Alright folks, Rusty here. Let's get straight into it for our local stretch.
Honestly, looking at the next sixteen days, it’s a real tough one. For the vast majority of the period, it’s looking pretty flat or just too weak and messy to bother paddling out. We’re looking at a long dry spell from the start all the way into the second week.
The first real sign of any pulse, and I mean just a whisper, shows up on Tuesday, the 14th of July. We’ve got a tiny 0.3ft swell sneaking in from the SW, but with a surprisingly long 18-second period. This is a long-period groundswell, so while it’ll have some energy for its size (combined energy of all swells directed here is only 14), it's going to be super inconsistent and mostly better suited for a reef or point. At Rhosneigr (Wales) here, it’s exposed and a beach setup, so that long period might make it break too straight. Winds are clean, coming from the NNW at 9 mph as a cross-offshore, which is about the only positive. This is not a standout; it’s just the only thing on the table.
The following days stay frustratingly small. We see another 0.3ft blip on Thursday afternoon the 16th of July, with a 14-second period swell from the SW, and the wind goes totally glassy. The conditions will be perfect, but with the combined energy (9) being so weak, you’ll be waiting an age between knee-high dribblers. It’s not really surfable.
If you’re a beginner, don't even think about it – nothing gets over 5ft, so there’s no danger from size, but there’s also nothing to catch. For the more experienced, it’s a waiting game. This kind of blank run can happen here, though it’s a bummer. The forecasts can change, so keep an eye out, but for now, sharpen your wax comb and work on the ding repairs. No standout windows at all.
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.
