The Lowdown
Alright, let’s get real about Rhosneigr. I’ve looked at the next 16 days, and to be honest, it’s a tough stretch for paddlers. The whole window is a flat spell with poor conditions. The first proper recommendation doesn’t even show up until the 24th of July, and even then it’s tiny. Basically, we’re looking at over a week of nothing before we get a pulse.
The first sign of life is Friday the 24th of July at Rhosneigr. The swell is a pathetic 0.3ft from the south, with a period of 13 seconds. That’s a long period for such a small wave, meaning it’s a groundswell trying to push through, but the combined energy is a measly 3. It’s a long wait between sets for a dribble. The wind is light cross-on, so it’ll be clean but tiny. Not worth a paddle.
Saturday the 25th sees a shift. The morning is still onshore and weak, but the afternoon brings a tiny bump to 2ft from the southwest, but with a period of only 4 seconds – that’s windslop. The energy climbs to 19, but it’s a messy, onshore affair. The wind is straight onshore, so it’s going to be a bumpy, blown-out mess.
Sunday the 26th and Monday the 27th are more of the same: cross-onshore chop, swell heights barely breaking 3ft with periods of 4-5 seconds. The energy on Monday afternoon hits 64, but it’s all wind energy, not surfable waves. The water temp is about average for the time of year, so nothing unusual there.
The real spike comes in the final days of July and into August. Wednesday the 31st of July we see a notable increase in swell height, hitting 6ft out of the southwest, period 6 seconds. The combined energy jumps to 270 – that’s moderate wave energy. But the wind is a fresh cross-onshore, making it lumpy and choppy. That’s a lot of water moving around, but it’s going to be a washing machine. This is more of a kitesurfer’s window than a paddle surfer’s.
Saturday the 1st of August and Sunday the 2nd of August keep the energy up, with 6ft and 5ft swells from the northwest and southwest, and energy readings in the 200-300 range. But again, the wind is on or cross-on, and the period is short, around 5-6 seconds. It’s not clean, it’s not well-shaped, and it’s too big for beginners at over 5ft. For the experienced crew, it’s just a messy, powerful windswell.
After the 2nd of August, it drops off a cliff. Monday the 3rd and Tuesday the 4th drop back to 0.3ft or 0.7ft with almost no energy. Tuesday the 4th has a clean offshore wind from the NE, but with no swell, it’s a flat, glassy lake.
The rest of the run into the 6th of August is flat and poor. There’s no standout session here. The only thing to note is that the big pulses on the 31st of July and 1st of August have energy, but the wind direction ruins it. If you’re a kitesurfer, that might be your window. For a surfer, it’s a hard no.

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.
