The Lowdown
Alright, let’s get real about Rhosneigr. I’ve looked at the whole 16-day window, and I’ve got to be straight with you – it’s a tough stretch for paddle surfing. The swell is tiny, the wind is mostly messy, and the conditions are just not cooperating. We’ve got a long gap of flat, clean, but useless surf right through to the start of the next week. There’s one little window that might just barely be worth a look, but it’s a long way out.
For the first proper swell, you’d be waiting until the 25th of August. Tuesday morning, we see a 5ft swell from the SSW, with a period of 8 seconds. That’s a moderate 245 combined energy, but honestly, the wind is a cross-shore, so it’s going to be a bit choppy. The water is about average for the time of year, no real surprise there.
The only real standout – and I’m being generous here – is Saturday the 29th of August. It’s a long way off, so don’t book the day off work yet, but the morning looks glassy. The swell is tiny, only 2ft from the SSW, but there’s a 9-second period on it. The combined energy is weak at 75, but with glassy conditions, it’s the only time the report says "surfable waves." It’s a beginner-friendly wave, so if you’re just learning, it might be a fun little paddle. But don’t expect anything epic.
Honestly, for the rest of the run, we’ve got days of flat, clean, but pointless surf, or days where the wind is onshore or cross-onshore, making it a mess. The 1st and 2nd of September look like they’ll be blown out with strong winds. If you’re into kitesurfing, the setup on the 25th might be more interesting than paddle surfing.
So, keep your hopes in check. The forecast can change, but right now, it’s a waiting game.

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.
