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, it's a tough stretch. We're looking at a real dry spell with barely a ripple for days on end. The water is sittin' at a balmy 66°, which is much warmer than normal for this time of year, so at least it'll be pleasant just to float about if that's your thing.
The forecast is almost all zeros – poor surf conditions, tiny or no swell, and not much to get excited about. We’ve got a long gap with no real recommendations. It’s not until Monday the 10th of August that we even see a pulse, and even then it’s a sad little 1ft from the NNW with a pathetic 3-second period. The combined swell energy is a measly (2), so barely any power behind it.
Tuesday the 11th is more of the same, just weak and small. There’s a slight uptick on Wednesday the 12th, with a 2ft swell from the SE and the energy creeping up to (6), but it's still messy with moderate cross-shore winds. It's just not worth paddling out for.
The pattern just keeps going – tiny, weak, and mostly cross or onshore winds. We get another little spike on the 21st of August with a glassy 0.7ft from the NNW, period a bit better at 4 seconds, but energy is still only (1). The next day has a similar 1ft from the NW with energy at (3), but it’s cross-onshore. Honestly, nothing here is a standout. For a spot that’s already inconsistent, this is a proper flat spell.
If you absolutely have to get wet, keep an eye on the 12th of August, but even then, don’t expect much. It’s a point break that’s fairly exposed to the NW, but the swell just isn’t there. Right now, the setup looks more interesting for a bit of a paddleboard cruise than any proper surfing.
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.
