The Lowdown
Alright folks, Rusty here. Let’s have a look at the next 16 days for your local stretch.
Right off the bat, I’ve got to be straight with you: this is a tough one. The first week and a half is basically a write-off. We’ve got a couple of pulses of swell, up to about 5 feet, coming in from the SSW and SW, but the wind is a mess. It’s cross-on or onshore with a moderate to fresh breeze for most of it, so the surf is gonna be lumpy, choppy, and pretty ordinary. The combined wave energy never gets past the moderate range, topping out at 195 on Wednesday the 2nd of September, but it’s all blown to bits. For a beginner spot like Rhosneigr, these conditions just aren't fun. Honestly, with the wind and the quality, it looks more like a kiteboarding session than a paddle session during that first week.
We’ve got a real dry spell from the 11th of September all the way through to the 15th. The swell just drops right off – we're talking ankle-snappers with combined energy barely hitting double digits. Clean, sure, but there’s nothing to ride.
Then, finally, a glimmer of hope. The morning of Thursday the 17th of September is the one standout. We’ve got a clean 5ft swell from the southwest, period of 6 seconds, and the wind is light and cross-offshore from the NNW. The combined energy jumps up to 142 (moderate), and the conditions are described as clean. It’s not a world-beater, but compared to the rest of the run, it’s the best we’ve got. The water temp is about average for the time of year.
So, you’re looking at a long wait. The first week is a washout with poor wind, then a full week of flat calm, before a single bright window on the 17th. Keep your eyes on that one, but remember, it’s a long way off, so forecasts can change.

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.
