Alright folks, Rusty here with a look at the Rhos-On-Sea forecast. Right off the bat, I gotta be straight with you – this 16-day window is looking pretty grim. There's a huge gap of flat, useless conditions stretching from today right through most of the period. Seriously, we're looking at over a week of nothing but small, choppy leftovers or total flatness.
The very first hint of anything worth paddling out for doesn't show up until the morning of Sunday the 19th of July. And even then, it's not exactly a world-beater. We'll finally see some swell from the NNW, pushing about 6ft. The energy's moderate, sitting at 209, but the period is a short 6 seconds, so it'll be a bit lumpy and lacking that proper push. The wind does swing cross-offshore though, which is a major plus. That light WNW breeze should clean things up nicely, making it rideable. But honestly, for a point break, the swell direction isn't ideal, so don't expect perfection. The water temp is sitting at 64°, and that's a whopping 6° warmer than normal for this time of year – that's very unusual, you won't need a thick suit, that's for sure.
After that little blip, the energy drops back sharply on Monday the 20th with a knee-high NW swell and then it fades right back to flat again for the rest of the period. If you're desperate for a paddle, Sunday the 19th is the only show in town. Other than that, the whole forecast is a bust. I'd hang the board up for a bit and check back later. Forecasts change, and it never stays this dead for long around here. Rusty out.

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.
