The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for Rhosneigr over the next couple of weeks.
Well, I gotta be straight with you – it’s a tough one. Honestly, the whole 16-day window is a bit of a write-off for any decent paddle surfing. There’s a long stretch of just nothing happening, and the bits that do show a pulse are not worth getting excited about. The first few days have some small swell, but the wind is all wrong, and the quality is just plain poor. From Tuesday the 28th through to Thursday the 31st, we’ve got a mix of messy cross-onshore winds and tiny, short-period windswell energy. The best of that weak spell is Tuesday afternoon, with a combined energy of only 125 (moderate) but it’s a lumpy 5 ft from the SSW with a 5-second period. That’s blown out junk. It’s not surfable; it’s more of a kite session with that wind.
Then we hit a flat spell. From Saturday the 2nd of August right through to the 6th, the energy drops to near zero. There’s literally nothing to ride. The wind goes glassy on Sunday morning the 2nd, but there’s no swell to take advantage of. It’s a dead calm pond. This kind of blank run is a bit more normal for this area, so it’s not a huge shock. The water temp is sitting at 62°F which is a touch warmer than usual for this time of year.
We do get a tiny flicker of hope on Monday the 11th of August, with a 0.7 ft, 6-second swell from the SSW, but the wind is a moderate cross-onshore again. The energy is just 4 (weak). It’s not enough to even bother with. The best chance to see a clean face is on Wednesday the 12th of August, with a light cross-offshore wind from the ENE, but the swell is only 0.3 ft with a combined energy of 3 (weak). It’s flat, clean, and empty.
Truth is, there’s no standout session here. The only swell that ever gets above knee-high is all blown out or short period. If you’re desperate for a paddle, keep an eye on the forecasts – things can change. But right now, I’d leave the boards in the shed.
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.
