The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you – this is a tough one to write. We’ve got a full 16-day window and honestly, there’s not a single moment where I’d tell you to grab your board and get excited. The surf is basically flat or junk for the whole run.
Let’s start with the first few days. From Sunday the 19th right through to the morning of Thursday the 23rd, the swell is practically non-existent. We’re talking wave heights of 0.3 ft at best, with extremely weak combined energy (just 2 for the most part). The wind is cross-off a lot of the time, which would be clean, but there’s nothing to ride. It’s a flat spell.
Late on Thursday the 23rd, we get a tiny pulse – 1.0 ft from the WNW, but with a period of only 3 seconds. That’s pure wind chop, and the energy is still pitifully low (2). It’s a no-go.
Friday the 24th brings a bit more period – 13 seconds from the south, but the height is still 0.3 ft. The energy creeps up to a measly 3 or 4. Honestly, you’d be looking at a lake.
The weekend of the 25th and 26th sees a slight bump, with heights up to 3 ft from the NW, and the combined energy finally reaches 43 on the Sunday morning. But the problem is the wind. It’s cross-on or onshore, with moderate breezes, making it choppy and messy. The period is short – 4 to 5 seconds – so the waves are weak and crumbly.
The following week, from the 27th of July into early August, it’s more of the same. We see heights around 1 ft to 2 ft, and the energy occasionally hits 50 on the 30th of July. But the wind is never your friend. It’s either cross-on or onshore, often fresh and lumpy, making for poor surf quality. The water temperature is 63°F, which is a notable 4°F warmer than usual for this time of year, so at least you won’t be cold while you’re sitting there watching nothing.
The last few days, from the 1st of August onwards, the swell just dies again. Flat, clean, but flat.
So, what’s the verdict? There is no standout. There is no best day. This is a blank stretch. With Rhosneigr being a fairly consistent spot normally, this is a rough patch. The best I can say is that if you’re a kitesurfer, the wind is consistent enough on some days (like the 30th and 31st) to get you going, but for a paddle surfer, leave the board at home. Forecasts can change, but right now, it’s a wait-and-see situation.

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.
