The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

First off, I gotta be straight with you – the charts are looking pretty grim for Rhosneigr. We're staring down a long, dry spell. The first good session isn't even on the radar; we're looking at a solid gap of nothing worthwhile until maybe the very end of the run. The water is sitting at 64°F right now, which feels much warmer than normal for this time of year, but that's about the only nice thing I can say.

We kick off on Wednesday, August 26th, but it's a total non-starter. Tiny, gutless 1ft swell from the SW with a short period, and the energy is barely there (22). The wind is cross-off, so it's clean, but there's simply no wave to ride. This continues day after day. Thursday the 27th is even smaller, with a 0.3ft bump. Friday the 28th through to the end of August sees a bit more size, but the wind turns onshore or cross-onshore, chopping everything up. Even on the 30th, when we finally see a 6ft swell, the wind is a fresh cross-onshore, and the energy climbs to 193, but it's a lumpy, messy mess. The wave comment says it all: poor surf conditions.

Going into September, it's more of the same. Monday the 1st has a 4ft swell, but it's accompanied by a fresh cross-onshore wind, making it choppy and unrideable. September 4th sees the biggest swell of the period at 7ft, with a solid 301 energy, but once again, the wind is a fresh cross-onshore, and the comment is "fresh cross-onshore and lumpy." For a beginner-friendly spot like Rhosneigr, anything over 5ft is already pushing it, and with conditions like that, it's a full-on miss.

The last few days of the forecast, from the 7th, drop back to tiny 0.3ft groundswell with a long 12-second period, but it's clean. The problem is there's no push behind it—energy levels are in the single digits. You'd be floating around on a flat sea.

Honestly, there's not a single standout session in this whole 16-day window. The wind and swell just never line up. The best I can say is that if you're desperate, September 4th has the most size, but it's a messy, lumpy onshore situation that's only really for the hardcore. For everyone else, this is a good time to wax the longboard and wait for a better forecast. It's a tough stretch, but it won't last forever.

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.
