The Lowdown
Alright my friends, Rusty here, and I’m going to call it like I see it. We’ve got a long, flat stretch ahead at Rhosneigr – the finder is showing all zeros for the next 16 days. There’s no surf worth paddling out for.
The first record is Wednesday 29th July, and it’s a dud: a weak 3ft swell from the SSW with a short 4 second period, combined energy of just 22 (very weak). With a cross-on 16 mph wind, it’s choppy and ugly. No thanks.
Thursday 30th and Friday 31st July are even smaller – 1ft to 0.7ft. The wind is light cross-on, but the energy is gone. Tidal ripples.
The weekend of August 1st and 2nd sees a little cleaner wind, especially Sunday morning with a light offshore from the NE, but the swell is barely a bump – 0.7ft at best. The combined energy is 3. It’s clean, but there’s nothing to ride.
From Monday 3rd August right through to Thursday 13th August, we get a long run of offshore or cross-offshore winds, mostly from the NE and N. The water will be clean, but the swell heights are stuck at 0.3ft. Periods do get longer (up to 13 seconds on the 5th and 6th of August), which would normally be a sign of a proper groundswell, but with no height, it’s just a flat ocean with a pulse. Combined energy never gets above 7.
Water temp is about normal for this time of year, nothing unusual.
When the finder throws up 16 days of zeros, it’s a tough pill to swallow. A blank run like this is more normal for the area, but it won’t stay flat forever. Forecasts can change, so keep watching. For now, the setup looks more interesting for kite surfing than paddle surfing. Hang loose.
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.
