The Lowdown
Alright folks, Rusty here. Let’s be straight with you about Rhosneigr. Looking at the whole 16-day window, I’ve got to be honest—it’s looking bleak. The finder is pulling up a zero for most of the run, and the guidance confirms it’s a beginner-friendly spot that’s fairly consistent, but not this time around. There’s a long, dry gap from now until Friday the 18th of September, with nothing but poor surf conditions and lumpy, cross-onshore wind messing things up. It’s not a total surprise for the area when the wind locks in from the wrong direction, but it’s still a gut punch.
We’ve got a touch of hope on the horizon, but you’ve got to wait for it. The only real standout in this whole forecast is Friday morning, 18th September. The wind finally swings offshore from the ENE at 12 mph, and the swell is 6 ft from the WNW. The period is a short 6 seconds, so it’s windswell, not a groundswell, but with that offshore wind cleaning it up, the “moderate offshore and clean” description is a welcome change. The combined energy is moderate at 222, so it’s got some push. The water temp is a touch warmer than normal for this time of year, which is a nice bonus. For a beginner spot, 6 ft is on the upper edge, so it might be a little challenging for absolute beginners, but good for those who’ve got their pop-up dialed. This is the only session worth timing.
Other than that, there’s a whisper of clean conditions on the afternoon of Thursday, 17th September, with a light NNE breeze at 3 mph and a cross-off wind, but the swell is only 3 ft. It’s small and clean, but barely surfable.
For the rest of the run, it’s a write-off. Strong winds, cross-on conditions, and lumpy, messy surf. The waves are either too small or too blown out. Don’t bother paddling out until that Friday the 18th. If you’re desperate for a fix on a kite, the 5 ft to 7 ft days with strong cross-onshore winds earlier in the run might be more interesting for a kite surfer than a paddle surfer.
Stay patient, and check back—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.
