The Lowdown
Alright, Rusty here. Let's have a look at what's on offer for the next couple of weeks.
Right off the bat, I gotta be honest with you – this stretch is looking pretty bleak. The first real surf we see is small and weak, and it doesn't get much better. For a point break that's inconsistent, it's a frustrating run. The water's sitting at 65°F which is much warmer than usual for this time of year, a real anomaly.
We start off on Sunday the 2nd with nothing. Monday the 3rd is the same story – tiny, weak waves. By Tuesday morning the 4th, we get a tiny 0.7ft swell from the ESE, but with a combined energy of just 1 (weak), it's barely a ripple. The wind is light cross-off though, so it's clean, but there's just nothing to ride.
The first hint of something bigger comes on Thursday morning the 6th. We see a 6ft swell from the WNW, with a period of 6 seconds and a combined energy of 254 (moderate). That's a bit of size, but the period is short, so it'll be a bit of a mess. Still, the wind is cross-off and clean. It might be worth a look for the more experienced among you, but with the inconsistency of this spot, don't expect magic.
The rest of the first week and into the second is a whole lot of nothing. There are occasional pulses of 2ft to 3ft from the NW, like on Sunday the 9th and Monday the 10th, with combined energy in the teens to low twenties. The wind stays clean, but the swell is tiny and weak. You'll be scratching for anything.
Thursday the 13th, Friday the 14th, and Saturday the 15th are completely flat – glassy and calm, but no surf. It's a proper blank run.
Finally, on Sunday the 16th, we get a little bump. A 4ft swell from the NW with a 5-second period, and a combined energy of 60 (weak). The wind is light and cross-shore in the morning, but it turns onshore in the afternoon. It's not great, but it's the best we've seen in a while.
Honestly, there's no standout session here. The conditions are often clean, but the swell just isn't cooperating. If you're desperate, Thursday the 6th has the most size, but it's short-period and a bit messy. Otherwise, it's a waiting game. Forecasts can change, but for now, the boards are staying in the van.
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.
