The Lowdown
Right, let’s have a look at the Rhosneigr forecast for the next couple of weeks. I’ve got to be straight with you—this stretch doesn't exactly fire. The first part of the run looks pretty grim, and we’re staring at a long, flat spell before anything even remotely rideable shows up.
The water’s sitting at 64°F, which is a touch warmer than normal for this time of year. You might want a thicker spring suit if you’re out before the sun gets on it, but it’s not too bad.
From Thursday the 27th through to the 2nd of September, it’s basically flat. We’re talking dribbles under 1ft, with weak energy and a messy wind. There’s no push, no power, nothing to get excited about. A few cross-onshore breezes will just chop up what little is there. You’d be better off sorting your gear or checking the tide pools. There’s a good week of nothing here, so don’t hold your breath.
Then, on the morning of Thursday the 3rd, things suddenly wake up. A solid SW groundswell pushes through at 10ft, but the period is only a middling 8 seconds. The combined energy jumps to a strong 866, so there’s plenty of water moving, but it’s a messy, lumpy beast with a fresh cross-onshore wind. It’s got some size for sure, but for a beach break, this looks more like a battle than a pleasure. Honestly, with that much swell and wind, it might be more interesting for the kite crew than us paddle surfers.
That swell backs down a bit into Friday the 4th. The morning is still onshore and junky, but the afternoon shows a little promise. We get a 5ft SW swell with a light cross-offshore breeze. It’s the first time the conditions actually turn clean. The energy is moderate (175), and for a brief window, it looks like there’s something to ride. This is about as good as it gets in this outlook, and it’s not saying much. Still, it’s the most legit window we have.
After that, it’s a slow fade into small, messy surf and building winds. The weekend and the following week sees the size drop off to less than 3ft, with strong breezes and onshore slop. By the 7th, we’ve got a gale-force SSW wind blowing straight on, but the swell is only a foot and a half. That’s just a mess.
The long-range stuff from the 8th onward is a dead loss. Tiny, weak swells with the odd clean moment but no size. There’s nothing surfable on offer. It’s a classic case of a blank run for Rhosneigr. It feels stuck in a rut, but that’s the nature of the place sometimes.
So, there you have it. Not a classic. The only real chance is that Friday afternoon on the 4th of September. Don’t go booking time off work for the rest of it.

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.
