Alright folks, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks at Rhosneigr. I’ll be straight with you – this is a tough run. The pattern is flat, clean, and empty for days on end. We’ve got a massive gap of nothing worthwhile from the start all the way through to the 24th of July. That’s a solid two weeks of no real surf. It’s not unusual for the area when the swell just doesn’t line up, but it’s still a gut punch.
We finally get a whisper of life on the morning of Friday, 24th July. The swell is a tiny 4ft from the WNW with a short period of 5 seconds. The combined energy is weak (77). The wind is light from the north, giving us a clean, cross-offshore look. The water temp is about average for the time of year. This is the only window that even sniffs a rideable wave. It’s small, weak, and the period is so short the waves will be mushy and crumbly. For a beginner, this is about as good as it gets – small, clean, and forgiving. But for anyone looking for a proper wave, it’s nothing to get excited about.
The rest of the 16-day window is a write-off. We’ve got solid offshore winds for days on end, but no swell to push them. Saturday the 12th through Wednesday the 23rd are all clean and flat. It’s a cruel tease – perfect conditions, zero waves. The 22nd kicks up a bit of chop with a cross-shore wind, but it’s still just ankle-snappers.
So, the standout? There’s only one: the morning of the 24th of July. It’s the only time you might get wet. Keep expectations on the floor, but if you’re desperate for a paddle, that’s your window. Forecasts can change, so don’t write the whole thing off just yet.
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.
