The Lowdown

Alright folks, Rusty here. Let’s get into it for Rhosneigr.

Honestly, the next couple of weeks are a tough watch for the paddle crew. We’re looking at a long, dry spell of poor surf conditions that stretches from Saturday the 18th of July right through to the end of the month. The water is sitting at 63°, which is much warmer than normal for this time of year, so that’s a nice touch for a paddle, but there’s just no energy in the water to work with.

From Saturday the 18th, we’ve got tiny 0.3 ft swell with a long 11-second period, but it’s coming from the S and SW while the wind is cross-off from the NNW. It’s clean, but the combined energy is barely a whisper at 6, so it’s flat. That pattern of small, clean but useless surf continues through the weekend and into the start of the week.

We hit a total dead zone from Monday the 20th of July through to Friday the 24th of July. That’s five days straight with zero swell height and zero energy. The wind is clean, but you could water-ski across the bay. It’s a proper blank run.

Friday the 24th sees a tiny 0.3 ft, 13-second pulse from the S, but the wind switches to a light cross-onshore, then onshore, and the energy is still only 3. That’s not a surfable option.

The last few days of July and the first of August try to send a little more size, but the quality is poor. On Saturday the 25th, we get 2 ft to 3 ft of short-period, 4-second wind swell from the WSW, but it’s onshore and lumpy with 15–22 mph winds. The energy jumps to 27, but it’s a messy, choppy mess. That trend continues right through to Thursday the 30th of July, with waist-high slop, onshore winds, and energy figures from 19 to 88. The wave comment says “poor surf conditions” every single time. For a beach-and-reef setup like Rhosneigr, this is looking more interesting for kite surfing than paddle surfing, to be honest.

There is a small glimmer on the very last day of the forecast. On Friday the 31st of July, we get 1 ft to 2 ft of clean, moderate offshore wind from the NE, with a 6-second period from the SW. The energy is only 11 to 16, so it’s tiny, but it’s clean. That glassy morning on Sunday the 2nd of August, with 1 ft and a 3-second period, is also clean, but the energy is a flat 2. None of this is a standout.

The only real standout in this entire 16-day window is the promise of a clean, offshore morning on Friday the 31st of July. The wind will be moderate offshore from the NE, which is great for the break at Rhosneigr, and the swell is a tiny 1 ft from the SW. It’s not going to be a barnstormer, but if you’re desperate for a log or a longboard, that’s your window. The water is still unseasonably warm, so you won’t need a thick suit.

For the rest of it, it’s a long, flat, poor stretch. Don’t hold your breath.

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.
