Hey folks, Rusty here. Let's have a look at what we've got coming up at Rhosneigr over the next couple of weeks. I gotta be straight with you – it's looking like a proper quiet spell for the waves. The whole period is a bit of a write-off for any decent surf, so don't be rushing to grab your board just yet.
The water's sitting at 61°, which is a touch warmer than normal for this time of year. That's about the only thing that's slightly out of the ordinary.
We kick off on Saturday, July 4th with a wobbly 3ft swell from the SW, but it's a short-period windswell and the wind is howling onshore at 16 mph. That's making a mess of things, with combined swell energy only sitting at a weak 41. It's all poor surf conditions from the get-go.
Sunday the 5th is more of the same, with the swell dropping to a tiny 2ft and the wind still onshore. Monday the 6th sees the swell fade further to 1ft, with a pathetic combined energy of just 9, and it's cross-onshore by the afternoon. The poor run continues right through the first week. We get a glassy morning on Wednesday the 8th, but there's absolutely no swell at all. The best we see is a clean, glassy morning on Friday the 10th with a 0.3ft swell from the south – barely a ripple.
Heading into the second week, it doesn't get any better. There are days with no swell at all, and when there is a tiny bit of energy, it's in the form of long-period groundswell (11 to 18 seconds), but it's only 0.3ft. Saturday the 11th offers clean cross-offshore winds, but still no height. Tuesday the 14th and Wednesday the 15th have some cleaner windows and a 0.3ft groundswell, but you'd be lucky to find a wave you can even stand up on. It's pretty much a blank run for the whole sixteen days.
Rhosneigr is a beginner-friendly spot that can be fairly consistent when the swells are running, but right now, there's just nothing doing. Forecasts can change, but as it stands, you're better off leaving the board in the shed.
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.
