Rhosneigr Surf Forecast and Surf Report

Alright, folks, it’s Rusty here. We’ve got a bit of a rough stretch ahead for Rhosneigr over the next couple of weeks. Honestly, I’m looking at this forecast and it’s pretty hard to find anything to get properly excited about. The whole 16-day window is a bit of a bust for good paddle surfing, so we need to be patient.

Right now, for today, Saturday the 12th, it’s onshore and messy. We're looking at a 6ft SW windswell with a short period of 7 seconds, pushed around by a 22 mph wind. The water is sitting at 63°, which is a touch warmer than normal for this time of year. The combined swell energy is moderate at best (314), but the quality is just poor.

The pattern continues for the next week. Through Sunday the 13th and into the following week, we’ve got a real mix of small, weak swells and strong, lumpy cross-onshore winds. Swell heights will be bouncing between 2ft and 5ft, but the period is consistently short – usually 4 to 6 seconds – meaning weak, choppy waves. On Tuesday the 17th and Wednesday the 18th, the combined energy picks up a bit to 86 and 124, but it’s still blown out and messy. There’s a period of more onshore wind from the SW on Friday the 18th evening with some 6ft swell and moderate energy (176), but the 22 mph wind is going to make it a washing machine.

Forget trying to get a clean wave in that first week. The setup is more interesting for kite surfing than paddle surfing with all that cross-onshore wind and lumpy water. We get a brief hint of glassy conditions on Wednesday afternoon, the 23rd, with the wind going calm and some 2ft SW swell showing, but the period is only 4 seconds, so it’ll be tiny and weak. That’s the only real quiet moment in the whole window, but it won’t provide any power.

From the 20th onward, the swell just drops off a cliff. For the entire second week, from the 20th of September through to the 27th, it’s all under 3ft, with most days showing less than 1.0ft of swell and very low energy values (1 to 37). The wind tries to go cross-off or glassy occasionally, but with no swell to work with, there’s just nothing to ride.

There’s nothing here to highlight as a standout. The entire period is a write-off for decent surf. It’s one of those blank runs that happens here. Forecasts can change, so keep an eye on it, but as it stands, leave the boards in the van.

Stay patient.

Rusty.
