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 gotta be honest with you – this is a tough one. The forecast is lookin' pretty barren. There’s a big gap of flat, poor surf conditions from now, all the way through the end of July and into the first days of August. You’re lookin' at a solid week or more with no real swell to speak of, just a whole lot of wind and not much else. It’s a bit of a bummer.
We finally see a little pulse of energy on Sunday, the 2nd of August. The morning brings a glassy, clean surface with a tiny 2 ft swell from the NW, but it’s a short period of 4 seconds, so it’s gonna be weak and mushy. The combined swell energy is a measly (8), so don’t expect much. The water temp is about average for the time of year, nothing weird goin' on there.
The rest of that first week of August stays pretty grim. More tiny, weak swell lines with periods barely over 4 seconds, and the wind is all over the place – cross-on, onshore, the works. The combined energy barely gets above (23) on the 6th, and even when it’s glassy on the 7th with a little 3 ft bump, the period is still a pitiful 4-5 seconds. It’s just not got any grunt.
The second week of August looks a bit more promising on the surface, but still nothing to write home about. We start seeing small swell again from the 10th, with a bit more size – up to 3 ft from the SE on the Monday morning. The wind is light and cross-off, keepin' it clean. Still, these are short-period wind swells, period only 4 seconds, so it’s gonna be fat and slow. The combined energy stays in the low teens (17, 13, 15), so it’s just weak.
The standout here, if you can call it that, is the morning of Thursday, 7th August. It’s dead flat calm, glassy as a mirror, with a 3 ft lump from the NNW. The combined energy hits (28) – the highest in the whole run. But, and this is a big but, it’s an inconsistent point break, so you might score a few fun little waves if you’re patient, but it’s not gonna be pumping. The period is still only 5 seconds, so it’s a very local, crumbly wave.
Overall, for the next 16 days, Rhos-On-Sea is a tough call. The early part is a total write-off. The back half offers a few small, clean windows but the swell is weak and short-period. The best look is that glassy Thursday morning on the 7th, but don’t go expecting any barrels. For a beginner, the very small size (2 ft – 3 ft) is fine, but the lack of power and consistency makes it a bit of a mission. This is just one of those flat spells the area can get.
Rusty out.

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.
