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. I gotta be straight with you—this one’s a tough pill to swallow. The pattern is flat, real flat, and it’s gonna stay that way for a long stretch.
The first few days offer a tiny bit of life, but it’s not gonna get your heart racing. Wednesday morning the 22nd, we’ve got a weak NW windswell pushing in at about 3ft, coming from the NW with a short period of 6 seconds. The combined energy is a measly 36, so barely a ripple. The wind is light cross from the NW at 3 mph, so it’s not blown out, but the waves are just poor. You’d be lucky to find a knee-high lump. The water is sitting at 66°, which is a massive 7° warmer than normal for this time of year—very unusual, feels like a bathtub compared to what you’d expect. That afternoon, the swell drops to 2ft with even less period (5 seconds) and energy (17). Still poor.
Thursday the 23rd and Friday the 24th are more of the same—tiny NW swell, short period, and cross winds. The morning of the 24th sees a little 2ft NW swell with a 4-second period and energy of just 11, but the wind goes cross-offshore from the WNW at 6 mph, keeping it clean. Still, there’s nothing to ride.
Then from Saturday the 25th right through the end of the month and into early August, the wave heights drop to zero. We’re talking a solid 10-day stretch with absolutely no swell on the charts. The wind is offshore or clean at times, but without any waves, it’s just a flat, glassy lake out there. We get a couple of glassy mornings on the 30th and 31st, but still nothing moving.
You’ll have to wait until Monday the 3rd of August for a tiny, pathetic pulse—0.7ft from the ESE with a 2-second period. That’s not surf, that’s a ripple on a pond. The wind is glassy from the S at 3 mph, but it doesn’t matter.
So, the honest truth? There’s no standout here. Not a single day worth paddling out for. The entire 16-day window is a bust for Rhos-On-Sea. If you’re desperate for a splash, the best you’ll get is the morning of the 22nd or 23rd, but you’d need a longboard and a lot of patience. The swell is tiny, the period is short, and the energy is weak. For now, it’s a waiting game. Forecasts can change, but right now, this is as poor as it gets.
Stay tuned, but don’t hold your breath.

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.
