The Lowdown
Alright, let’s be real. Looking at Rhosneigr, it’s a grim start. For the first week and a half, it’s flat or it’s junk. There are big gaps of days where there’s nothing worth paddling out for.
The only thing that shows any life is way out there. On Friday, the 7th of August, we get a late spike. The afternoon brings a 7ft swell from the SSW, with a short 7-second period. It’s got a combined energy of 394, which is strong, but it’s coming with a 15 km/h onshore wind from the SW. That’s a big, lumpy, close-out mess. It’s a powerful wave, but it’s not clean. This is for the experienced crew only.
Saturday, the 8th of August, the swell drops to 6ft out of the SW, still with that short 7-second period. The afternoon sees it drop to 6ft, and the wind is a light onshore from the SW. The water temp is about 62°, which is a touch warmer than normal for the time of year. It’s a novelty, but it won’t clean up the chop.
If you’re really jonesing, the 1st of August has a clean 2ft, and the 2nd of August has a clean 3ft, both with offshore winds, but the energy is tiny. You’d be on a longboard, scratching for nothing.
The bottom line: the first 13 days are a total loss. Friday the 7th is the only day with any real punch, but it’s a brute. That Saturday afternoon sets up with a cross-onshore wind, so it might be more interesting for the kite surfers than the paddlers. For the rest of us, it’s a waiting game.

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.
