The Lowdown
Alright, Rusty here. Let’s chew the fat on Rhosneigr for the next couple of weeks.
I’m not gonna sugarcoat it – the outlook is a total bummer. We’re staring down a 16-day window with not a single surf session worth paddling out for. The whole period is a dud. There’s a faint whisper of something at the very end, but it’s not enough to get the heart rate up.
The big problem is a relentless run of poor conditions. The water is 17°, which is a touch warmer than usual for this time of year, but that’s the only bright spot. The swell is mostly weak and short-period, and whenever there’s a bit of size, the wind is on it. On the 7th of September, there’s a 1.6m SW swell, but the wind is screaming from the SSW at 40 km/h, blowing the surface to bits. The combined energy of all swells directed here is a weak 133, and the guidance is screaming “poor surf.”
It’s the same story over and over. A bump on the 10th gives us a 1.6m SSW swell with a lousy 6-second period, but the wind is a fresh cross-onshore, making it lumpy. The energy hits 160, but it’s a mess. The 12th brings the biggest swell of the period at 1.8m from the SSW, with a combined energy of 211, but the wind is 40 km/h from the south, delivering a strong, messy, cross-onshore chop. That’s more of a kite session than a surf session.
From the 16th onward, the swell completely vanishes. We’re talking tiny 0.1m to 0.3m waves with almost no energy (combined energy values of 1 or 3). The wind does go light and clean, but there’s simply nothing to ride.
The only slim possibility is on the 22nd of September, with a 1.2m SW swell and a combined energy of 105, but the wind is a strong 40 km/h from the west, making it a messy cross-onshore slop. The guidance gives it a zero. It’s a hard pass.
For a spot that’s usually fairly consistent and good for beginners, this is a real dry spell. It’s one of those stretches where the forecast can shift, but right now, the board stays in the car. Not much else to say.
Rusty.

Information about the Rhosneigr Surf forecast
The above surf forecast table for Rhosneigr provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rhosneigr can be found by selecting the local surf guide option on the grey menu. Our Rhosneigr surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rhosneigr) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Rhosneigr may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
