The Lowdown
Alright folks, Rusty here. Let's be straight with you – this stretch we're looking at is a bit of a flat spell for our shores. I've scanned the full 16-day window, and honestly, there's nothing that gets the heart racing. We've got a long stretch with no real surf on offer, so if you're desperate for a paddle, you're going to be fighting for scraps.
The water's sitting at about 63°, which is a touch warmer than usual for this time of year, so that’s a small silver lining. But the waves? They're just not cooperating. For the first week and a half, we're looking at tiny, weak swells with a lot of onshore wind. It's going to be lumpy and messy out there. From the 5th through the 12th, we're seeing swell heights mostly under three feet, with periods all over the place, but no real energy behind them. The winds are all over the compass, but mostly cross-onshore, which just chops everything up.
Things get a little more promising around the 13th and 14th, when the swell tries to bump up a bit. On Thursday the 13th, we see a swell around 4ft, but it's still coming with a short, weak period and a cross-onshore wind. The same goes for Friday the 14th. It's just not clean. There's a bit of energy in the water on the morning of Thursday the 14th, but it's still coming from the west-northwest with a cross-onshore wind. This isn’t the conditions to be getting excited about.
The only time things look like they might clean up is the morning of Sunday the 16th. We get a bit of a cross-offshore wind from the north, and it's clean. But the swell is only around 4ft with a short 6-second period, which will be mushy and disorganized. It might be the best of a bad bunch, but it's a low bar.
Honestly, if you're looking for a recommendation, I don't have one. The whole window is a write-off for proper surfing. There’s a long stretch with nothing, and the few pulses of slightly bigger swell are accompanied by poor conditions. The beach setup will just be a mess of closeouts if we get any of that wind against the current. It might be more interesting for the kite-surfing crew than for us on a paddleboard. Keep your board in the car and your expectations low. We're in a poor stretch, but it won't stay this way forever – forecasts can change.
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.
