Rhosneigr Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s be straight with you – the next couple of weeks at Rhosneigr are a real mixed bag, and you’ll have to be patient. We’re staring down a long, bleak stretch of onshore junk before a glimmer of hope shows up late in the game.

The problem right now is wind. For the first ten days or so, we’ve got a solid SW/SSW swell running, but the wind is almost always on it or cross-onshore, and it’s fresh to strong. That means lumpy, choppy, and just plain messy conditions. The water temp is sitting at 63°F, which feels a touch warmer than normal for this time of year, but that’s about the only thing that’s comfortable.

Tuesday, September 1st through to Thursday, September 10th is a write-off. Seriously. We’re looking at poor surf conditions day after day. The swell hangs around waist to chest high mostly (3 ft to 6 ft), and the combined energy (87 to 628) is just getting chewed up by the wind. There’s one moment on Monday, September 7th morning where the wind goes light and variable, but the swell is a pathetic 0.7 ft from the WSW with a long 14-second period – that’s just a lake. Not worth a paddle.

Then we get a bit of a window. Friday, September 11th morning, the wind finally swings around to an ENE cross-offshore, and the conditions go clean. The problem? The swell is tiny, only 2 ft. It’s surfable, but just barely. That afternoon, a clean cross-off continues but the swell drops even more to 2 ft. Saturday, September 12th is even smaller, with a piddly 0.7 ft swell, though it’s clean and even goes offshore in the afternoon. You’d be on a longboard hoping for a ripple.

Now, here’s the standout. Sunday, September 13th is the one to circle on your calendar. The morning brings a clean 6 ft swell from the south with a 6-second period, and the wind is a light cross-offshore from the ENE. The combined energy sits at 227 – moderate and punchy. But the real treat is the afternoon. The wind goes fully offshore from the ENE at 12 mph, and the swell bumps up to a solid 7 ft from the SSW. That’s a serious amount of power, with a combined energy of 471. This is going to be good, clean, offshore surf. The 7 ft size is getting into expert territory, so if you’re not comfortable on a bigger wave, be careful. The period is a modest 7 seconds, so it’s a windswell, not a groundswell, but with that offshore wind, it’ll shape up nicely.

Monday, September 14th is still worth a look. The morning is glassy – 0 mph wind – with a 4 ft swell from the SSW. The afternoon stays glassy with a 6 ft swell. The energy is moderate (179 and 195), and the conditions will be clean, but the waves are just ordinary. Not a standout, but a nice clean session if you’re around.

After that, from Tuesday, September 15th onwards, we slide back into onshore junk and weak surf, closing the forecast window.

So, the one true standout is the Sunday, September 13th afternoon session at Rhosneigr. That’s the one to aim for. The morning of the 13th is also good, but the afternoon is the pick. The rest of the 16 days is mostly a waiting game.

Rusty.
