The Lowdown

Alright folks, Rusty here. Gotta be honest, the next couple weeks at Rhos-On-Sea are a write-off. We're looking at a long stretch of flatness, so don't rush to grab your board. There's a big gap with absolutely nothing at the start, and it doesn't really improve from there.

The first bit of anything shows up on Wednesday the 16th, but it's a letdown. A weak 6ft windswell from the NW, with a short period of 6 seconds. The combined energy is moderate at 212, but it's not lined up right for the break. The wind is cross-offshore, so it'll be clean, but this weak, short-period stuff won't give you anything worth paddling for.

That pulse dies down fast, and it's flat all over again. The following Tuesday, the 22nd, we see a slightly smaller 5ft from the NW, still with that short 6-second period. The energy is even weaker at 127. After that, it's all over. From the 23rd onwards, it's just tiny, dribbly leftovers – 2ft with 4-second periods. That’s not surf, that's just bumps on the water.

We get some glassy mornings on the 24th and 25th, but with no swell, it's a lake. The 26th throws up a weak 4ft from the NNW, but the period is only 5 seconds and the energy is a paltry 69. It won't break properly at this spot.

So, for the whole 16 days, there isn't one decent session. The best is that first Wednesday, and even that is marginal. The wind is often offshore and clean, but that doesn't matter when there are no waves. The water is much warmer than usual for this time of year, so a dip is fine, but a surf? Forget it.

Beginners shouldn't even think about it. The few moments with any height are still under 5ft, but the quality is so poor it's not worth the effort. This is a good time to clean your wetsuit and wait for a proper groundswell. A blank run like this happens here sometimes, so don't get too down about it.

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.

Rhos-On-Sea is 2 km (1 miles) from Colwyn Bay. If you plan a holiday in North Wales, look for hotels and other accommodation in Colwyn Bay. Colwyn Bay has rooms for a wide range of budgets as well as car hire and transport links.
