The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Rhos-On-Sea over the next couple of weeks.
Honestly, if you’re lookin’ for a proper surf session, you’re gonna be waiting a while. The first ten days or so are a real write-off. We’re lookin’ at a solid gap from now through the 10th of August with barely a ripple to speak of. The swell energy is all but dead – we’re talkin’ values of 0 to 4 most days, with some tiny 0.3ft to 1ft windswell pulses that just don’t have the guts. The wind's all over the place too, mostly cross-shore or cross-onshore, sometimes light offshore but without any swell to work with, it’s just a flat, clean lake.
You get a little tease on the morning of Tuesday the 11th of August. The swell finally starts to show, with a 5ft NW groundswell (period 6 seconds) pushin’ through. The combined energy bumps up to a moderate 133, and the wind goes glassy calm. That’s the one moment in the whole outlook where it’s not completely hopeless. It’s a small, short-period NW swell, so it’ll be a bit weak and maybe a little crumbly on the face, but if you’re desperate for a paddle and a few grovelly ones, that’s your window. It’s a point break here, so it might line up okay for a few walls. The water temp ain’t mentioned for this break, but given the lack of anomaly data, it’s about what you’d expect for the time of year.
After that glassy morning, the wind swings cross-onshore in the afternoon and the energy drops back to 119, and then we’re back to small stuff through the 12th and 13th. The 13th of August finishes the run with no swell at all.
Bottom line: the only half-decent chance in this 16-day window is that Tuesday morning, the 11th of August. Keep your expectations real low – it’s not a standout by any stretch, just the least bad option on the board.
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.
