The Lowdown
Alright folks, let’s be real here. It’s looking flat and messy for the most part at Rhosneigr. The next couple of weeks are not shaping up to be a classic. Lots of small, onshore slop with no power behind it.
You’re looking at a long stretch of nothing through the 13th. Just small bumps and bumps of wind swell, most under 3 feet, and most with a crummy cross-onshore wind. The water is running about 62°F, which is a touch warmer than we’d expect, but that’s small comfort when there’s no waves.
The first time it might get interesting is on Friday the 14th. We see a small swell for the morning, around 4 feet, with a clean cross-offshore wind from the N. It’s not gonna win any awards, but it’s the first ridable surf we’ve seen. The energy is still weak, but it’s clean. Saturday the 15th looks similar, with a bit of WNW swell in the 3 to 4 foot range and clean conditions again in the afternoon. That’s your window if you’re desperate for a paddle.
After that, it looks like it’s fading right back out on the 16th and 17th. So, a big stretch of nothing, with a couple of small but clean days in the middle. It’s better than nothing, but it's not a week to plan your life around.

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.
