The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the table for Rhosneigr over the next couple of weeks.

To be straight with you, the 16-day window is a real struggle. There’s almost nothing worth paddling out for. The water temperature is sitting at 64° which is a good 4° warmer than usual for this time of year, so at least you won’t be freezing your toes off while you stare at flat, messy water.

The first sniff of anything surfable comes on the morning of Saturday the 29th of August. We’ve got a little 3 ft SSW swell with a short 6-second period, but the wind is light cross-offshore from the ESE, so it’s clean. The combined energy is only 60 so it’s pretty weak, but it’s the best we’ve got for a while. Don’t expect much – it’s a beginner-friendly size but very ordinary.

After that, it’s a long run of poor conditions. Sunday the 30th through to the end of the first week is all cross-onshore choppy slop, with wind gusts up to 25 mph on Thursday the 3rd of September. The swell tries to pick up a bit around Wednesday the 2nd of September afternoon with a 5 ft SSW swell, but onshore winds and short period make it a mess. Thursday the 3rd sees the biggest swell of the forecast – 6 ft from the SW with a 6-second period – but with strong onshore winds, it’s just a lumpy, blown-out wall of white water. Combined energy hits 236 on Thursday morning and 313 on Thursday afternoon, but none of that matters with the wind howling.

The afternoon of Sunday the 6th of September has a marginal look – 6 ft SSW swell, 6-second period, and light cross-onshore breeze. The combined energy is 211, so there’s some push, but the conditions are only described as marginal. If you’re desperate, you might find a few lumpy ones, but it’s not pretty.

From Monday the 7th of September onward, it’s a dead zone. Swell drops right off, and by Thursday the 10th of September there’s zero swell with clean but empty water. The last few days of the second week are flat or close to it, with only the occasional light breeze on clean water. No surf to speak of.

So, the honest truth? There’s no standout day here. If I had to pick the least worst moment, it’s the Saturday morning of the 29th of August – that 3 ft SSW swell with light cross-offshore wind is the only window where you might get a clean, rideable wave. But it’s small, weak, and very ordinary. The rest of the outlook is a write-off. For a spot that’s fairly consistent, this is a tough run, but don’t lose hope – 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.
