The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s happening on our shores over the next couple of weeks.

Right off the bat, I gotta be straight with you – the outlook for the next sixteen days is a bit of a bummer for Rhosneigr. We’re looking at a long stretch of poor surf conditions with nothing really lighting up the scoreboard. The first few days are a write-off, with a persistent cross-onshore wind and messy, choppy waves. The swell energy is weak, barely pushing 70 to 95 (moderate wave energy) early on, and it just doesn't get it together. We’ve got a bit of a gap here with no real recommendations for a solid session.

The water temp is about average for this time of year, so no surprises there.

The only flicker of hope comes right at the end of the run. On Tuesday, the 18th of August, we see a pulse of swell in the morning with a 6 ft SSW swell (combined energy of 196). That’s the biggest number we’ll see, but unfortunately, the wind is blowing straight onshore and strong at 28 mph. For a beginner-friendly spot, that’s just too much wind and the wave size is pushing the limit. The swell period is a short 6 seconds, so it’ll be a bit of a bumpy, disorganized mess. It’s not a day for a longboard, that’s for sure. If you’re an experienced surfer who doesn’t mind a challenge, you might get some big, blown-out lines, but it’s not the clean, glassy day we’re all hoping for. The setup looks more interesting for kite surfing than paddle surfing.

Honestly, for the rest of the window, it’s a case of keeping an eye on the charts. The consistency is not there, and a blank run like this is more normal for the area when the wind doesn’t cooperate. The forecast can change, but for now, I’d leave the boards in the car and wait for a better day.

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.
