The Lowdown

Alright folks, Rusty here. Gotta be straight with you – the outlook for the next couple of weeks is a tough one to swallow. We’re looking at a long, dry spell with barely a ripple worth paddling for.

Let’s start with the overall pattern. The forecast shows a few pulses of energy pushing through, but the wind is just relentless. It’s either cross-onshore or onshore, and it’s chopping everything to bits. The water is sitting at 63° right now, which is a touch warmer than normal for early September, but that’s little comfort when the surf is this ugly.

We kick off Saturday, September 5th, with a tiny 3ft WSW swell, but it’s a short-period 5 seconds and a moderate cross-onshore from the west at 12 mph. The combined energy is weak (44), and it’s just a choppy mess. Not worth a second look. Sunday the 6th brings a bit more size – 5ft to 5ft from the SSW – but that’s with a fresh breeze at 19-22 mph. The energy jumps into the moderate range (122-156), but the wind is destroying any chance of a clean wave. The onshore wind is just too strong. Into Monday the 7th, we get a tiny 1ft swell with a very long 14-second period in the morning, which is a tease, but it’s onshore and the energy is only 61. The afternoon picks up to 5ft but again, it’s onshore and messy.

The middle of the week doesn’t get any better. Tuesday the 8th has a 6ft WSW swell (energy 199) but it’s cross-onshore with a fresh breeze, and lumpy. The same story continues through Wednesday, Thursday, and Friday – we see moderate energy in the 100-200 range, but the wind is fresh cross-onshore, and the wave comment is constantly “poor surf conditions.”

Things go completely flat by Saturday the 12th. The swell drops to 1ft and 0.7ft, and while the wind finally goes cross-offshore and then glassy offshore, it’s just too small to ride. The combined energy is down to single digits (5 and 1). There’s a glimmer of hope on Sunday the 13th with a glassy 0.3ft, but again, it’s nothing. The 14th through the 17th are more of the same – tiny swells, onshore or cross-onshore winds, and nothing but choppy or lumpy conditions.

Even into the second week, the story doesn’t change. We see a tiny 2ft on the 16th, but it’s onshore with a 4-second period. The energy is never above 17. The last few days of the forecast, from the 18th to the 20th, are essentially flat, with no swell recorded at all.

If you’re looking for a standout, there isn’t one. The best we can say is that the wind does go light and glassy for a very brief window on the 13th and 16th, but there’s no swell to go with it. Honestly, this setup looks more interesting for kite surfing than paddle surfing, given the consistent wind and lumpy water.

For a beginner, be aware that any of the swells over 5ft (like the 5ft and 6ft ones) are going to be too big for you, and the wind will make them even more challenging. The long-period swell on the 7th (14 seconds) and the 20th (14 seconds) could have been good at a point or reef, but the onshore wind ruins it, and the 20th has no swell height anyway.

It’s a blank run, folks. A 16-day gap in quality surf. Sometimes that’s how it goes in this area. Forecasts can change, but for now, the board stays in the car.

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.
