The Lowdown
Right then, folks, Rusty here. Let’s have a look at what’s cookin’ for Rhosneigr over the next couple of weeks. I’ll be straight with you – it’s a grim outlook. We’re looking at a proper flat spell, so don’t bother waxing up just yet.
The first record kicks off on Friday the 17th of July, but it’s a total write-off. We’re talking tiny, knee-high dribble at 0.7ft from the SSW with a weak 6-second period. The combined wave energy is a paltry 7 (weak), and with a cross-off northerly breeze, it’s just not doing anything. The following days, right through to the 22nd of July, are even worse – mostly zeros on the energy scale. There’s a solid gap of almost a week with absolutely no surf to recommend.
We finally see a little bump on the 23rd of July, but it’s a 1ft windswell from the west with a period of just 3 seconds. That’s barely a ripple. The energy is still weak at 2. The wind is light and cross-shore, so it'd be clean, but there’s nothing to ride.
The only faint glimmer comes on the 24th of July, Friday morning. Swell picks up to 3ft from the WNW with a period of 5 seconds. The combined energy climbs to 33 (still weak). But the wind is a moderate cross-onshore from the west, making it choppy. It’s still poor surf. After that, it’s back to flat or near-flat conditions through the end of July and into the 1st of August.
The water temp is about average for the time of year, so no drama there, but it won’t help you when there’s no waves.
Honestly, there’s no standout here. Not a single day worth paddling out. If you’re desperate for a session, you’d be better off looking for a lake or taking up golf. The setup is so weak and small that even a kite would struggle to get going. It’s a classic blank run for the area – sometimes it just stays flat for weeks.
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.
