The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this is a tough one. We’re looking at a solid 16-day window for Rhosneigr, and honestly, it’s about as flat as a millpond for most of it. The forecast is a long, quiet stretch with very little to get excited about.
Right from the start, we’ve got a few tiny pulses of swell, but nothing that’s going to get you out of bed. On Wednesday the 15th, we’re looking at a 0.3ft swell from the SW with a very long period of 16 seconds, but the combined wave energy is a measly 14, so it’s barely a ripple. The wind is offshore and clean, but the swell just isn't there. It’s a similar story through the rest of the week and into the next. The breaks are mostly exposed to the SW, which is the right direction, but the energy is just not delivering.
There’s a real gap here. From the 15th of July right through to the 23rd of July, there’s just nothing doing. The combined energy figures are mostly in the single digits or zero. It’s frustrating, but these blank runs happen. The water temperature is about average for the time of year, so at least a paddle won’t be a shock.
We finally get a little flicker of life on the 23rd of July, Thursday morning. A 0.3ft SW swell shows up, with a period of 14 seconds, and the wind is glassy. That’s a beautiful thing to see, but the wave energy is still only 12. It’s a tease. A near-flat, glassy morning is lovely for a swim, but not for a surf.
The only other time we see a bit of push is on the 24th of July, Friday afternoon, when a 1ft swell from the WNW appears, but it has a period of just 4 seconds – that’s pure wind chop and it’s coming in with an onshore wind. The rest of the forecast is a mix of onshore and cross-onshore winds and tiny, short-period slop. For the final week, it’s consistently poor, with some rain showers and fresh breezes making it look even less appealing.
The setup here is more interesting for kite surfing than paddle surfing for most of the period. There are no standout days, no hidden gems. The best you can hope for is a glassy, flat paddle on the 23rd. For surfing, this one’s a write-off. Forecasts change, but right now, I’d be finding something else to do.
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.
