The Lowdown
Alright folks, Rusty here again, now in imperial. Lookin’ at Rhos-On-Sea for the next couple weeks.
Truth is, there’s nothing to get excited about. The finder’s a dud. No real surf options for a full 16-day window. That’s a long, lonely stretch.
Our only listed break is Rhos-On-Sea, a point break for intermediates. It’s inconsistent – rarely works. Favours a NW swell direction, but you wouldn’t know it from the charts. The water’s at about 64°F, which is about 4°F warmer than normal. Unseasonably warm, but no good with no waves.
From now right through until about the 22nd, we’re looking at flat to tiny conditions. The biggest puff comes on Wednesday afternoon, September 16th: a 4ft NW swell with a 5-second period – short period, no power. Combined energy is only 68, that’s weak. On Tuesday morning, September 22nd, you get a tiny 2ft NW swell, 4-second period, with offshore SW wind around 15 mph, so at least it’d be clean, but it’s barely a ripple.
There’s just no quality, no consistency. The wind is mostly cross-off or offshore, but without any real swell it’s academic. This is a kite surfer’s weather window, not a surfer’s.
A blank run like this is just part of the deal sometimes. Don’t force it. The ocean will come back around.
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.
