The Lowdown
Alright, folks, Rusty here. I’m looking at the next 16 days for Rhos-On-Sea, and I’ve got to be straight with you – it’s a rough stretch. The data shows a whole lot of nothing for the first week, with hardly any swell showing up. We’ve got a long gap of over a week where the wave energy is basically zero. The water is sitting at 66° – that’s much warmer than normal for this time of year, which is a weird bonus, but it doesn’t help the surf.
The first real glimmer of something surfable is on Monday, July 20th. Afternoon, we’ve got a tiny NW swell at 2 ft, with a short period of 5 seconds. The wind is cross-off from the WNW at 6 mph, so the surface will be clean. The combined energy is weak (14). It’s small and inconsistent, typical for Rhos-On-Sea, but it’s the best on offer for the opening days. The swell direction is dead on the optimum for this point break, so there’s a little hope.
The next session to look at is Tuesday morning, July 21st. Still small, still 2 ft from the NW, but the wind goes light and cross from the NW at 3 mph. The surface will be glassy with just small ripples – that’s a major positive for clean waves. The energy is still weak (16). It’s not going to be a classic, but with the wind so light, you might snag a few fun ones if you’re patient.
Wednesday morning, July 22nd sees a tiny bump. Swell height hits 3 ft from the NW, period at 6 seconds. The combined energy comes up to 60 – still weak, but it’s the most energy we’ll see for a while. Wind is light and cross from the NW at 6 mph. This is probably the pick of the first week, but it’s still a far cry from good.
After that, it drops off a cliff. From Thursday, July 24th all the way through to Friday, July 31st, the wave heights are mostly zero or below 2 ft, with energy readings of 6 or less. Absolute flat spell. The wind is clean or offshore on some days, but there’s simply no swell to push.
We finally get another pulse on Monday, August 3rd. Morning brings a 2 ft NW swell, 3-second period, with a cross-off breeze from the WSW at 16 mph. The energy is a measly 5. The wind is strong, which will make it bumpy, but it’s at least something moving. The true standout (if you can call it that) is the Monday morning of July 22nd – that 3 ft with the light wind is the best we’ve got.
Overall, this is a tough outlook. The point breaks at Rhos-On-Sea are inconsistent at the best of times, and this stretch confirms it. There’s nothing for beginners here, as the tiny swell is too weak to learn on, and the bigger stuff just isn’t showing up. The forecast for the second week is so barren it’s barely worth writing about. Keep your gear waxed, and hope the next window brings a real swell.
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.
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.
