Alright folks, Rusty here. Let's have a look at what Rhosneigr has in store for us over the next couple of weeks. I gotta be straight with you, the story for this stretch is a long, slow grind of tiny surf. We're looking at a real flat spell, so don't go getting your hopes up.

The water's sitting at a touch warmer than normal for the time of year, about 62°, so that's a nice comfort if you're just going for a paddle.

For the whole first week, from Sunday the 12th right through to the end of that week, it's a write-off. We're talking barely a ripple in the water with combined wave energy readings mostly below 30 – that's zero energy for a surfboard. On Thursday the 16th, we get a moment of glassy conditions in the afternoon, which is teasing, but it's on a tiny 0.3 ft swell. Just not enough to work with.

Into the second week, you'll see a little nudge. By Saturday the 18th morning, we might see 2 ft of swell from the SW with a short 6-second period and only a combined energy of 40. It's still considered poor, but it's the biggest we've seen. By Tuesday the 22nd, we get a pulse of 6 ft swell from the WSW with a period of 5 seconds, giving us a combined energy of 161 (moderate wave energy). For a couple of days there, on the 21st and 22nd, there's some size. But the problem is the wind. It's a steady light cross-onshore from the west and southwest. That’s not cleaning it up, and by Wednesday afternoon the wind turns onshore. That size, over 5 ft, will be a bit much for the beginners, and with that short period and onshore wind, it'll be a messy, lumpy affair.

If it was cleaner, the size might be interesting for a short while, but as it stands, with the poor quality and onshore wind at the point with the biggest swell, this setup looks more interesting for kite surfing than paddle surfing.

After that brief pulse, the surf dies right back off again on Thursday the 23rd, with the energy dropping to 2. So, for the remainder of the forecast out to Monday the 27th, we're basically back to flat, with a couple of days of nothing at all.

Honestly, there's no standout session here. It's a blank run that's pretty normal for this area when the swell windows don't line up. Don't bother packing the board for the next two weeks at Rhosneigr.

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.
