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.
Straight up, I’ve got to be honest with you – this is a tough one. The forecast is looking pretty grim. We’re staring down a long stretch of flat, unrideable conditions. The first real chance of anything surfable doesn’t show up until Saturday the 18th, and even then, it’s a real struggle. Between now and then, there’s just nothing doing. The swell is tiny, the energy is weak, and the whole setup is a non-starter.
The standout, if you can even call it that, is the morning of Saturday the 18th. We’ve got a bit of a pulse from the NW pushing in at 3 ft, with a period of 5 seconds. The combined energy is only 41, which is weak. The wind is a clean cross-off from the WNW at 9 mph, so it’ll look tidy. But it’s small, weak, and inconsistent. If you’re desperate for a paddle, that’s the window. The afternoon holds similar size, 3 ft, but the wind switches to a light cross-on from the NNW, making it a bit bumpier.
Sunday morning the 19th is glassy – wind from the ENE at only 3 mph – but the swell is gone, back down to 1.0 ft. It’s pretty, but you won’t be riding much.
The next little bump comes early on Wednesday the 22nd. We see a bit more size, 4 ft from the NW with a 5-second period, and the combined energy hits 85. The wind is a gentle cross-shore from the NW, so it’s not clean, but it’s the biggest we get in the whole run. It’s still small, short period, and the water is a very unusual 67° – that’s way warmer than normal for this time of year, about 9° above average. That’s a real oddity.
After that, it’s back to almost nothing. There’s a faint sign of life on Saturday the 25th with a weak 2 ft NW swell in the morning, but that’s it. The rest of the run into the end of July and the first day of August is flat, flat, flat. A few glassy mornings for a swim, but not a wave to be had.
If you’re looking for a wave, this isn’t your fortnight. The only time you might get wet is during those small windows on the 18th or 22nd, but don’t expect much. It’s a real desert out there.
Stay patient, lads. It’ll come back.
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.
