The Lowdown
Right then folks, Rusty here. Let’s have a look at what’s cookin’ for Rhosneigr over the next couple of weeks.
Honestly, I gotta be straight with you – this is a grim run. We’re looking at a solid 16-day window with absolutely no surf worth paddling out for. The whole forecast is just a write-off of poor surf conditions. There’s a massive gap right from the start, with nothing on offer through the end of July and well into August.
The water’s sitting at 62° and feels a touch warmer than normal for this time of year, which is about the only good thing going on, but it won’t help you catch a wave.
A little bump of energy pops up on the 4th of August, with a combined energy of 162 (moderate) and a 4ft swell from the SW, but it’s a short-period, wind-battered mess. The wind is howling cross-onshore, making it lumpy and hopeless. Anything else that shows up is tiny, weak, and chopped up. The energy readings are pathetic, mostly in the single digits or low double digits – weak doesn’t even cover it.
Even the days with glassy or clean conditions, like the 2nd of August, have zero swell. You could water-ski, but you won’t be surfing. There’s a long stretch of nothing, and then by the second week, it’s just a dribble of tiny, short-period slop that never gets its act together.
To be fair, this area can have these blank runs, and it’s just one of those times. The conditions are so poor that even the 4ft days are completely ruined by the wind. Don’t bother. Wait for the next chart.
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.
