The Lowdown

Alright, folks, it’s Rusty here. I’ve had a good look at the charts for our patch, and I’ve got to be straight with you – it’s a grim picture. The next two weeks are pretty much a write-off for Rhosneigr. There’s nothing on offer that I’d recommend paddling out for. The whole forecast period, starting now and running through to the 21st of September, is a long, flat, and messy run. Every single session comes back as poor surf conditions, so we’re looking at a solid gap with no real surf to speak of.

Let’s break it down anyway, because that’s what we do. The water is sitting at 63°F for the first mention, which is a touch warmer than normal for this time of year. Not that it’ll matter much when you’re not surfing.

We start off Sunday the 6th with some small bump, but a strong southerly breeze is making a mess of it – 5 ft to 5 ft of short-period slop with weak energy (118 and 168). The wind is cross-on and the wave comment says it all: poor. Monday the 7th is worse, with a tiny 1 ft long-period swell on the morning that’s blown out and an onshore mess in the afternoon. Tuesday the 8th sees the swell bump up to 6 ft from the west, but it’s accompanied by a fresh cross-onshore wind and energy readings in the moderate range (182 and 178). Still, it’s a lumpy, poor quality mess.

Wednesday the 9th morning has the biggest combined energy we’ll see at 235, with 6 ft from the northwest and a cross-shore wind. That might sound interesting, but the period is a weak 6 seconds and the description is “fresh cross-shore with lumpy cross-chop.” Not the kind of waves you want to be out in. It drops off sharply that afternoon. The rest of the first week is the same story: onshore winds, weak swell, and consistently poor conditions.

Moving into the second week, it doesn’t get any better. From the 14th of September onward, the swell drops to almost nothing – we’re talking 0.3 ft to 2 ft of weak, short-period slop with energy readings barely reaching double digits. The wind is howling from the west and southwest, often at strong breeze or near gale force, which just makes everything choppy and unrideable. The final few days from the 18th to the 21st offer a slight pulse of 5 ft to 6 ft on the 18th, but it’s accompanied by strong winds and messy conditions again, with energy in the moderate range (159 and 183). It’s still poor.

Honestly, for a spot like Rhosneigr, which is a beginner-friendly, fairly consistent beach break exposed to the southwest, this is a real bummer. There’s simply nothing here. If you’re looking for something to do, the wind is strong and the waves are messy, so this setup honestly looks more interesting for kite surfing than paddle surfing right now. Keep the board in the car, check the charts again in a few days, and hope the forecasts change. That’s all I’ve got.

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.
