The Lowdown

Alright, Rusty here, let's talk about what's on offer for the next couple of weeks.

Right, I'm going to be straight with you – the next 16 days at Rhosneigr are looking pretty grim. Honestly, there's a big fat gap with no surf worth talking about. The whole first week, from the 19th of August through to the 26th, is basically a write-off. You're looking at tiny, weak mush with energy levels barely hitting double digits (45) and short, choppy periods. The water is significantly warmer than normal for this time of year, sitting at 65°F, which is a bit odd, but it doesn't make up for the lack of waves.

The only time things even look like they might get interesting is right at the very end of the period. On the 31st of August, Monday afternoon, we get a bit of a pulse. The swell jumps to 5ft from the WNW, with a combined energy of 149 – that's the only time we see a three-digit number in the whole run. That's still pretty weak energy, but it's the biggest the whole forecast. However, the wind is onshore from the WSW at 12 mph, so it's going to be messy. And for the 2nd of September, Wednesday morning, we see a 4ft NW swell with light winds, but again, the period is a short 5 seconds and the energy is only 99. It's a very marginal, short-period wave.

For a beginner spot like Rhosneigr, any swell over 5ft can be a handful, but even that won't be clean. The 5ft on the 31st is the only real standout, and it's only for experts who don't mind a bit of chop. The rest of the time, it's flat. There's nothing to get excited about here. The forecast can always change, but right now, I'd leave the boards in the van.

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.
