The Lowdown

Alright, folks, Rusty here. Let's be straight with you. I've stared at the charts for the next couple of weeks, and for Rhos-On-Sea, it's a pretty grim picture. We're looking at a real dry spell for any kind of proper surf. The first week is essentially a write-off, with flat conditions and poor surf quality. There's a glimmer of something small around the 15th and 16th, but it's nothing to get excited about. We then go into another long flat patch that stretches through to the end of the forecast period. Honestly, it's one of those times where you might be better off checking the sandcastles than trying to get wet.

Let's break it down, day by day. The whole first week, from the 9th through the 14th, is pretty much flat. We're talking about a few tiny, weak waves that barely break, mostly with short, crumbly periods. The wind is mostly light, and we get some glassy moments on the morning of the 12th and 13th, but there's just no swell behind it. It's a total bust.

Now, around the 15th, we finally see a pulse of energy. It's a small NW groundswell, but it's short-period at 5 seconds, so it won't have any punch. The combined wave energy will bump up to a weak 49 (moderate) and 34, but the wave heights are only going to be in the 3ft to 3ft range. The wind is a cross-shore, which will keep it a bit messy. It's a "poor surf conditions" call, and it's honestly not worth the paddle. The 16th has less energy, weaker, onshore wind, and smaller waves. A short groundswell like this at a point break is still a better bet than a beach, but it's just not enough.

After that, we are back to a long stretch of nothing. From the 17th all the way through the 24th, the models show a big, fat zero for wave height and energy. It's just flat, with a lot of glassy mornings that will be pure torture to look at. The 19th shows a tiny blip of energy from another NW groundswell, but the period is a meager 4 seconds, and the waves will barely be a ripple. The water is warmer than usual for this time of year, a notable 65°F on the 9th, but that's not much comfort when there's nothing to surf.

So, there you have it. A long, blank run. For this area, that can be normal, but it won't stay poor forever. Forecasts can change. But as it stands right now, there are no good surf options in the 16-day window. Keep the board in the car, but maybe just for the drive to get a coffee.

Rusty, signing off.

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.
