The Lowdown

Alright lads, Rusty here. Let’s break down what’s happening at Rhosneigr over the next couple of weeks.

To be straight with you, this is a grim outlook. The entire 16-day window has nothing worth paddling out for. There’s a bit of swell early on, but the wind is always onshore or cross-onshore, making it a lumpy, messy deal. The water is about 63°F, which is a bit warmer than normal for this time of year, but that’s the only good news.

Starting Wednesday the 2nd, we’ve got a weak SSW swell around 4ft, but a fresh 35 km/h SSE wind has it cross-on and choppy – total junk. That afternoon, the wind goes onshore from the SSW, and the swell nudges up a bit, but it’s still poor. Thursday the 3rd and Friday the 4th are more of the same: onshore winds, lumpy conditions, nothing to get your hopes up.

By Saturday the 5th, the swell collapses to about 2ft, and the energy is pathetic (28). It’s small and choppy. Sunday the 6th is much the same – tiny, onshore slop. Monday the 7th sees a pulse in the afternoon with a 6ft SW swell and moderate wind, but it’s still onshore, and the wave comment says “poor surf conditions.”

The second week doesn’t deliver. From around Tuesday the 8th to the end, we’ve got strong cross-offshore breezes that clean the surface but kill the swell completely. By the 10th, we’re looking at 0.6ft or less. On the 14th, the wind goes cross-off from the NNW, and the water is clean, but the swell is only 4ft with weak energy (93). It’s a long paddle for a tiny wave.

There’s no standout day. The swell is too small, the wind is wrong, and the energy never gets strong enough to save it. If you’re itching for a session, maybe the 14th afternoon might give you a clean, tiny wave, but honestly, I’d wait. Forecasts can change, and it doesn’t usually stay this flat for long, but for now, keep the board in the garage.

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.
