The Lowdown
G'day, Rusty here. Let's have a look at what's coming up for Rhosneigr.
Honestly, mate, it's a tough stretch. We're looking at a long, flat run to start. The first real sniff of anything rideable doesn't show up until Saturday, 5th of September. Before that, it's a whole lot of nothing—tiny swell, poor conditions, and onshore or cross-onshore wind messing it up. There are a few mornings with offshore wind, like Thursday the 27th and Sunday the 6th, but the swell is so small (0.3ft to 2ft) there's nothing to ride. It's a grim patch until that first week of September is done.
Alright, so the only thing worth talking about is Saturday, 5th of September. The morning is where it's at. We've got a 6ft swell coming from the SW with a period of 7 seconds, so it's a bit short-period, windswell-type energy. The combined energy reading is strong at 674, so there's definitely power in the water. The wind is out of the W at 15 km/h (9 mph), which is a cross-onshore breeze. It's not perfect, but it's light enough that it might clean up a bit. This is a beginner-friendly break, but with the swell over 5ft, it's getting a bit punchy for the absolute newbies. Keep in mind, this spot is fairly consistent, but the quality on the day is only marginal, so it's a gamble. The water temp is around 64°F, which is a touch warmer than usual for this time of year, so you won't need a thick wetsuit.
Beyond that, things go flat again. The afternoon of the 5th drops off to 4ft, and by Sunday the 6th it's back to tiny surf with offshore wind but no size. The rest of the second week looks pretty bleak, with small swell and strong onshore winds dominating. There's a pulse of 5ft on Thursday the 3rd, but it's got strong cross-onshore wind at 25 km/h (16 mph), making it choppy and ugly.
So, bottom line: there's one morning to maybe get wet, but don't expect much. It's a quiet period for Rhosneigr, and you're better off waiting for a proper swell with cleaner wind.
Rusty.

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.

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.
