The Lowdown
Alright, the surf forecast for Rhos-On-Sea is looking pretty grim, to be honest. We’ve got a real flat spell on the horizon, and it’s going to be a long wait for anything even remotely rideable.
Right off the bat, the whole first week and a bit is a washout. From Monday the 27th of July right through to the end of the month, there’s just nothing. The wave energy is at zero (0) for nine straight records, with poor surf conditions all the way. The wind is mostly offshore or cross-offshore, which would be great if there was any swell, but there just isn’t. It’s a proper flat spell.
We finally get a tiny pulse of life on the morning of Friday the 31st of July. It’s a weak little 1ft wave from the N, with a short period of 4 seconds. The combined energy is barely a whisper (5). It’s still listed as poor surf, so don’t get your hopes up. The wind stays cross-offshore from the WNW, so at least it’ll be clean. But honestly, that’s a knee-high dribble, not a wave you’d paddle out for.
The next few days are more of the same – tiny, weak energy readings in the single digits (2, 1, then 0 again). The surf is flat again through the 2nd of August.
Now, there is a glimmer on Monday the 3rd of August. We get a clean 1ft wave from the NNW in the morning, combined energy of 7, and the wind is glassy (0 mph from the SSE). That’s the best we’re going to see. Then Tuesday the 4th of August morning is another glassy one, with a 2ft wave from the E, energy of 8. This is the best on offer. It’s still tiny, but for a point break like Rhos-On-Sea, that tiny, clean, glassy wave could be a fun little longboard session. The break is inconsistent, so the sets will be few and far between, but it’ll be clean.
For the rest of the forecast, from the 5th of August onwards, we see a few more mornings with a little 2ft to 2ft wave and light offshore winds, but the energy is still weak (6-7). Then it drops back to zero energy again from the 6th all the way through to the 11th of August. The last record on the 11th shows a fresh cross-onshore wind of 22 mph with a lumpy surface, which is basically a write-off.
So, the standout here is the glassy morning of Monday the 3rd of August. If you’ve got a longboard and can get out for a quiet, clean paddle, that’s your window. The Tuesday morning is a similar backup. Otherwise, it’s a long stretch of flatness. Don’t get too worked up about it, the forecasts can change, but for now, it’s a real bust.

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.
Rhos-On-Sea is 2 km (1 miles) from Colwyn Bay. If you plan a holiday in North Wales, look for hotels and other accommodation in Colwyn Bay. Colwyn Bay has rooms for a wide range of budgets as well as car hire and transport links.
