Rhos-On-Sea surf forecast from 25 Jul 2026:
Best Forecast Surf Conditions for Rhos-On-Sea this week:
The largest open ocean swell (not directed at the beach) is 1.3m 5s period and expected on Sunday (Jul 26) at 4PM.
The Lowdown
Alright, Rusty here again. Let’s put it in feet and miles per hour. The outlook is grim, no two ways about it. There’s a massive gap of flatness right from the start, with the first real wave not showing up until the 1st of August.
Overall Pattern:
The ocean is doing a whole lot of nothing for the first week. The combined energy is zero for almost every session, which means no swell, no power. The wind is variable, but it’s a moot point. We get a tiny pulse on the 1st of August, but it’s weak as dishwater.
The Only Glimmer:
The only break on the cards is Rhos-On-Sea. It’s a point, and it’s inconsistent, needing a north-west swell to get going.
The only day with any height is Saturday, the 1st of August. The afternoon brings a tiny 1 ft swell from the NNW, with a pathetic period of 4 seconds. The combined energy is a pitiful 8 (weak energy). This is ankle-snappers. The wind is a light 6 mph cross-shore from the NW, which is clean, but there’s just no grunt behind it. It’s a longboard or a foamie day, if you’re that keen.
After that, it’s back to flat. The 2nd of August offers a 1 ft wave from the NNW with a 3-second period, and a 12 mph cross-shore wind that will chop it up. Then on the 8th of August, there’s a 0.3 ft ripple from the NW at 7 seconds, and a 0.7 ft one on the 9th of August from the N. The combined energies are 2 and 2 – you’re better off staying home.
The Verdict:
This is a long stretch of nothing. The water temp is about normal for the season, so that’s not a factor. But this kind of flat spell is normal for this area. The second week offers no hope. If you *have* to get wet, the 1st of August afternoon at Rhos-On-Sea might give you a tiny, clean bump, but honestly, don’t hold your breath.
Rusty.

Information about the Rhos-On-Sea Surf forecast
The above surf forecast table for Rhos-On-Sea provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rhos-On-Sea can be found by selecting the local surf guide option on the grey menu. Our Rhos-On-Sea 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 (Rhos-On-Sea) 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 Rhos-On-Sea 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.
