The Lowdown
Alright, let’s have a look at what’s cooking for the next couple of weeks at Rhosneigr. To be honest, it’s a pretty grim picture. The water’s a touch warmer than usual for this time of year, about 17°, but that’s the only thing that’s not a disappointment. We’re staring down a massive gap of flat, messy conditions. From Wednesday the 5th all the way through to the morning of Sunday the 17th, it’s just poor surf, lumpy cross-onshore winds, and energy levels that are barely a whisper. The combined swell energy is almost always in the weak, single-digit range. There’s no real surf to speak of.
The only thing that even gets a mention is the afternoon of Monday the 17th of August. The swell bumps up to 2.5m out of the NW, with a 7-second period. That’s a hefty wave, but a short-period one, so it’ll be a bit of a close-out. The energy is a strong 622, which is serious. But the wind is onshore from the SW at 20 km/h, so it’s going to be a mess. At 2.5m, it’s strictly for experts, and the wind makes it a real fight. The morning of the 17th has some energy (1.3m, 408 energy), but a cross-shore wind at 30 km/h will make it blown out. For a beginner-friendly spot like Rhosneigr, that whole setup looks more like a kite session than a surf session. It’s a long wait for a rough day, boys.

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.
