The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for Rhosneigr. There's a real flat spell on the horizon, so don't be in a rush to grab your board.
For the first week and a half, from Monday the 10th right through to the 22nd of August, it's a total bust. We're looking at a long stretch of tiny, weak waves that aren't worth the paddle. The swell energy is mostly in the single digits, with a few days barely cracking 20 or 30 (that's a combined energy of 2 to 27). The winds are all over the place, but mostly cross or onshore, which just messes with what little bump there is. There's a couple of days, like the 16th, where it goes glassy, but with no swell at all, it's just a flat, pretty lake. Not a thing to ride.
Now, the end of the forecast period starts to show a bit of life. On Saturday the 22nd, the swell starts to build a little, with a 4ft S swell, but it's got a short period of 5 seconds and a cross-onshore breeze. The energy is picking up though (94). On Sunday the 23rd, we get a bit more size, around 4ft from the WNW (101 energy), but again, it's short period and cross-onshore. The real kicker comes on Sunday afternoon the 23rd, with a 6ft NW swell. That's a moderate energy swell (278), but it's a short period windswell, and the wind goes straight onshore from the SW. It's going to be a bumpy, blown-out mess. For a beginner spot, anything over 5ft is already getting too big, and 6ft with onshore wind is just ugly. For the more experienced, the 8ft line isn't hit, but the quality is poor.
Honestly, the only thing that might be worth a look is if you're a local who knows the bank, and you can get out very early on the 23rd before the wind really gets up. Even then, it's a gamble. For the rest of the time, the setup here is more interesting for kite surfing than paddle surfing. I'm sorry to be the bearer of bad news, but the forecast is what it is.
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.
