The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Rhos-On-Sea over the next couple of weeks.
Alright, I’m gonna be straight with you—this is a tough one. The forecast is pretty bare for a long stretch. We’re staring down a big gap with no real surf to speak of. From now until the morning of Sunday, August 9th, there’s nothing ridable. That’s a solid five days of flatness. The water is sitting at 65°, which is a good 5° warmer than usual for this time of year—so at least the swim will be pleasant if you’re keen for a dip.
Sunday the 9th is the first whisper of life. The morning offers a tiny bit of swell from the NW at 1 ft, but with a period of only 3 seconds, it’s just wind chop. The combined energy is a measly 4 (weak). It’s not worth paddling out for. The pattern of poor conditions just keeps rolling through the week. You’ll see some glassy moments on the 11th and 13th, but with no swell to match, it’s a flat calm.
The best of the very limited options comes around Saturday, August 15th. In the afternoon, we get a little 2 ft NW swell, with a period of 4 seconds. The wind swings offshore from the SSW at 9 mph, which will clean things up nicely. The combined energy is still only 12 (weak), but it’s the closest we get to a surfable wave. This is a point break that’s inconsistent, so don’t expect much. It’s a beginner-friendly size, but the short period means the waves will be a bit crumbly.
Honestly, if you’re desperate for a paddle, that Saturday afternoon is your only real shot. Otherwise, the whole 16-day window looks like a write-off. The swell just doesn’t show up. For a spot like this, a blank run like this is not unusual, but it’s still a bummer.
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.
