The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking for Rhosneigr over the next couple of weeks.
To be straight with you, it’s a grim start. We’re looking at a big fat blank from now until Friday the 28th of August. For nearly five days, there is simply nothing worth paddling out for. Tiny, weak dribble with onshore breezes – leave the board at home.
Friday the 28th finally shows a bit of life, but it’s a struggle. We get a morning of waist-high, 4ft swell from the SSW, but it’s coming in with a cross-onshore wind. The combined energy is moderate (228), but it’s only a marginal call and not something to get excited about. That afternoon, the wind swings onshore and it’s back to rubbish.
The weekend (29th-31st) is a write-off. More onshore winds, more rain, and some seriously blown-out conditions. On Sunday the 30th, we’ve got a near gale from the SSW hitting 31 mph – that’s kite-surfing weather, not paddle-surfing. Skip it.
We get a bit of a breather into early September, but still nothing surfable until Wednesday the 2nd of September. That morning, a 7ft SSW swell hits, but with a fresh cross-onshore wind at 19 mph. The combined energy is strong (400), but the poor quality means it’s a messy, lumpy mess. Only for the experienced crew who don’t mind some wind-chop.
Thursday the 3rd of September offers a bit more hope. We’ve got a solid 7ft to 7ft W and WNW groundswell, with the combined energy reaching up to 308 (moderate to strong). The morning has a light onshore wind, making it a marginal call but worth a look for bigger-wave hunters. This is one of the better options on offer, but with onshore winds, it won’t be clean.
After that, things fade fast. The rest of the forecast drops back to tiny waves and clean but weak conditions – good for a longboard cruise if you’re desperate, but nothing that’s going to light your fire.
Honestly, across the whole 16-day window, the standout window is Thursday the 3rd of September morning. It’s the biggest push of swell from the W, but keep your expectations in check because the wind isn’t doing us any favours. For a clean, lined-up wave, we just don’t have it this time.
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.
