The Lowdown
Alright folks, Rusty here. Let’s be honest about what’s on offer for the next couple of weeks at Rhosneigr.
The honest truth is, we’ve got a flat spell stretching out ahead of us. There’s nothing really surfable in the first week, and the second week doesn’t look any better. The whole 16-day window is basically a write-off for paddle surfing. The swell energy is pitiful, barely registering a whisper, with the strongest combined energy hitting just 305 (moderate) on Wednesday the 5th of August, but that comes with a 22–25 mph onshore wind, making it a total mess. For a beginner-friendly, fairly consistent break like this, it’s a real bummer.
The most significant swell we see is on Wednesday, August 5th, with a 7 ft SW swell. That’s borderline big for beginners, but it’s accompanied by a strong onshore wind, so it’s going to be blown out and ugly. The period is short at 6 seconds, so it’s just wind chop. The rest of the time, we’re looking at ankle-to-knee high dribble.
Given the persistent onshore and cross-onshore winds, and the fact that Rhosneigr is a beach and reef setup, this looks way more interesting for kite surfing than paddle surfing for the entire forecast period. The combination of moderate onshore winds and weak, choppy waves is a kite surfer's dream, but pure misery on a surfboard.
The water temperature is about average for the time of year, nothing abnormal there.
Honestly, there’s not a single standout window. Don’t even bother checking the forecast until the jet stream shifts. Put the board away and go for a swim.
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.
