The Lowdown

Right then, let’s have a look at what’s on offer for Rhosneigr. To be honest, mate, it’s a bit of a slow burner. The water’s sitting at 65°F which is much warmer than normal for the time of year, so that’s a nice surprise if you’re getting in.

For the first week, it’s pretty grim. Saturday the 22nd, Sunday the 23rd, and Monday the 24th are all a flat, wobbly mess with tiny 0.3ft swell. There’s a bit of glass on Monday morning, but with nothing to ride, it’s a day for a paddle at best. Tuesday and Wednesday the 25th and 26th aren’t much better, with weak, short-period stuff. Thursday the 27th afternoon sees a spike in energy – a 7ft swell from the SSW with a short period of 7 seconds – but it’s coming straight onshore with a risk of thunderstorms, and the combined energy is a meaty 455 (moderate wave energy). That’s a messy, lumpy mess for experts only, and honestly, looks more like a kite session than a surf.

Friday the 28th keeps the onshore wind, with a 6ft SSW swell (523 combined energy) in the morning, but it’s still a bit of a choppy thing. The weekend of the 29th and 30th is cross-onshore and lumpy, with dropping swell. Then we hit a proper gap of no real surf from the 31st right through to the 1st of September.

Now, the real standout – and it’s a long-range promise, so keep your fingers crossed – comes on Wednesday the 2nd and Thursday the 3rd of September. Wednesday morning serves up a clean 4ft SW swell with a gentle offshore breeze from the ENE. That’s surfable, but the afternoon is where it gets interesting: 5ft SW swell, period 6 seconds, with a clean offshore wind from the NE. The combined energy jumps to 182 (moderate wave energy). It’s not huge, but it’s clean and rideable. Thursday morning holds onto that 5ft SW swell with light offshore winds, so a good window for a cruisey session. The short period means it’ll be a bit fat and won’t have much punch, but it beats the flat spell we’ve had. After that, it fades back to nothing.

So, the best bet is the Wednesday the 2nd and Thursday the 3rd of September. The rest of the window is a write-off.

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.
