The Lowdown
Alright, let’s get down to it. The next couple of weeks are looking pretty flat around here, honestly. For a stretch, there’s just nothing doing. The first real sniff of surfable waves won’t show up until well down the line, and even then it’s going to be a struggle to find much to get excited about.
We’re looking at a long gap here, with no decent surf on the cards at all for the first several days. Everything from now through to around the 24th of July is basically a write-off. There’s just no swell reaching us, and the wind isn’t doing us any favours either.
Finally, on Friday the 24th of July, we see a tiny pulse of swell arrive at Rhosneigr. It’s a bit of a tease, to be honest. We’re talking about a 0.3 ft swell coming from the south with a wind that’s mostly cross-on, so it’s not going to be pretty. The water temp is sitting at 63° which is a touch warmer than normal for this time of year, but that’s about the only positive.
The rest of the period just doesn’t deliver. There are a few days where the swell bumps up a little, like on Saturday the 25th with some 3 ft, short-period stuff, but it’s coming with onshore wind and it’s going to be choppy. None of it ever breaks the threshold for being worth a paddle.
By the time we get into the first week of August, conditions are still poor. The swell is tiny, the wind is messy, and it’s just not going to happen. Even with a glassy morning on the 29th of July, the swell is barely a ripple at 0.7 ft.
So, what’s the best on offer? Honestly, there isn’t a standout. The whole 16 days is a flat spell. For surf, it’s a bust. The combined energy numbers are all in the dregs, almost always below 100 (often just 1, 3, 9, 64 on the 2nd of August). That tells you everything. The setup looks far more interesting for a kite surfer than anyone with a paddle, but that’s about it.
Keep an eye on the forecasts. It tends not to stay this poor forever.

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.
