The Lowdown
Right, Rusty here. No two ways about it – the 16-day run for Rhosneigr is a total washout. There’s zero surf worth paddling for from Thursday the 23rd of July all the way through to Friday the 7th of August. Every single session in the forecast is marked as poor. The biggest combined wave energy you get is a weak 67 on the afternoon of the 1st of August, but that's with a 4ft swell from the SSW and a piddly 5-second period – that’s just windswell slop.
The water temp is about 63°F, which feels a touch warmer than normal for this time of year (about 3°F warmer than average). Not that you’ll be out there to feel it.
Winds are onshore or cross-onshore pretty much the whole time, often blowing 12 to 18 mph, sometimes stronger. The swell direction never matches what Rhosneigr needs, and the periods are almost always under 10 seconds. It’s flat, choppy, or both.
There is nothing to get excited about. When the swell is this weak and the wind is this messy, the whole setup looks better for kite surfing than paddle surfing. It’s a dead period, but these stretches don’t usually last forever. Forecasts can turn. For now, leave the board in the car.
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.
