The Lowdown

Alright folks, it’s Rusty here. Let’s be straight with you—it’s been a flat, frustrating stretch for us. We’ve got a pretty grim 16-day window ahead, with nothing that’s gonna get the heart pumping. For the first few days, we’re looking at small, weak, short-period slop, and after that, it just dies off completely. A long stretch of nothing.

Wednesday morning kicks things off with the biggest, and quite frankly, the only real wave of the opening days. We’re talking 4.9ft of windswell out of the NW with a weak 6 second period. The energy reading is a feeble 159, and the northwest wind is chopping it all up. It might be surfable for the desperate, but it’s going to be a messy, bumpy battle. A cross-shore breeze isn't doing us any favors, and the water is notably warm at 64°, a good 4.5° above the norm for this time of year. The wave quality is just poor.

That’s pretty much the only pulse of any size. The rest of the forecast just flat-lines. We’ll see a tiny 2.9ft wave Wednesday afternoon, but the energy is completely gone at 42. After that, the ocean just turns off for days on end. Thursday through Tuesday is a complete blank for surf, just minimal bumps here and there that won’t break properly. The wind is light on Thursday morning with a glassy, clean look to the ocean, but there are no waves to clean up. Just a dead calm.

We get another tease of life on Tuesday, September 16th, with a pathetic 2.3ft NW windswell at 4 seconds and an energy of just 16. It’s more of a ripple than a wave. The spell of total flatness then sets in again for over a week. From the afternoon of the 16th all the way to the start of the 23rd, it's a desert. Nothing. Zero. The models occasionally show a clean offshore wind, but there’s simply no swell for it to work on.

Finally, on Wednesday the 23rd, we see a ghost of a wave—a 0.9ft easterly bump with a 3 second period, and an energy of just 1. That’s less a wave and more a change in the water’s surface. Honestly, at this point you’re better off fixing your fins or going for a paddle in a lake.

It’s a rough outlook, no doubt. The ocean’s just taken a full holiday. There’s nothing here for beginners, and nothing for the experts either. Forecasts can change, but as it stands, this looks like a blank run for the area. Keep the wax dry, and I’ll keep an eye on things.

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.
