The Lowdown

Alright folks, Rusty here. Let’s be straight with you. The next two weeks are looking pretty flat and grim for Rhosneigr. We’ve got a long stretch of nothing on the cards, so if you’re itching to paddle out, you might want to find another hobby for a bit.

The first real glimmer of anything shows up on Wednesday the 20th. We’ve got a new swell filling in, with waves around 4ft but from the WNW, which isn't ideal for this spot. The energy is weak to moderate at best, coming in at 105 units. Add a cross-shore wind to that, and it’s going to be a messy, lumpy day. Honestly, it looks more like a day for the windsurfers than for us on the paddleboards. The swell direction isn't matching up well and the period is a short 5 seconds, so it will lack any punch.

The bigger push comes at the end of the window, on Saturday the 23rd. The swell builds through the day, starting at 4ft in the morning and kicking up to 6ft by the afternoon. The energy jumps to a solid 215, showing there’s some power behind it, but again, it’s a short-period swell from the SSW. The winds are onshore and howling at 15-16 mph, so the surface is going to be blown out and choppy. It’s not going to be clean, and it might be too much for the beginners. For the more experienced crew, it’s still not going to be great. The whole run is just a series of poor surf conditions, with almost no clean windows of note.

The water temp is a touch warmer than normal at 63°F, sitting about 3°F above average, which is a bit of a surprise given the lack of swell. But that won’t help the waves.

So, bottom line: the swell window is a bust. We have a long, flat spell until the 20th, then a couple of days of junky, short-period windswell that won't offer much quality. There's not a single standout day in there, and the only real “surf” looks like it’ll be a battle against the wind. If you’re desperate, maybe watch the forecast for a change, but I wouldn’t hold my breath. This is one of those times when being a surfer in this area means being patient.

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.
