The Lowdown
G'day, it's Rusty here. Right, let's have a look at what's happening around Rhosneigr.
We are staring down the barrel of a pretty grim 16 days. The honest truth is, there is nothing in this forecast that even comes close to being a proper surf. For the first ten days straight, it’s all "poor surf conditions" with zeros across the board. That’s a long, dry spell.
Finally, on Sunday the 20th of September, the morning session shows a glimmer of something, but it's barely a pulse. We get a 4ft WNW groundswell with a period of 6 seconds and a combined wave energy of just 112 (moderate). The wind is light and cross-offshore from the NNW, which will make it clean. For a spot that’s exposed to the SW and usually needs a good push, this is more of a novelty wave than a proper session. It’s surfable, but it's very ordinary.
After that, it falls apart again. The rest of the forecast is a write-off, with more onshore winds and tiny swell. The truth is plain as day: for the next couple of weeks, your best bet is to leave the boards in the van or find something else to do. With no decent consistency and almost all the swell being blown out or just too small, it's a flat patch that you just have to ride out.
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.
