The Lowdown
Alright folks, Rusty here. Let’s have a look at the Rhos-On-Sea outlook for the next couple of weeks.
Straight up, I gotta be honest with you – this is a tough one. For the first week and a half, there’s just nothing happening. The forecast is a flat, empty lineup with zero wave energy. From Saturday the 5th all the way through to the evening of Wednesday the 16th of September, it’s a complete write-off. We’re looking at a solid 12-day gap with no surf to speak of. The wind’s gonna be a factor at times, with some offshore breezes, but without any swell, it’s all for nothing. You’ll see some glassy conditions on the 12th, 14th, and 15th, but it’s like a mirror out there – pretty to look at, but not a wave to ride.
The only faint glimmer comes on Saturday the 12th of September afternoon. We finally see a tiny pulse of swell from the NW at 3 ft, but with a period of just 5 seconds, that’s weak, short-period windswell. The combined energy is a paltry 52 (weak energy), and the wind is a light onshore from the NE. That’s not going to do anything for a point break like Rhos-On-Sea.
Things get a bit more interesting on the 16th. Wednesday the 16th of September sees some strong offshore winds from the SW, blowing at 15 to 22 mph, which would clean up the surface nicely. But again, the swell is completely absent. It’s like a washing machine with no water.
The best of a bad bunch, if you can even call it that, is Saturday the 19th of September. The morning brings a tiny 0.7 ft swell from the ESE with a period of 2 seconds – basically nothing. However, the afternoon session on the 19th is glassy, with a 0.7 ft swell from the E at 3 seconds. The combined energy is a measly 1 (weak energy). It’s still essentially flat, but the glassy conditions are the only real positive note in this entire outlook.
Honestly, for Rhos-On-Sea, this is a normal blank run. The point doesn’t always fire, and when the charts are this empty, you’re better off finding something else to do. There’s no standout, no hidden gem – just a long stretch of no surf. The forecasts can change, but right now, it’s a paddling pool.
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.
