The Lowdown
Alright, folks, Rusty here. Let’s talk about Rhosneigr over the next 16 days.
I’ve got to be straight with you – this stretch is looking pretty flat. The finder is showing zero surfable waves for the whole period, from today (19 July) right through to 3 August. That’s a long dry spell for a spot that’s usually fairly consistent. For a beginner-friendly break like this, you’d normally expect something to ride, but the models are saying no.
The first few days, 19 and 20 July, have barely a ripple – 0.3 ft of south swell with a period around 10–11 seconds, but the wind is cross-off or cross, and the combined energy is tiny (2). Nothing to get excited about. Then from 21 July to 25 July, it’s almost completely flat – zero swell listed for most sessions, just a few 0.3 ft readings with weak energy (3–7) and onshore or cross-on winds. The 26th and 27th see a little bump: 3–3 ft from the SW on the 26th, but the period drops to 4–5 seconds – that’s short-period windswell, messy and lumpy with cross-on winds in the 15–19 mph range. Combined energy reaches 58 on the Sunday afternoon, but the surf quality is poor. The 31st of July gives a brief moment of offshore wind from the ENE, with 4 ft of SW swell but again only 4-second period – that’s a short, weak wave, and the energy is still only 45. Still poor.
There’s no standout. The whole 16-day window is a write-off for surf. The only slight hope might be the 31st afternoon if you’re desperate for a tiny, gutless wave, but honestly, I’d save the gas. Rhosneigr is known for being fairly consistent, so this kind of blank run is unusual, but it happens. Forecasts can change, but right now there’s nothing worth paddling out for.
Stay patient, and keep an eye on the charts. This is Rusty, signing off.

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.
