The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for Rhosneigr over the next couple of weeks.
Honestly, mate, I’ve got to be straight with you – this is a tough run. The whole 16-day window is a pretty flat and messy affair. There are no real standout days, and the surf is small and mostly blown out. We’ve got a long stretch of poor conditions, with only a few moments where it might be worth a paddle, but even then, it’s nothing to write home about.
The first real chance of anything rideable comes on Tuesday morning, 4th August. The swell is tiny at 1ft from the SW, but the wind is glassy – dead calm. That’s a big positive for clean conditions, but with such little energy (combined swell energy only 10), it’s really only for the beginner crew or someone with a longboard looking for a gentle glide. The water temp is about average for the time of year, so no surprises there.
Wednesday the 5th sees a slight bump in swell, up to 3ft from the SSW, but it’s a short-period windswell (6 seconds) and the wind is onshore in the morning, making it choppy. The combined energy hits 51, which is still weak. Not great.
Thursday the 6th is more of the same – small, short-period swell and cross-shore winds. The afternoon clears up but the waves are still poor.
The best looking conditions in the whole run are actually on the morning of Monday the 10th of August. We’ve got glassy conditions again, with a 2ft SSW swell. The combined energy is only 8, so it’s tiny, but it will be clean. That’s about as good as it gets, and it’s still not great.
Things pick up a bit on Tuesday the 11th of August, with the swell jumping to 4ft from the SSW by the morning, and 5ft in the afternoon. The combined energy hits 156 in the afternoon – moderate energy. But the wind is cross-onshore to onshore, so it’s going to be choppy and messy. For a beach break like Rhosneigr, that’s not going to be pretty. At 5ft, it’s still okay for intermediates, but the wind will ruin it.
After that, it’s a slow decline into even smaller, wind-affected waves. The 15th of August brings a 4ft NW swell but with a fresh cross-onshore wind at 18 mph, making it lumpy and poor.
So, here’s the honest truth: there are no standouts. The best surfs are the glassy, tiny mornings – Tuesday 4th and Monday 10th – but you’ll be on a foamie or a log. If you’re an expert looking for a proper wave, this forecast is a dud. The water is about average for the time of year, which is neither here nor there.
Keep an eye on it, but don’t hold your breath. It tends not to stay this poor for long, and forecasts can change. But for now, it’s a flat spell.
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.
