The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this forecast for the next couple of weeks is a tough one to write. We’re looking at a long stretch of tiny, weak surf with mostly messy wind. Let’s get into it.
Right from the start, we’re in a flat spell. The first recommendation doesn't come until Sunday, August 2nd, and even then, it’s barely a ripple. For the first few days, through Thursday, Friday, and Saturday, the waves are small and the wind is all wrong – cross-shore and onshore breezes messing up what little bump there is. It’s a proper blank run for paddle surfing. If you’re a kite surfer, the consistent cross-shore winds and chest-deep water might look like a fun playground, but for the rest of us, it’s a hard pass.
When we finally get to Rhosneigr on Sunday morning, August 2nd, we’re looking at a glassy 1ft swell out of the SW. It’s basically flat with a tiny bump from a 4-second period. Not worth wetting a wetsuit for.
There’s a glimmer of hope mid-week. By Tuesday, August 4th, we get a couple of clean, offshore mornings with winds out of the ENE. The waves are still tiny at 1ft, but the conditions will be glassy and clean. If you’re desperate to stand on a board and feel the water, the Tuesday morning session is your best bet for a clean, fun paddle.
After that, we slip back into the doldrums. The second week is a washout, with barely any swell and onshore winds dominating. The only thing worth noting is on Friday, August 14th, with clean 2ft sets from the WNW – period is a short 4 seconds though, so it’ll be lumpy and weak.
Honestly, this is a quiet period. We’re in a seasonal lull, and the forecasts can change, so don’t lose hope entirely. But for now, the waves are small, inconsistent, and mostly messy. Keep an eye on the horizon.
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.
