The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Rhosneigr over the next couple of weeks.
Truth is, it’s a flat spell. We’re looking at a long stretch of tiny, weak, and mostly messy conditions. The first week and a half is just not going to deliver any real surf. From Thursday 30th July right through to the end of the first week of August, the energy is basically non-existent. You’ll see a few tiny bumps here and there, but they’re all under 2 ft with short periods under 4 seconds, and the wind is often cross-shore or onshore, making it a choppy, frustrating paddle. The combined energy values are pathetic – a measly 5 to 16 (weak) – just not enough to push a decent wave. There’s a glassy moment on Sunday morning 2nd August with a tiny 0.7 ft wave, but it’s too small to do anything with.
The second week shows a glimmer of hope for the patient surfer, but it’s still marginal. The key change is that the wind turns offshore for a long stretch from Monday 3rd August right through to Tuesday 11th August. The wind comes from the ENE or NE, keeping the surface clean. But the swell is still tiny – mostly 0.3 ft to 1 ft – with a few sessions showing a longer period around 9 to 12 seconds. This means the waves that do show up will be clean and a bit more lined up, but you’ll be scratching for a ride. The combined energy values are still very low, ranging from 1 to 12 (weak). The best of the clean windows might be Thursday afternoon 6th August or Monday morning 10th August, with a gentle offshore breeze, but you’d be on a log or a longboard, and you’ll still be waiting a long time between sets.
The standout, if you’re desperate, is the few glassy sessions on Sunday 2nd August morning and the light rain days on Wednesday 5th August. The water temperature is about average for the time of year, nothing unusual to report.
If you’re looking for a proper surf, this isn’t the window. It’s a kiteboarder’s session with the offshores, but for a paddle surfer, it’s a stretch. The break is a fairly consistent spot, but it tends not to stay this poor for long, so hang tight. Forecasts can change, but for now, it’s a quiet run.
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.
