The Lowdown
Alright folks, Rusty here. Let's be straight with you. We're looking at a pretty grim stretch for Rhosneigr. The next 16 days are a real write-off for any kind of decent surf, so don't get your hopes up.
The wind is just a mess for most of the coming days, and the swell is barely registering. From now through the first week of August, it's a constant battle of cross-onshore winds and tiny, weak waves. The water is sitting at about 62°, which is a touch warmer than normal for this time of year, but that's the only bright spot. You're looking at swell heights of 0.3ft to 2ft, with periods so short they're just wind slop. The combined energy is laughable, staying in the single digits (10) and low teens (16) – there's just no power behind it.
We get a glimmer of something on the 2nd of August with a glassy morning, but the swell is a pathetic 0.7ft – it's a total flat spell. The 8th of August morning offers a clean, cross-off wind, but again, the swell is only 1.3ft with a 7-second period. It's barely a ripple. The only real "energy" we see is on the 14th and 15th of August, with the combined energy finally hitting 22 and 35, but the swell is still only 2ft to 3ft with a short period. On the 14th, the wind is a fresh 19 mph cross-onshore, so it'll be lumpy and horrible. The 15th afternoon has a slightly better NW 3ft swell, but it's still cross-shore and messy.
There is no standout. There is nothing to get excited about. For a beginner-friendly spot like Rhosneigr, this is a very long, blank run. It's a tough stretch for the area, but that's how it goes sometimes. The forecasts can always change, but right now, don't bother paddling out.

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.
