Rhosneigr Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what the next couple of weeks are serving up for us. I’ll be straight with you – it’s not the most exciting outlook we’ve seen, but there’s a sniff of something worth waiting for if you’re patient.

The first week is almost a write-off for anyone wanting a proper surf. We’ve got a run of small, weak swells with a lot of messy onshore wind. The water is sitting at 64°, which is a touch warmer than normal for this time of year – a nice comfort if you’re just having a paddle, but the waves just aren’t there.

Rhosneigr is our only option, but for the first few days it’s rough. Thursday the 27th has a tiny 0.7 ft swell from the SSW with a short 7 second period, and only 7 units of energy – barely a ripple. Wind is offshore from the NE, so it’s clean, but there's nothing to ride.

Friday the 28th and Saturday the 29th see a little bump in size, but the wind swings around and spoils it. By Saturday morning the 29th we get a 3 ft SSW swell with 87 units of energy, and a nice offshore ENE breeze at 12 mph making it clean. It’s surfable, but the conditions are still very ordinary – a low-quality option for a beginner to get wet.

That Saturday afternoon and Sunday the 30th are back to choppy, cross-onshore junk. It stays that way right through the end of August and into the start of September. There’s a big gap here with nothing worth paddling out for. A few spots show clean conditions on the 5th and 6th of September with light offshore winds, but the swell is tiny – 3 ft and less than 30 units of energy. Don’t get your hopes up.

Now, here’s where it gets a bit more interesting. Around the 7th of September, we start to see some better energy pushing in. On Monday morning the 7th, the swell jumps to 4 ft from the SW with an 8 second period and 138 units of energy. That’s moderate energy, but the wind is light and cross-shore – still a bit lumpy, but a step in the right direction.

The best on offer in this entire forecast comes on Tuesday the 8th of September. Rhosneigr gets a 4 ft SSW swell with a 5 second period (short period, so not much shape) but the key here is the wind. We’ve got a gentle offshore breeze from the ENE at 9 mph, keeping the surf clean. It’s only 79 units of energy, so it’s not pumping, but after all the junk, this is the one session to target. It’s a beginner-friendly size and the conditions will be tidy.

After that, the swell picks up size but the wind turns against us. Wednesday the 9th sees 6 ft and 6 ft SSW swells with over 220 units of energy – strong, but a strong cross-onshore wind makes it a messy, choppy mess. That kind of size and chop is only for the keenest, and not really fun.

Thursday the 10th and Friday the 11th show some promise with bigger swells – up to 7 ft on the 11th with over 370 units of energy – and clean cross-offshore winds from the NNW and N. That’s decent wave energy, and the wind is clean. But the swell is getting big – 7 ft to 7 ft – so this is expert territory. The breaks at Rhosneigr can handle it, but if you’re not solid, stay out of the way. The period is still only 6-7 seconds, so the waves will be steep and a bit dumpy. Definitely not a beginner session.

So to wrap it up: the first week is mostly a dud. The standout is Tuesday the 8th of September – clean offshore wind, 4 ft from the SSW, and a manageable size for most. After that, the energy ramps up but so does the difficulty. Keep your eyes on the 10th and 11th if you’re a strong surfer, but don’t expect perfection.

Rusty.
