The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Rhos-On-Sea over the next couple of weeks.
Right off the bat, I gotta be honest with you – this is a tough one. The 16-day window kicks off with a real flat spell. We’re looking at a long stretch of dirt, with no waves worth a paddle from the start all the way through the first week and into the second. You’ll see a few tiny bumps here and there, but the scores are all zero, and the comments are all "poor surf conditions". That’s a solid gap of about two weeks with nothing to recommend.
The first real sign of life won’t show until Monday the 17th of August. That morning, we’ll see a pulse of swell coming in from the northwest, pushing about 8 ft. That’s a solid size – expert territory really, especially with a period of 7 seconds. The combined energy is strong at 704, so there’s plenty of power behind it. The wind is light and cross-shore from the east-southeast, which could keep things relatively clean. It’s a marginal call, and the afternoon drops a bit to 7 ft (466 energy) with a light cross-onshore breeze, so the morning is your best bet if you’re brave and skilled. This is for Rhos-On-Sea, a point break that’s inconsistent, so catching it working is a bit of a gamble.
Tuesday the 18th of August, the swell fades fast. The morning has a tiny 2 ft from the northwest (23 energy) and a light cross-shore, but it’s back to poor conditions. The afternoon is even smaller, 1 ft.
So, the standout here is clear: Monday the 17th of August. That’s the only day with any real size and power. But it’s a big, powerful swell for a spot that doesn’t break often, and the short period (7 seconds) means the waves might be a bit lumpy and less organized. If you’re an experienced local and can read the peak, it could offer a few heavy, high-energy sets. But the rest of the forecast is a barren wasteland.
If you’re a kiter, those windy days in the first week (like Wednesday the 5th with 25 mph cross-offshore) might look more interesting than anything a surfer would chase.
Stay patient, and keep an eye on the charts – it tends not to stay this quiet forever.
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.
