The Lowdown
Alright, I’ll be honest with you – this stretch for Rhosneigr is pretty grim. Over the next 16 days, there’s hardly any surf to speak of. The whole forecast is filled with "poor surf conditions" and tiny swell. It’s a long, flat spell with nothing worth paddling out for.
From Tuesday 14th July through Sunday 20th, the swell is just 0.3ft to 0.7ft – that’s ankle-biters. The combined energy is weak, mostly single-digit numbers (10 or less). Even with clean offshore winds, there’s no wave. The water temp is 62°, which is about 4° warmer than usual for this time of year – that’s a pleasant surprise for a dip, but it won’t help the surf.
Around Wednesday 22nd July, there’s a tiny bump: 1.0ft in the morning with a period of just 4 seconds, and energy of 2. That’s a total dud. The wind is light and offshore, but you’d be floating on flat water.
By Saturday 25th July, we see a slight increase to 1ft with a period of 7 seconds and energy of 16 in the morning. Still not enough to ride. Winds are clean and cross-offshore, but the swell is just too small.
Then on Sunday 26th July, there’s a cruel tease: the morning shows 2ft from the WNW with a period of 4 seconds and energy of 14, and the wind is glassy – dead calm. That’s the best-looking conditions in the whole 16 days, but the swell is still tiny and short-period. For a beginner spot like Rhosneigr, even 2ft can be rideable if it’s clean, but with such a short period and weak energy, it’s going to be gutless and inconsistent.
The last few days, 27th to 29th July, keep the same pattern: 0.7ft to 1ft, poor surf, and weak energy. The glassy moments on the 28th and 29th morning are nice, but again, there’s just no power behind it.
So, bottom line: there’s no standout session here. The whole 16-day window is a washout for surfing. The area is known for being fickle, and this is one of those blank runs. Forecasts can change, but right now, I’d leave the board at home and just enjoy the warm water. The waves are taking a long nap.

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.
