Table - best surf conditions forecast for Rhosneigr over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you. This is a tough one for Rhosneigr. The next 16 days are looking pretty bleak for any decent surf. We’ve got a long stretch of nothing coming up.
For the first week and a half, from Sunday the 12th right through to Friday the 24th of July, it’s basically flat. You’ll see some tiny bumps here and there, with a few 0.3ft to 1ft swells, but the energy is just pathetic – often in single digits (0 to 22). The wind is mostly offshore, which would be great if there was any wave to hold up, but there isn’t. It’s a real tease.
The water is sitting at 62°F right now, which is a touch warmer than normal for the time of year, but that’s small comfort when you’re just bobbing around on a lake.
There’s a glimmer of something on Saturday the 25th, but it’s not for the faint of heart. A new SSW swell shows up, but it’s got a short, weak period (5-6 seconds) and will be blown out by strong onshore winds. By the afternoon, the swell is 6ft with a combined energy of 204 (moderate), and the wind is a fresh 22 mph from the SSW. That’s a messy, lumpy onshore mess. For the experts only, and even then, expect a battle.
The big day for the crew with some nerve is Sunday the 26th. The morning brings a 5ft SSW swell, period 7 seconds, and a solid 205 energy reading. But here’s the catch – the wind is howling onshore from the SW at 22 mph. This is a classic case of “looks big from the car park, but you’ll be paddling into a washing machine.” It’s a strong cross-onshore and messy. If you’re a beginner, stay well away – that’s way over the 5ft mark for you. For the experienced, this is a kite-surfing dream, but for a paddle surfer, it’s a punishment.
The last day of the forecast, Monday the 27th, sees the swell drop back to 3ft with a weak 5-second period and 74 energy. Still cross-onshore and choppy.
So, what’s the best on offer? Honestly, there isn’t a true standout. If you’re desperate for a wave, the early morning of Saturday the 25th sees a 3ft swell with onshore winds, but it’s the only time you’ll see anything rideable. The 26th has the most size, but at the cost of hideous wind. This is a period where the forecast says “stay home and clean the wax off your board.”
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.
