The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks up at Rhosneigr.
First off, I gotta be straight with you. The next 16 days are looking pretty grim for a proper paddle. The surf forecast is a long stretch of tiny, weak waves with poor conditions. Honestly, there’s hardly a single window that’s even worth mentioning for a real surf session. We’ve got a lot of days with no real recommendation, just a blank run of small, messy, or onshore slop.
Looking at the start, from the 6th of August, we’ve got a bit of swell around 4 ft coming from the NW with a short period of just 5 seconds, and a stiff 16 mph cross-shore wind from the WNW. The combined energy is weak at 77, and it’s just a choppy mess. That’s not a surf, that’s a washing machine. The following days are even worse, with swell barely above ankle-snappers and periods all over the place, mostly from the SW or SSW, but with cross-onshore winds from the S or SSW that keep the surface ragged.
There’s a bit of a cleaner moment on the morning of the 10th of August, with a light NNE breeze and a cross-off wind, but the swell is a pathetic 0.3 ft from the SW with a period of 6 seconds. The combined energy is a measly 2. You’d be scratching for a ride. The 11th of August morning has a similar story, with a tiny 0.3 ft south swell and a very light cross-shore wind, but again, no energy to speak of.
The only thing that gets close to being interesting is the morning of the 14th of August, where we see a 3 ft swell from the SSW, but the period is short at 4 seconds and the combined energy is still only 30. The wind is a light cross-shore from the NW, so it’s clean, but the wave quality is poor. It’s a tease.
Later on, the 19th of August morning has a bit more size, with 3 ft from the SW, but a strong 28 mph cross-onshore wind from the SSW blows it out completely. The combined energy is 44, but it’s a messy, blown-out wall of white water. That’s more of a kiteboarding setup than a surfing one.
The 21st of August morning has a similar 3 ft from the WNW with a 16 mph cross-onshore wind from the W. Again, messy and choppy.
So, the honest truth: there’s no standout surf here. No day where the swell, wind, and period line up to give you a clean, ridable wave. If you’re desperate, you might find a tiny, clean ripple on the 10th or 11th, but don’t expect much. The water temperature is unremarkable for this time of year, so no need to worry about a wetsuit change.
Hang in there, folks. It’s a quiet spell, but it won’t 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.
