The Lowdown
Alright, Rusty here again, with the same news but in feet and Fahrenheit for you.
Rhosneigr is looking at a long, flat spell. There’s no good surf on the cards for the full 16 days – every single time slot is rated as poor surf conditions. So don’t get your hopes up.
The first hint of anything is around Friday 24 July, but it’s tiny – a 0.3ft south swell with a 13-second period. Energy is barely there, just 3. Light cross-shore wind in the morning, then onshore. Not worth looking at.
Saturday 25 July shows 3ft from the WSW, but with a period of only 4 seconds – that’s short-period junk. Wind is onshore. Sunday 26 July is even smaller at 1ft. All of it is poor.
The biggest push comes on Tuesday 28 July afternoon, with 4ft from the SSW, period 5 seconds, and combined energy of 54. But it’s cross-onshore and choppy. Still poor.
On Friday 31 July, the afternoon bumps up to 5ft from the SSW, period 6 seconds, and energy hits 160 (moderate). But the forecast says poor – cross-onshore wind and choppy.
Then on Sunday 2 August, the afternoon shows 6ft from the SSW, period 6 seconds, combined energy 209 (moderate). Again, onshore wind and poor conditions. That’s as big as it gets, but it’s not clean.
Water temp is 63°, which is about 3° warmer than usual for this time of year. Not that it makes any difference with no waves.
So, no standout days. Nothing to recommend. For Rhosneigr, a run like this happens sometimes. Kite surfers might get something out of those onshore, 5ft afternoons, but for paddle surfing, it’s a washout.
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.
