Alright, Rusty here again. Let’s call it like it is—this is a grim stretch for Rhosneigr. Over the next 16 days, we’ve got a dead flat start that lasts right through the 17th.
The pattern is ugly. Tiny, gutless surf with cross-onshore winds for days on end. Water temp is running 64°F, which is a solid 4°F warmer than normal for July—you’ll notice that, but it’s the only nice thing in the water. The combined swell energy barely hits double digits most days, reading between 0 and 46 (weak energy). We get some glassy days on the 9th, 13th, and 14th, but with zero swell to work with.
The one real shot comes on the morning of Saturday, 18th July. A SSW swell kicks up to about 6ft with a period of 7 seconds. That’s a short-period windswell, which means the waves will be a bit crumbly, but the combined energy jumps to 324 (moderate wave energy)—a proper spike compared to the dead flat we’ve had. The wind is light offshore from the ENE at just 3 mph, so the surface will be clean. The swell direction is SW, which is the sweet spot for this break. The break is fairly consistent and beginner-friendly at this size, so expect small, rideable waves. Just don’t expect any long lulls.
That afternoon on the 18th, the swell bumps to 7ft, but the wind goes cross from the WNW, so it gets lumpy. The combined energy hits 453 (moderate wave energy), but it’s not as clean. Good only for experts who don’t mind a battle.
After that, it’s back to flat. The 19th onward into early August shows tiny, clean conditions, but next to no rideable swell.
Your play: hold out for the morning of Saturday, 18th July at first light. That’s your window. Before that? Save your energy and check back—these quiet runs don’t usually 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.
