The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Rhosneigr over the next couple of weeks.
Honestly, it's a pretty grim start. We've got a long stretch of nothing much to get excited about. From the 9th of August right through to the 23rd, the surf is poor to non-existent. Swell heights are tiny, mostly around 0.3ft to 1ft, and the combined wave energy is next to nothing, often in single digits (like 9, 11, 4). There's a bit of a tease on the 18th with a 3ft swell from the SSW, but it's onshore and messy, so it's not worth the paddle out. You're looking at nearly two weeks of flat, windy, or just weak conditions.
The only real glimmer of hope comes right at the end of the forecast period. Keep your eyes on Monday the 24th of August. For the first time in ages, we finally see a bit of life. The swell from the SW picks up to 4ft, and the combined wave energy climbs into the triple digits (116 in the morning, 131 in the afternoon). That's moderate energy, which is a big step up from what we've seen. The wind is forecast to be light offshore from the NE, turning glassy in the afternoon with a slight air. That's a major positive for Rhosneigr, promising clean, lined-up waves.
It won't be huge, but with a 4ft SW groundswell and a 6-7 second period, it'll be a proper wave. The water temperature is sitting at about 63°, which is a touch warmer than normal for this time of year, so a spring suit will be fine. The only downside is that there's only one spot with a recommendation, so if it's working, it might get a little busy. If you've been patient through the drought, this is your window.
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.
