The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty grim for Rhosneigr. We’ve got a long stretch of poor surf conditions ahead, with only one real day that’s worth getting excited about, and that’s a week and a half away.
The water is running a touch warmer than usual for this time of year, coming in at about 63°, which is a bit of a silver lining if you’re just getting wet, but it’s not going to save the waves. For the most part, we’re looking at onshore winds and messy, lumpy surf. The energy is weak to moderate at best, and the swell direction just isn’t lining up for the break.
Thursday the 10th brings a pulse of windswell, with waves building to about 6 feet in the morning. But those southwesterly winds are blowing at 25 mph, so it’s going to be a raw, stormy mess. The swell energy climbs to a moderate 204, but the wind is killing it. It’s all churn and no shape. No good for anyone.
Friday the 11th and the weekend are just flat and disorganised. The swell drops off significantly, and we’re talking about knee-high dribble at best. There’s a brief bit of clean surf on Sunday morning with a light offshore wind, but the swell is barely there. It’s nothing to plan a session around.
Then things get properly messy again from Monday the 14th through to Wednesday the 16th with strong winds and rain. The swell kicks around the 3-foot mark, but it’s all short-period, peaky junk.
The energy picks up again on Saturday the 19th, with solid 6-foot swell showing. But again, the wind is cross-onshore and the period is short, making for a choppy, closed-out mess. It looks more like a kitesurfing day than a surf day, to be honest.
Now, here’s the one to mark in your calendar. Sunday the 20th, morning. We’ve got a 6-7 foot swell from the west wrapping into the break, with a light offshore breeze from the east. The energy is strong at 293. It’s the only morning in the whole run with clean, surfable conditions. The swell direction is perfect and the wind will be holding it up nicely. This is your window. There’s enough size to have some fun, but it’s still manageable for confident intermediates.
Right, it’s a long, dry spell before that, but it’s worth waiting for. The Sunday morning session on the 20th is the standout. The rest of the run is skunked.
Stay patient.
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.
