Rhosneigr Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day window on the cards for Rhosneigr, but I’ll be honest with you, it’s a grim stretch. The models are showing a real flat spell, and the only surf on offer is pretty poor quality. So, let’s break it down.

First up, the start of the outlook is a bit of a write-off. We kick off on Thursday, 3rd September, with a small SW swell pushing waist-high at 4ft, but the period is a short, weak 7 seconds. The wind is howling onshore from the SW at 16 mph, making it a total mess. The water is a touch warmer than you’d expect for this time of year, sitting at 63°, which is about a degree and a half above average. The combined swell energy is a low 155 – weak and unappealing. This is a pass for me.

Moving into Friday, 4th September, the swell height bumps up a little to 6ft, but the period drops to a pathetic 5 seconds. The wind cranks up to 22 mph from the WSW, and it’s cross-onshore, producing a lumpy, choppy surface. The combined energy climbs to 157, but it’s all wind-slop (157). Not worth a paddle.

The weekend isn’t any kinder. Saturday morning, 5th September, sees the swell drop to 2ft with a 6-second period, and onshore winds. The energy tanks to 55. By Sunday, 6th September, we see a bit of a bump to 5ft on the afternoon, but it’s still messy with a cross-onshore wind and a combined energy of 164. It’s poor across the board.

The next week looks like a slow slide into flatness. The best of a bad lot might be Thursday, 10th September, when the swell hits 6ft from the SSW with a 6-second period, and the wind is only a light breeze, but it’s still cross-onshore. The combined energy is 211 – moderate at best. It’s not the clean, lined-up waves we want, just a bit of bumpy, weak energy.

From Monday, 14th September, onwards, it’s mostly dead. A few days see a tiny pulse of 1ft from the SSW, but the wind is offshore or cross-offshore, so it’s clean. The problem is there’s no swell to ride. The combined energy is in the single digits. Sunday, 13th September, has a perfect offshore wind from the NE at 16 mph, but the swell is a measly 0.3ft – you’d be floating on a lake.

Right at the end of the outlook, on Friday, 18th September, we get glassy conditions with a light SSW wind, but again, zero swell. The whole period is a bust. There are no standouts, no hidden gems. The only consistent thing here is the inconsistency of the swell. For a spot like this, a blank run is a bit more normal in a flat spell, but it still stings.

If you’re really jonesing for a wave, you’d be better off looking at a kite. The cross-onshore conditions on the days with a bit of size (like the 4th and 8th) are more suited to kite surfing than a paddle board. Otherwise, keep the board in the bag and wait for the next system.
