The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a rough one. We’re looking at a real dry spell. There’s basically nothing on the cards for the first week and a half. From now all the way through to the 25th of July, the surf is either flat or just tiny, weak, and messy. You’ll see a few odd pulses of long-period swell, but they’re barely registering any energy (single digits in the combined energy), and the wave heights are laughable – 0.3 ft to 0.7 ft. It’s not worth paddling out for. The wind is mostly offshore or cross-offshore, which is nice for the soul, but without any swell, it’s just a pretty lake.
The only real glimmer of hope comes right at the very end of the outlook. On Sunday the 26th of July, we finally see a bit of a pulse. The afternoon shows a 4 ft swell from the SSW, with a period of 5 seconds. That’s a short, weak windswell, and the combined energy is only 77 – weak. The wind is onshore, so it’s gonna be a bit messy. Still, it’s the best we’ve seen in days.
Then Monday the 27th and Tuesday the 28th of July bring a bit more size, but the quality is still poor. Monday morning hits 5 ft from the WSW, but it’s onshore with a fresh 19 mph wind, and the period is a short 5 seconds. The energy climbs to 98 (still moderate at best). Tuesday the 28th is a write-off – strong onshore winds up to 25 mph, and the swell is dropping back to 2 ft. It’s a lumpy, messy mess.
The bottom line: There’s no standout session here. This is a two-week period where the sea just couldn’t be bothered. There’s a gap of nearly 12 days with no real surf. The only thing worth mentioning is that run from the 26th to the 29th, but it’s strictly for the die-hards or those who just want to get wet. The water temperature is about average for the time of year, so no surprises there.
For a beginner, even the 4 ft-5 ft stuff is manageable, but the onshore wind will chop it up. Not a classic.
Rusty, signing off.

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.
