The Lowdown
Right then, let’s have a look at what’s on offer for Rhosneigr over the next couple of weeks.
Honestly, I’m looking at this forecast and it’s a bit of a tough one to write. The outlook starts on Tuesday, 21st July, and for a solid stretch of days, there’s just nothing doing. We’ve got clear skies and clean looking conditions, but no swell to speak of – the energy is reading a flat zero (0). It’s a frustrating run of offshore and cross-off winds from the NNW, but the ocean is just flat. That’s the story right through Tuesday, Wednesday, and into Thursday the 23rd of July.
It’s not until Friday the 24th of July that we finally see a pulse, but it’s a tiny one. A long-period groundswell from the south at 13 seconds pushes in, but it’s only 0.3 ft. The combined energy is a measly 3 to 4 – barely a ripple. The wind on Friday morning is a light cross-onshore, but the afternoon looks better with a light onshore breeze from the SW, but the wave state is unknown. It’s still a poor surf day.
The weekend brings a bit more size, but it’s messy. Saturday the 25th of July sees the swell bump up to 2 ft to 3 ft, but it’s a short-period, windswell from the W and SW with a period of only 4 seconds. The energy climbs to 21 (combined energy of all swells directed here), but it’s being blown out by a fresh onshore breeze from the SSW at 18 mph. Sunday the 26th of July offers a 3 ft swell from the WNW with a 5-second period, and the energy hits 62 (combined energy of all swells directed here). The wind is a moderate cross-shore from the NW, leading to a cross-chop. It’s not great, but it’s the most energy we’ve seen.
After that, it drops off again. Monday the 27th of July has a tiny 1.0 ft swell, and the rest of the week into August is a sorry mix of flat spells and tiny, poor-quality windswell.
The water temperature anomaly is not specified, so we’ll just say it’s about average for the time of year.
There is no standout session here. The only real option is the Sunday morning, the 26th of July, with that 3 ft WNW swell. It’s a beach break setup, so that short-period, wind-affected swell will be lumpy. Honestly, this looks more interesting for a kite surfer than a proper paddle surfer with that cross-shore wind and chop.
So, a blank run for the most part. It’s a quiet period for the area.

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.
