all in the single digits or low teens – pathetic.

There's a tiny glimmer on Saturday, August 8th. We've got a clean 1ft swell from the southwest with a 7-second period, and the wind is a light 6 mph cross-off from the north-northwest. The combined energy is an 18. It's small, but it'll be clean and might offer a few little crumbly waves for a beginner. It's the best of a bad lot.

After that, it's back into the doldrums. The middle of August sees more tiny swells, mostly under 2ft, and the wind is consistently onshore or cross-onshore. There's a period around the 14th and 15th of August where the swell height bumps up to 2ft and 3ft, but it's windswell with a period of 3-4 seconds and the winds are fresh and lumpy. The combined energy only gets to a moderate 35 (max) on the 15th, which is still weak. It'll be a messy, blown-out mess.

Honestly, there isn't one standout session in the whole 16-day window. If you're desperate, the cleanest conditions will be on the 2nd and the 8th of August, but you'll need a longboard and zero expectations. For a beginner, anything over 5ft is too much, but we never get close to that. It's a tough spell. For this area, a blank run like this isn't that unusual. The forecasts can change, so keep an eye on it, but for now, I'd be doing something else.

Rusty.
