Alright, let’s get stuck in. Rusty here, looking over the cards for this neck of the woods over the next couple of weeks.
Alright, so I’ll be straight with you—this is one of those outlooks where you might as well leave the board in the van for a good long while. The whole 16-day run is looking flat and pretty miserable. There’s a massive gap of absolutely nothing worth paddling out for. After a tiny bit of tiny, weak dribble right at the start, it goes dead quiet for the better part of a week. Then from around Wednesday the 16th of July, we get a tiny pulse, but it’s still gutless. There are no standouts. Not a single day is worth calling a session.
The only shred of surf we see is on Saturday the 4th of July at Rhosneigr. It’s exposed to the SW, and the swell is coming from that direction, so the setup is right. But it’s a poor 4 ft on a short 5-second period, with a combined energy of just 52 – that’s weak. On top of that, you’ve got a fresh 19 mph onshore wind from the SW, making it a choppy, blown-out mess. Water temp is 61°, which is a touch warmer than normal for the time of year. Honestly, it’s a write-off.
After Saturday the 4th, the swell completely dies. The next few days offer nothing but flat calm or tiny wind chop. From Thursday the 9th to Sunday the 12th, we get a few clean pockets with offshore or cross-off winds, but with zero swell and zero energy, there’s nothing to ride. That’s a four-day blank stretch right there.
The pattern tries to wake up again around Wednesday the 15th of July, but it’s still just ankle-slappers. By Thursday the 17th, we see a bit more energy – 2 ft from the SSW with a 6-second period and combined energy up to 59 – but it’s still onshore or cross-onshore, and frankly, it’s not worth the paddle. For a beach break like Rhosneigr, this kind of weak, short-period, onshore wind setup is more interesting for a kite surfer than a paddle surfer.
So, bottom line: if you’re desperate to get wet, maybe the slightest chance on Saturday the 4th, but you’ll be battling a strong onshore breeze for a tiny, weak wave. Otherwise, the next two weeks are a flat spell. It tends not to stay this way forever, but for now, the forecast looks about as exciting as a flat tyre. Keep the board in the bag and wait for the next proper swell.

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.
