The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Rhosneigr over the next couple of weeks.
I gotta be straight with you from the start – this is a tough one. We're looking at a long, dry spell of just about nothing. The pattern is flat, with mostly poor conditions and onshore or cross-shore winds. You're going to see a lot of "poor surf conditions" in the logs, and I can't sugarcoat it. The first real sign of life is a long way off.
From now until the end of July, it's a write-off. We're talking days of flatness, with tiny dribbles of swell in the 0.3ft to 2ft range, mostly from the west or southwest, but with winds that are either onshore or cross-shore. The water at Rhosneigr is sitting at 63°, which is a touch warmer than normal for this time of year, but you won't be feeling it on a surfboard because there's nothing to ride. The combined wave energy is basically zero (0) for the first few days, and even when we get a little bump, it's weak, like 3 or 27 (moderate energy). It's not worth paddling out for.
The whole first week of August is more of the same. The 1st is flat, the 2nd has a whisper of 0.3ft from the west with a 9-second period, but the wind is on it. The combined energy is just 3 (weak). We're looking at a gap of nearly two weeks with no real surf to speak of.
Now, things start to change a little around the 6th of August. On Thursday the 6th, we finally see a pulse of swell pushing up to 3ft to 3ft from the southwest. The period is short though, only 5-6 seconds, so it's windswell, not groundswell. The combined energy climbs to 41 and then 67 (moderate), so there's a little bit of push. But the wind is a fresh onshore from the southwest at 19 mph, so it's going to be lumpy and messy. The guidance says "poor surf conditions" for a reason. This is the only window with any size, but the quality is just not there for a good paddle session. This setup is more interesting for kite surfing than paddle surfing.
So, let's be honest. There are no standouts here. No sessions to get excited about. The best we can say is that if you're desperate for a splash on the 6th of August, you might find a few small, choppy waves at Rhosneigr, but don't expect any magic. The forecast can change, so keep an eye on it, but for now, this is a blank run.
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.
