The Lowdown
Alright, you know what, I've been staring at the charts for Rhosneigr and, well, it’s a bit of a tough pill to swallow. The next sixteen days are looking pretty bleak, to be honest. We have a long stretch of poor surf conditions, and for the majority of this period, you'd be better off leaving the board in the shed.
The problem is the wind. For days on end, it's coming from the west and southwest, blowing straight onshore or cross-onshore at a good clip. That’s just going to chop everything to pieces. There's a bit of swell around, but it's not doing us any favours with that wind.
Let’s look at a few examples. On Friday the 29th of August, we have a bit of hope with a clean, light cross-offshore breeze in the afternoon, but the swell is tiny, only 2ft from the SSW with a miserable 6-second period. The energy is weak (25). It’s barely surfable.
Then we get a pulse of more size on the morning of Monday, the 1st of September. Swell hits 5ft from the WNW with moderate energy (220), but it's accompanied by a fresh cross-shore wind (19 mph) that will make it lumpy and hard to manage. And again on Wednesday the 3rd, we see 8ft from the SW with strong energy (525), but that fresh cross-onshore wind (19 mph) will have it blown out and messy. That’s possibly one for kite surfers, not for paddle surfing.
There’s a small window on the morning of Saturday the 6th of September where it goes clear with a light cross-shore breeze, but the swell is a pathetic 3ft from the WNW with a short 4-second period (45). You’ll be bobbing around more than surfing.
We then hit a dead zone from the 7th of September onwards, with next to no swell and then flat days leading into the second week. There’s a little bump of size on the 12th of September, with a 8ft SSW swell showing strong energy (527), but it’s met with another strong cross-onshore wind. Just when you think it might get good, the wind ruins it.
Honestly, for the next two weeks, there's nothing I'd call a standout. It’s a long, frustrating stretch. Keep an eye on it though; it doesn’t tend to stay this poor for long around here, and the forecasts can change.
Stay patient,
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.
