Rhosneigr Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s break down what’s going on at Rhosneigr. I’m not gonna sugarcoat it — this 16-day outlook is a tough one. There’s a long stretch at the start with no real surf on offer. The first decent session doesn’t show up until well into the second week.

The water temperature is sitting at 63°F, which is a touch warmer than normal for this time of year — nothing crazy, but a nice little bonus if you’re in a spring suit.

For the first week and a half, it’s a battle. We’ve got a mix of small, weak swell and pretty ordinary wind. Thursday the 6th starts with a 4ft NW swell, but the cross-on 25 km/h wind makes it choppy and messy — not worth paddling out for. The rest of that week and into the next is just a series of tiny, short-period waves with onshore or cross-onshore winds. The combined wave energy is barely registering, often below 100 (e.g., 78, 22, 15), which tells you how weak it is. There’s a brief moment on Monday the 10th morning where it goes glassy, but the swell is only 1ft with a 6-second period — basically a flat lake.

The standouts — and I’m using that term loosely — don’t arrive until Sunday the 16th. That morning, we see a 2ft SW swell with a 6-second period pushing a combined energy of 51 (still weak). The wind goes glassy, so the conditions will be clean. But the swell is tiny, and it’s only a 1/10 score. It’s surfable, but you’ll be working for every bump. The real kicker, if you can call it that, comes on Wednesday the 19th. That morning, a 4ft SW swell rolls in with a 7-second period, and the combined energy jumps to 174 (moderate). That’s the biggest energy we see in the whole period. The wind is cross-on at 20 km/h, so it’ll be a bit lumpy and choppy, but there’s actually some push behind it. That afternoon, the energy drops to 127 but the swell stays around 3ft. For this stretch, that’s your best bet.

If you’re a beginner, the 4ft swell on the 19th isn’t too big, but the choppy conditions will make it tricky. For experts, there’s nothing here that’s going to get your heart racing. The swell direction is SW, which is what Rhosneigr is looking for, but the short period (7 seconds) means it’s not going to have much shape or power. It’s a beach break setup, so the shorter period can actually work in your favour for more manageable waves, but don’t expect any barrels.

Thursday the 20th drops off again, with a 3ft SW swell and cross-on wind, energy down to 67. By Friday the 21st, we’re back to tiny, weak stuff.

Overall, the only real standout in this 16-day window is the morning of Wednesday the 19th — the closest thing we’ve got to a proper surf. The glassy session on the 16th is worth a mention for a clean, if gutless, paddle. The rest? It’s a long wait. But the good news is that Rhosneigr is fairly consistent, so a blank run like this isn’t the norm — forecasts can change, so keep an eye on it.

Rusty.
