Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
To be straight with you, this is a tough stretch. We’re looking at a big ol’ blank run of flat or near-flat conditions for the first week and a half. It’s a real bummer, but it happens. The forecast starts with nothing on the 9th of July and we’re basically staring at a wall of tiny, unridable junk until around the 20th of July. That’s a solid 11-day gap where you’d be better off waxing your board at home.
The first faint glimmer of hope shows up on the morning of the 20th of July at Rhosneigr. A small NW swell pushes in at 4ft, but with a period of only 5 seconds, it’s weak and gutless. The combined wave energy is a measly (59), so you’re looking at short, fat waves. The wind is a clean cross-off from the NNW at 9 mph, which is the only saving grace. It’ll be clean, but it’s really only for beginners or a longboard if you’re desperate. The water is a touch warmer than normal for this time of year.
The 21st of July is similar, with a little less size, and the wind swings around to a messy cross-onshore, chopping it all up. The 22nd of July is even smaller and onshore. By the 23rd of July, the wind is howling from the W at 19 mph, making it a total write-off for surfing – that setup looks more interesting for kite surfing than paddle surfing.
There’s no real standout window here. The best of a bad lot is the morning of the 20th of July at Rhosneigr. It’s clean, small, and weak. If you’re a beginner, it might be worth a paddle. For anyone else, keep your expectations on the floor. Forecasts can change, but right 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.
