Alright folks, Rusty here. Gotta be straight with you – looking at Rhos-On-Sea over the next couple of weeks, and it's a quiet one. There's no surf to speak of for a solid stretch, so we're in for a long wait. The first sign of anything rideable doesn't show up until Friday the 10th of July, but even then it's tiny and messy. We’ve got a full five days of flat calm or near-enough conditions to get through before that.
The water temperature is sitting at 63°, which is a massive 5° warmer than usual for this time of year – that's very unusual, like wearing a shortie in July when you'd normally be in a full suit.
Alright, let's break down the meager offerings. Friday the 10th of July morning sees a tiny 0.3ft ripple from the NW, with the combined swell energy a weak (2). The wind is cross-onshore, so forget it. By the afternoon, there's a slight pulse to 2ft from the NNE, but the period is a short 3 seconds, and it's crossed up. Still a hard pass.
Saturday the 11th of July morning is more of the same – 2ft from the NE at 4 seconds, but light cross-shore winds keep it choppy. The afternoon cleans up a bit with a cross-offshore breeze, and the swell nudges up to 3ft from the NNW, but it's weak (19). It’s surfable, but only just.
Sunday the 12th of July through Tuesday the 14th keeps us in the 2ft to 2ft range, mostly from the N or NNE. Periods are short, between 4 and 5 seconds, and the winds are a mix of cross and cross-on. It’s not worth getting excited about.
After that, it drops back down to near-flat from Wednesday the 15th of July through the end of the outlook. The wind stays clean at times, but there's just no energy.
Honestly, this is a blank run that's more typical for the area. It’s a waiting game. Keep your eyes on the charts, because it doesn't stay this poor forever.
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.
