The Lowdown
Alright folks, Rusty here. Let’s be straight with you. Over the next 16 days, Rhosneigr is pretty much a write-off for any decent wave. It’s a tough one to call, but the data shows nothing but tiny, weak, and mostly messy conditions throughout the entire period. There’s no standout session, no hidden gem of a day to get excited about. The first proper surf recommendation doesn't even appear until well into the second week, around July 27th, and even then, it’s pretty poor.
For the first week and a half, from July 15th right through to the 26th, it’s a long, flat spell. We’re talking waves that are barely a ripple, with swell heights hovering around 0.3 ft and wave energy readings stuck in the single digits (1-15). The wind is often cross-off or clean, but there’s just nothing to push that energy into the beach. It’s a real bummer, a total flat spell for the area.
Now, the second week does see a tiny pulse of energy. On Monday, July 27th, we finally get something to look at. A weak, short-period swell from the SSW pushes in, reaching 3 ft, but the period is a short 5 seconds, meaning it’s going to be weak and crumbly. The combined energy is a modest 33, which is nothing to shout about. The real problem is the wind: it’s a fresh cross-onshore breeze from the WNW at 30 km/h, making it lumpy and choppy. This is more of a kite-surfing setup than a paddle-surfing one.
The following days, July 28th and 29th, offer a tiny bit more, with a 3.6 ft to 3.9 ft swell from the WNW and W. The period remains short at 5 seconds, and the energy builds to 80. Still, the wind is consistently cross-onshore, keeping the surface messy. There’s just no clean, groomed wave in the mix.
The water temperature at Rhosneigr is a balmy 62.8°, which is a whopping 4.1° warmer than average for July. That’s very unusual, and it’s a nice bonus for the long, flat waits.
In short, for the next two weeks, the setup is a blank run. It’s a common pattern for this area. The forecasts can change, but for now, leave the boards at home.

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.
