The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this outlook for the next 16 days is a bit of a tough one. We’ve got a long stretch of nothing happening, and then one very specific morning that might just be worth setting an alarm for.

The first real surf recommendation doesn’t appear until Sunday the 23rd of August. Before that, we are looking at a solid 10-day gap of flat, weak, or messy conditions. The wind is mostly cross-on or onshore, and the wave heights barely get a pulse. It’s a real quiet period for the region.

Let’s talk about the one standout. On Sunday morning, the 23rd of August, Rhosneigr finally shows a pulse. The swell will be a clean 5 ft, coming from the south. The period is a short 6 seconds, so it’s windswell, but the real magic here is the wind. It’s forecast to be glassy – absolutely no wind. That’s a massive positive for a spot that can get messy. The water is sitting at 64°F, which is a touch warmer than normal for this time of year, so you’ll be comfortable. The combined energy of all swells is moderate at 171, so there’s some push in the water. It’s a 5 ft swell, so it’s a solid size for the better surfers, but could be a handful for beginners. It’s a fairly consistent break, and with that glassy surface, you’ll be in for a treat.

That Sunday afternoon, the wind swings back onshore though, and the swell jumps to 6 ft with a messy look to it, so the morning is the window.

After that, the following week drops off again into small, choppy, and mostly poor conditions with no real redeeming features. The second week is a write-off, honestly.

So, mark your calendar for the morning of the 23rd. It’s the only real chance for a clean session. The rest of the month is a waiting game.

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.
