The Lowdown

Alright folks, Rusty here. Let’s be straight with you. Looking at the next couple of weeks, it’s a real tale of two cities, and by that, I mean it’s mostly flat and gutless, with a couple of brief pulses of energy that might get the heart rate up, but they’re buried under messy winds. The long-range stuff is more of a “keep an eye on it” than a “rip the cover off the board” situation.

Right out of the gate, forget about it. The first week is a total write-off. We’re looking at tiny, short-period slop for days on end. The swell’s barely a ripple, and the winds are all over the shop, mostly cross or onshore, kicking up chop. There’s a brief moment on Monday the 10th with a clean cross-offshore breeze, but there’s no swell behind it to make it worth your while. It’s a classic “check the cam, decide it’s not worth the sand in your wetsuit” kind of a run. The water is sitting at 63°, which is a touch warmer than normal for this time of year, so at least you won’t freeze while you’re staring at the flatness.

The first real pulse of anything shows up on the 17th, a Monday. We get a bump of swell, maybe 3ft, out of the WNW with a short, 4-second period. That’s steep, crumbly, and weak. The wind is a cross-offshore, which will keep the surface clean, but the energy is just not there. It’s the kind of day where you might get a few knee-to-waist-high sliders if you’re super keen, but it’s not going to be pretty. The energy rating is weak, sitting at 20, so don’t expect any punch.

The second pulse, and the only thing that even comes close to a standout, is on the 21st and 22nd. By the 21st, we see a jump in size to 3ft out of the NW with a period of 5 seconds. But, and it’s a big but, the wind is a fresh cross-shore at 19 mph, which is going to make it lumpy and hard to read. The energy is still only moderate at 63. Then on the 22nd, it gets a bit bigger, up to 4ft, but the wind absolutely howls from the west at 25 mph, making it a strong cross-onshore mess. This isn't a surf forecast; it’s a kite-surfing forecast. The energy is slightly higher at 76, but it's all going to be blown flat and choppy. If you’re on a twintip, this might be fun, but for a paddle surfer, it’s a skip.

After that, it just fades back into the grey. The long-period swell we see sneaking in on the 23rd, with a 14-second interval, is a tease, but it's only 0.3ft. There’s no power behind it. It’s just a ghost of a swell, a promise of winter that’s still a long way off.

So, the long and short of it is: don’t get your hopes up. There are no diamonds in this rough. The 21st and 22nd are the only days with any size, but the wind is going to wreck it. It’s a two-week period where the beach is more for a walk than a paddle. The conditions are so consistently poor that it’s hard to see the surf turning on quickly. A blank run like this can happen here. We just gotta wait for the next low-pressure system to get its act together.

Rusty out.

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.
