The Lowdown
Right, well, I’m looking at the charts for the next 16 days here at Rhos-On-Sea, and I’ve got to be straight with you—it’s looking pretty bleak. This is a stretch of weather that’s not giving us much to work with. The water’s sitting at 66°F which is a solid 8°F warmer than usual for this time of year, which is very unusual, but that’s where the good news ends.
The first real sniff of anything rideable doesn’t show up until Saturday morning, the 18th of July. That’s a few days of flat, choppy nothingness to get through first. On Saturday the 18th, we’ll see a tiny pulse of 2ft swell from the northwest, with a period of 5 seconds. The combined energy is weak (19). The wind will be a light cross-offshore from the WNW, which will keep it clean. It’s inconsistent and tiny, so it’s barely a paddle.
Then on Sunday the 19th, things get a little more interesting. The morning is looking glassy with a light WNW wind and the same small NW swell, around 2ft, period 5 seconds. The energy is still low (11), but if you’re desperate for a longboard session, that glassy morning window is your best bet. It’s still poor surf conditions, but at least it’s clean.
The rest of the week is a write-off until the 23rd of July. Thursday the 23rd shows a slight bump: 3ft from the ENE in the morning, period 4 seconds, and glassy conditions. The energy is still weak (20), but it’s the best looking wave height in the whole run. The wind is glassy, so it’ll be clean, but it’s a short period windswell. The afternoon picks up a little to 3ft, but the wind goes cross-onshore and it gets choppy.
Friday the 24th is clean again with a light cross-offshore wind, but the swell is dropping back to 2ft by morning and 1ft in the afternoon.
After that, it’s pretty much flat again until the 27th of July, where we get a few 1ft glassy or clean windows, but the energy is minimal (7). Honestly, there’s no standout session here. The best of a bad bunch is the glassy Sunday morning on the 19th, or the glassy Thursday morning on the 23rd if you just want to get wet. Crowds are likely to be low because there’s just nothing to surf for the most part.

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.
