The Lowdown
Alright, Rusty here. Let’s break down the surf situation.
Right now, it’s dead flat. We’re looking at a long stretch of nothing to get the heart pumping. There’s a gap of about nine days with no real surf to speak of.
The first little bit of hope shows up on the morning of Sunday, July 28th at Rhosneigr. The swell bumps up to 4.9ft from the NW, with a period of 6 seconds. That’s a short-period, windswell-type wave, and the combined energy is moderate at 171. The wind is a cross-on from the WNW, which is going to make it lumpy and messy. This is really for experienced surfers only, as it’s on the bigger side, and the quality is poor. The setup here looks more interesting for kite surfing than paddle surfing.
The rest of the period through to August 3rd is a mix of tiny, weak swells, mostly under 1.6ft, and often with short periods and cross-shore or cross-on winds. The water temperature is 63.1°F with a positive anomaly of 4.1°F, which is much warmer than normal for this time of year, but that’s about the only bright spot.
There’s no standout session here. The closest thing to a clean window is the morning of July 19th, but the swell is just 0.3ft from the S – you’d be bobbing around on a lake. The whole forecast is a quiet one. It tends not to stay poor for long, and forecasts can change, so keep an eye on the charts.

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.
