The Lowdown
Alright, folks, Rusty here. Let’s talk about what’s cookin’ at Rhosneigr.
Right off the bat, I gotta be straight with you – this is a tough stretch. We’re looking at a 16-day window that starts with a whole lot of nothing. The first week is basically a write-off for any decent surf. From Monday the 20th right through to Thursday the 23rd, the ocean is flat, dead, and not worth a second glance. The wind is mostly cross-offshore, but with no swell to speak of, it’s just a waste of a good breeze. The water is sitting at 63°F which is a touch warmer than normal for this time of year, but that’s about the only positive.
We finally see a pulse of life on the morning of Friday the 24th, but it’s a sad little 1ft of swell from the WNW with a period of just 3 seconds – that’s all windswell and no push. The wind is cross-onshore and it’s choppy. Don’t bother. The afternoon gets even worse, dropping to 0.3ft from the south with a longer 13-second period, but with no size and onshore wind, it’s a tease.
The weekend of the 25th and 26th brings a bit more energy, but it’s still messy. Saturday morning sees 1ft from the SW with a 3-second period and a fresh onshore breeze at 19 mph. The afternoon picks up to 4ft from the SW at 5 seconds, with the combined energy hitting 70 (moderate wave energy), but the wind is straight onshore. It’s gonna be a bumpy, blown-out mess. Sunday is a slight improvement with cleaner conditions, but the swell is tiny again at 1.0ft and 0.3ft. Not worth the drive.
The second week doesn’t offer much hope either. There’s a bit of a pulse on Tuesday the 29th, with 3ft from the NW and a 5-second period, energy at 52 (moderate), but the wind is a fresh 19 mph cross-shore, making it lumpy. The afternoon cleans up with a cross-offshore breeze, but the swell drops to 2ft.
The best of a bad bunch looks like Friday the 31st of July. The morning has 2ft from the SW with a 4-second period, but it’s onshore with light rain. The afternoon is a total nothing with 0.7ft. Honestly, there’s no standout session here. The waves are small, the periods are short, and the wind is rarely working in our favour.
Look, if you’re desperate, the afternoon of Tuesday the 29th with clean cross-offshore wind and 2ft might be the least worst option, but it’s gutless. For the rest of the run into the first week of August, we’re looking at more of the same – tiny swell, poor periods, and inconsistent conditions. The pattern is clear: you’re better off finding something else to do.
Rusty, signing out.

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.
