Alright, I’m lookin’ at this one, and honestly, it’s a tough stretch for Rhosneigr. The whole 16-day window is pretty flat, with barely a ripple worth paddling for. There just isn't any real surf energy coming in, so don't expect to get your feet wet with anything decent anytime soon.
We start off the first week with tiny, weak swells. On Sunday the 5th of July, you’re lookin’ at a meagre 2 ft from the SW with a short period of 6 seconds, but it’s onshore wind and just messy. The combined energy is only a weak 27. Water temp’s sittin’ around 61°, which is a touch warmer than normal for this time of year – that anomaly of 3° is notable, but it won't make the waves any better. It's really just poor surf conditions, mate. That continues through Monday, Tuesday, and Wednesday – we’re talkin’ about ankle-high slop at best, if that, with most days showing zero swell.
Then there’s a long dry spell. From Wednesday the 8th of July right through to Saturday the 19th of July, there’s hardly any swell registered – most entries show no height at all. The few tiny pulses on the 14th and 15th are just 0.3 ft from the SW, with periods over 14 seconds, but the combined energy is laughable – well under 15. Even with clean offshore winds on some of those days, there simply isn't enough water moving to break. It’s a total blank run.
If you’re after a silver lining, the Thursday the 16th of July morning has a tiny 0.3 ft SW groundswell with a 14-second period and clean NE offshore winds at 9 mph. But mate, that’s a wave for a toy boat, not a surfboard. The whole setup is so weak – combined energy of just 7 – it’s more a glass-off for a swim than a surf.
Bottom line: there’s nothing here to get excited about. For a spot that is fairly consistent, this is an unusual dead period. Keep an eye on the charts – it tends not to stay this poor for long.

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.
