The Lowdown

Alright, let’s have a look at what’s on the cards for Rhosneigr over the next couple of weeks.

Honestly, I’m looking at this and it’s a bit of a tough one. The whole 16-day window is pretty quiet. There’s no real stand-out swell to get excited about, and the wind is mostly working against us. The combined swell energy values are tiny – we’re talking single-digit and low two-digit figures for most of the run, which is about as weak as it gets. The water temperature is sitting at 62°, which is a touch warmer than normal for this time of year, but that’s small comfort when there’s hardly a wave to be had.

The first real chance of anything rideable doesn’t show up until Wednesday morning, the 5th of August. We get a bit of a push of swell from the west, 6ft, but it’s coming with a short period of 6 seconds and a fresh cross-onshore wind from the west at 22 mph. The combined energy climbs to 207 (moderate), but the “poor surf conditions” tag tells you everything. It’s going to be lumpy and messy. That afternoon the swell drops off to 4ft and the energy falls back to 97, so not much better.

The wind continues to be a problem for the rest of the week. Thursday morning, the 6th, has a cross-shore wind from the WNW at 16 mph, with 4ft swell from the NW and energy at 122 (moderate), but it’s still described as poor and choppy. There’s a brief moment on Thursday afternoon with an onshore wind and tiny 1ft swell, but it’s not worth paddling out for.

We get a couple of glassy mornings on Sunday the 9th and Monday the 10th, but the swell is practically non-existent – 2ft and 0.3ft respectively. You’d be floating around on a lake. The glassy conditions are a major positive, but with no wave energy, it’s just a nice day to sit on the beach.

There’s a gap of a few days after that with absolutely nothing. Then, towards the end of the run, on Monday the 17th of August, we see a small bump in the afternoon – 4ft from the SW with a period of 5 seconds and onshore wind. The energy is a weak 51. It’s not good, it’s just not completely flat.

The only break on offer is Rhosneigr itself. It’s a beginner-friendly spot, fairly consistent in terms of it breaking, but the conditions just aren't lining up. For a spot that’s exposed to the SW, we’re getting the swell direction right, but the wind is almost always cross-onshore or onshore, ruining the shape. For a couple of days in the middle of the second week, like the 15th and 16th of August, the swell is either too small or the wind is too strong. It’s a real frustrating run for the Anglesey coast.

Truth is, there’s nothing here worth getting out of bed for. We’ve got a long, flat spell ahead. Keep an eye on the long-range forecasts, as things can change quickly, but for now, it’s a case of dusting off the longboard and hoping for a miracle.

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.
