The Lowdown
Right then, folks. Rusty here. Let’s be straight with you: the next sixteen days at Rhosneigr are a tough watch. The whole window is a flat spell with barely a ripple to get excited about. We’re looking at a long stretch of poor surf conditions with very little energy on offer, so don't be holding your breath for any hero sessions.
The first proper chance to even think about a paddle comes way down the line, on Saturday the 8th of August. The morning shows a bit of life with a 6ft swell from the west-northwest, and the combined energy of all swells directed here is moderate (178). The wind is offshore from the east-northeast, so the surface should be clean. That’s a decent little window for more experienced surfers, as that 6ft is a bit too big for beginners. The period is short at 6 seconds, so it won’t be packing much punch, but it's the only real chance of a wave in the whole forecast.
Before that, it’s a total blank. From now right through to the morning of the 8th, the swell is tiny, often under 2ft, with persistent onshore or cross-onshore winds making a mess of things. There’s a brief moment of glassy conditions on the 2nd of August, but with zero swell, it’s just a pretty lake. The water temperature is sitting at 63°, which is a touch warmer than normal for this time of year, not that you’ll be in the water enough to appreciate it.
After the 8th, it drops straight back into the doldrums. The 9th offers some clean, offshore winds but the swell is back down to 4ft and dropping, with weak energy (70). The rest of the second week is just more of the same – tiny, short-period slop and poor surf conditions. The 11th of August sees a tiny 2ft swell from the northwest, but the onshore wind will ruin it.
So, what’s the call? The only standout, and it’s a very lonely one, is the morning of Saturday the 8th of August. It’s a long-range call, so don’t bet the farm on it, but if the wind stays clean, Rhosneigr might offer a few fun, punchy waves for the crew who don’t mind a short-period swell. For everyone else, it’s a time to wax the car, not the board.
Rusty.

Information about the Rhosneigr Surf forecast
The above surf forecast table for Rhosneigr provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rhosneigr can be found by selecting the local surf guide option on the grey menu. Our Rhosneigr 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 (Rhosneigr) 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 Rhosneigr 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.
