The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks. I gotta be straight with you – this outlook is a bit of a flat spell, so don’t get your hopes up for any barrels.

First up, the water temp at the main spot is sitting at 63°, which is a solid 4° warmer than usual for this time of year. That’s noticeably warm, you might get away with a springsuit for a dawny.

The 16-day window starts real quiet. For the first week, from Friday the 17th right through to Thursday the 24th, it’s practically a write-off. We’re looking at a long stretch of wave energy that’s barely a whisper, with values like 7 and 10 (weak energy) on the combined scale, and most days showing zero energy. The swell is tiny, mostly 0.3ft to 0.7ft, with a short, weak period. The wind is mostly cross-off from the north, so it’s clean but there’s just nothing to ride. Don’t bother paddling out.

Around Friday the 24th, we get a tiny pulse of 0.3ft southerly swell with a long period of 13 seconds, but the energy is still only 3 (weak). It’s clean with light winds, but it’s barely a ripple. The same goes for Saturday the 25th and Sunday the 26th – still tiny, with onshore winds making it choppy and messy. Not worth it.

The following week doesn’t get much better. From Monday the 27th to Thursday the 30th, it’s mostly flat again with onshore winds, some fresh breezes, and a few readings of 0.3ft to 0.7ft of short-period slop. The energy is almost non-existent, with values of 1 and 3 (weak). Don’t expect any waves worth paddling for.

Now, the only real glimmer in this whole forecast comes right at the very end. On Friday the 31st of July, the morning shows a bit of hope. The wind is glassy from the east, a light 3 mph, and the swell is 1.0ft from the SSE. The period is a short 4 seconds, so it’s windswell, but the glassy conditions mean it’ll be clean. The combined energy is still only 5 (weak), but for a longboard or a foamie, you might catch a tiny knee-high wave. The spot (Rhosneigr) is a beginner-friendly, fairly consistent beach break, and it’s exposed to the SW, so this little SSE pulse is a bit off its optimum, but with glass, it’s the best we’ve got.

Then into Saturday the 1st of August, the swell tries to pick up a bit. The morning has 1.0ft from the SSE, still short period, with clean cross-off wind. The afternoon is where it gets a touch more interesting: 2ft from the SSW with a 4-second period, and the combined energy jumps to 16 (still weak, but the highest of the whole run). The wind is a light cross-on from the WNW, so it’ll have a bit of texture. This is the standout of the whole outlook. It’s not big, and it’s not powerful, but it’s the best on offer. For a beginner-friendly spot like Rhosneigr, this small, cleanish swell is manageable. Because it’s over the 5ft mark? No, it’s well under, so it’s fine for all levels. The short period (4 seconds) means it’ll be a bit crumbly and won’t have much punch – best on a log.

So, to sum it up: the whole 16 days is a flat to tiny period. The only day worth a look is Saturday the 1st of August for a few small, cleanish waves. Don’t hold your breath for the 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.
