The Lowdown
Alright, let’s get into it. Rusty here.
Well, I’ll be honest with you – the next couple of weeks are looking pretty bleak for a proper surf. We’ve got a long stretch of flatness or just tiny, weak waves that aren’t going to get you excited. The good news is the wind is often offshore or clean, but there’s just no swell to work with.
Let’s start with the first few days. From Tuesday the 14th through to the 22nd, we’re looking at a real desert. The swell is barely a ripple, often just 0.3ft or 0.7ft, with periods all over the place but no energy. The combined energy is a measly 10 (10) or less. There’s absolutely nothing to ride. The water at Rhosneigr is a warm 62°, which is 4° above the average for this time of year – that’s notably warmer than usual, but it won’t help the waves.
We do get a tiny bump on the 25th of July, a Saturday, with a 1ft swell from the SW, but it’s still a poor surf situation. The period is a short 5 to 6 seconds, so it’s just windswell junk. The combined energy climbs to 13 (13) – still weak. The wind is cross-off or light, so it’s clean, but the waves are just too small and weak to bother with.
The only slight glimmer in the whole 16-day window comes on Sunday the 26th of July. The swell lifts to 3ft from the SSW, with a period of just 4 seconds. That’s an ultra-short, messy period. The combined energy hits 31 (31) – still weak. But the wind swings from the NW at 12 mph, which is a cross-shore, and it’s noted as having a cross-chop. It’s not good. The setup is a beach break, so this short-period swell is going to be a straight, dumpy mess. Honestly, for a surfer, this is a write-off. If you’ve got a kite, this might be more interesting than a paddle.
The rest of the run into the end of July and early August is more of the same: tiny, onshore-affected windswell with poor conditions. The water is warm, the wind is often clean, but there’s no swell. This is a classic blank run for this area – it’s normal for things to go flat for a while.
So, the short version: No standout days. No waves to speak of. The whole 16-day forecast is a bust for surf. Keep your eyes on the charts, because it tends not to stay this poor for long, but for now, you’re better off doing something else.
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.
