The Lowdown
G'day, I'm Rusty. Let's have a look at what's on offer for Rhosneigr over the next 16 days.
Alright, straight up: the outlook for Rhosneigr is a tough one. The water temperature is sitting at 64°, which is a solid 4°F warmer than usual for this time of year – that's a nice surprise. But the surf? It's a long, dry spell. The first real chance of anything rideable won't come until Saturday morning, 29th August. From now until then, it's flat or tiny, with poor conditions.
On Saturday morning, 29th August, we finally see a pulse of 4ft swell from the SSW, with a short period of 7 seconds. The wind is a gentle cross-off from the ENE, so the conditions will be clean. The combined energy is a weak 116, so it's not going to be powerful, but it's surfable. That's the best we've got for a while, but it's really just a small, weak wave.
After that, it's mostly poor again. There's a bigger swell on the way for the first weekend of September. On Saturday morning, 5th September, a 8ft swell from the SW rolls in with a period of 7 seconds. The combined energy jumps to 698 – that's a solid amount of power. But the wind is a light cross-on from the W, which is not ideal, and the conditions are described as marginal. At 8ft, this is only suitable for experienced surfers, and the short period will make it a bit crumbly and messy. It's a standout in size, but not in quality.
Honestly, for the whole 16-day window, it's a pretty lean run. There are no clean, consistent, well-shaped waves on offer. The only real highlight is that Saturday morning, 29th August, dawn session if you're desperate for a paddle. The bigger swell on the 5th is worth a look for the experienced crew, but don't expect perfection.
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.
