The Lowdown
Alright, let’s cut through it. The outlook for Rhos-On-Sea is pretty bleak over the full 16 days. There’s a long, empty stretch right from the start with nothing to surf until the 16th. From now through the morning of the 16th, it’s all poor conditions or flat water.
On the morning of Wednesday the 16th, we finally see something – a 1.6m swell from the NW, but the period is a dumpy 6 seconds. The combined energy reads 155 (moderate), but the wind is a side-shore 25 km/h, creating a rough cross-chop. That’s more of a kite day than a paddle day. By afternoon, the swell drops to 1.3m and the wind eases to 20 km/h from the west, which cleans it up, but the swell is small and weak.
From Thursday the 17th through the 21st, it’s flat again. A tiny blip on the 20th gives 0.5m from the north with a 4-second period – not worth mentioning beyond this. The rest of the run, right through to the 27th, stays flat and clean but completely waveless.
For this break, that’s just how it goes. Rhos-On-Sea is an inconsistent point break, and when there’s no swell, there’s no swell. Not a single standout session in this window. Don’t hold your breath.

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.
