The Lowdown
Alright folks, let me break down what’s happening. It’s a tough stretch coming up at Rhosneigr. We’ve got a real dry spell on our hands, the kind that makes you want to check the date on your wax. For over a week, from Wednesday morning the 26th of August all the way through to Friday morning the 4th of September, the surf is just not on. You’re looking at poor surf conditions day after day. The wave energy is weak, barely reaching triple digits at times, and when it does get a little push late August, the wind is just trash – strong cross-onshore or onshore, blowing it all to pieces. There’s a couple of pulses from the SSW, but the wind is a no-go.
The one little blip of hope comes on Friday the 4th of September in the morning. We finally get a light cross-offshore breeze from the NNW, cleaning things up a touch. The swell is small, coming from the SW at 4 ft, but with a period of only 5 seconds, it’s weak and disorganised. The combined energy is just 74, so it’s a “surfable but very ordinary” kind of session. A longboard might get a few, but don’t expect anything to write home about. After that, the window slams shut again. The forecast shows some crazy strong southerly winds and a massive jump in swell energy up to 1254 on Monday the 7th of September, but that’s a near gale cross-onshore with 10 ft of swell. That’s expert-only territory, and even then, it looks more like a kite-surfing day than a paddling one. The rest of the second week is a write-off with messy onshore wind and tiny waves. The water temp is about average for the time of year, nothing unusual.

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.
