The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for Rhos-On-Sea over the next couple of weeks.

Straight up, I’ll be honest with you – this is a grim stretch for surf. We’re looking at a long, barren run. From now until the morning of September 9th, there’s barely a ripple worth paddling for. Days and days of flat, poor conditions with only tiny, short-period dribble showing up on the 5th – that’s 2ft from the NNW with a period of just 5 seconds, and wave energy at a pathetic 17 – just not worth getting wet for. You’ll be waiting over a week for anything with a pulse.

The only real window of interest appears on Wednesday the 9th. The morning brings a solid 8ft swell from the WNW with a period of 7 seconds and strong, moderate wave energy registered at 728. That’s a fair bit of water, too big for beginners, and it’s coming in with moderate cross-offshore breezes. It’s a marginal call with questionable tide conditions though. The afternoon shapes up a bit better for the paddle crew – the swell drops to 6ft from the NW, still with a 7-second period, but the wind goes gentle offshore from the SSW. That tidies things up nicely, giving us "expect good surf conditions" and still decent energy at 315.

For a spot like Rhos-On-Sea, a point break that’s inconsistent and rarely works, this is about as good as it gets in this outlook. The optimum swell direction is NW, and that’s exactly what we’ve got on the 9th. If you’re an intermediate looking for a session, bank on the afternoon of the 9th. It’s the standout by a long shot.

After that, we’re back to the doldrums. Tiny, weak slop from the 10th onwards – 1ft here, 2ft there – with periods barely cracking 3 or 4 seconds and energy in the single digits. Some glassy mornings on the 11th and 13th might look pretty, but there’s nothing underneath them. It’s a proper blank spell for the second week.

Stay patient. When the swell does show, it’s worth a look.

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.
