Alright, Rusty here. Let’s have a look at what’s cookin’.
To be straight with you, the next couple of weeks are a real struggle. We’ve got a long dry spell staring us in the face. From now, right through until at least the morning of Saturday the 19th of July, there’s nothing worth paddling out for at Rhos-On-Sea. That’s over a week of flat to near-flat, onshore junk with barely a ripple of energy – the combined energy tops out at a measly `25` on the Sunday afternoon of the 12th, but even then the wind is straight onshore and messy. Total write-off for a surfer.
Honestly, this is one of those spells where the ocean just shuts down. Feels like the whole place is holding its breath. Not a single wave in that first week and a half is even close to being rideable. If you’re a kite surfer, some of those choppy onshore days might give you something to play with, but for a paddle surfer, leave the board at home.
We finally see a flicker of life on the morning of Sunday the 19th. A little pulse of swell shows up, `2 ft` from the N, but the wind is onshore from the ENE at `6 mph` – not clean, not really surfable. The combined energy is only `15`. Monday the 20th is the first time we get something a bit cleaner: the morning is light cross-shore from the NW, but the swell is tiny at `1 ft` from the NW. By Monday afternoon, the wind shifts to a light cross-off from the NW and it goes clean, but again, `1 ft` is barely a ripple – combined energy of `3`. Not a session, just a bit of hope.
Tuesday the 21st is more of the same: tiny `1 ft` NW swell with light cross-onshore breeze. Clean enough to look at, but not enough push to stand up on.
That’s about it. The rest of the window after the 21st is mostly flat again, with a few glassy mornings but zero swell. The water temp is sitting at `65°F`, which is a massive `7°F` warmer than normal for this time of year – that’s very unusual. Feels like a bath, but there’s no wave to enjoy it with.
So the honest truth, mate – there is no standout. There is no best day. The whole 16-day forecast is one long gap of poor to no surf. If you are desperate, the cleanest and least ugly moment is probably the afternoon of Monday the 20th of July, but you’d be floating around on ankle-biters. Better to wait for the next system to roll in.
Stay patient. 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.
