The Lowdown
Alright folks, Rusty here. I’ve had a good look at the charts for the next 16 days, and I’ve got to be straight with you: it’s a tough read. We’re in for a long, dry spell with very little to get excited about.
Right now, the water is sitting at 63°, which is a touch warmer than normal for this time of year, but that’s about the only thing that’s working in our favour. The first real chance of a wave doesn’t show up until the 27th of July, and even then, it’s a messy 3ft SW windswell with a short, weak 4-second period. The combined energy is a measly 31, and with a moderate onshore breeze, it’s poor. That sets the tone for the next week.
From the 27th of July right through to the morning of the 8th of August, we’re looking at nothing but poor surf conditions. The swell is tiny, period is short, and the wind is almost always on it or cross-shore. There’s a few days around the 3rd and 4th of August where the wind goes light offshore and the water cleans up, but the swell is only 0.3ft to 1ft. You’d be bobbing around on a lake. It’s a solid 12-day stretch of flat to near-flat conditions.
Things finally change on the 8th of August. Saturday morning brings a pulse of 6ft swell from the west, with a combined energy of 220 (moderate). The period is a weak 6 seconds though, and the wind is light cross-onshore, so it will be lumpy. By Saturday afternoon, the wind picks up to a fresh 19 mph, making it cross-onshore and lumpy. Then Sunday the 9th delivers the biggest swell of the window: 7ft from the WNW on Sunday morning, with combined energy hitting 299 (still moderate). The period is still only 6 seconds, and the wind is a solid 22 mph onshore. This is heavy, messy, and blown out. For experts only, and even then, it’s not pretty. Rhosneigr is a beach break, so with that poor quality and strong wind, this setup looks more interesting for kite surfing than paddle surfing.
The best on offer, if you can call it that, is the morning of the 8th of August. It’s the only time the swell is over 3ft and the wind isn’t howling. 6ft from the west, with a light cross-onshore breeze. It’s not clean, but it’s the least bad option we’ve got. The other slight highlight is the morning of the 6th of August. The swell is a pathetic 1ft from the SW, but the wind is glassy. It’s a flat, clean session for a log or a skimboard, nothing more.
After the 9th, it drops off a cliff again. The 10th and 11th of August are a return to tiny, wind-affected junk. The 11th shows zero energy.
So, to sum it up: 12 days of almost nothing, then a couple of days of messy, blown-out, expert-only swell, then back to nothing. It’s a tough one. If you’re desperate, the 8th of August is the best of a bad bunch, but don’t expect much. The ocean is giving us a rest.
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.
