The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks for our local stretch of coast.
Right, let's be straight with you. The Rhos-On-Sea (point) is not looking great for a long while. We have a massive stretch of flat, poor, or rubbish conditions stretching from now right through until the end of the first week of September. There’s hardly anything on offer. A few little dribbles of windswell here and there, but with onshore breezes and no power behind them, they aren't worth paddling out for. The water is 66° – that’s a massive 6° warmer than average for this time of year, proper bathwater.
You’ll be waiting until Thursday the 3rd of September for the first real chance. That morning we get a pulse of groundswell from the WNW pushing 7ft. Combined energy is moderate at 293. Period is short though, only 6 seconds, so it’ll be a bit walled-up and fat, better for the bigger boards. The wind is dead glassy though, so if you pick your moment it will be clean. That 7ft is borderline big for beginners, though. The direction is WNW which is a solid match for this point's optimum NW. It won't be epic, but it is the first window of something rideable.
After that, it goes a bit messy again, but hold onto your hats. If you can wait all the way to Tuesday the 8th of September, things get interesting. The morning shows a proper pulse of swell from the WNW pushing 8ft with a combined energy reading of 639 – strong stuff. Period is still a short 7 seconds, so it’s powerful but a bit dumpy. That size is strictly for experienced surfers only; the white water will be heavy. Wind is clean offshore from the West, setting the waves up nicely. This is the standout of the whole period. It’s a long way out, so the forecast could shift, but it’s the one to keep an eye on.
The rest of that week is just small stuff and cross-shore winds. A long, lean spell, but that early September window might just save it.
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.
