The Lowdown

Alright folks, it’s Rusty here, and I’ve got the full skinny on what’s coming up for Rhosneigr over the next couple of weeks. Grab a coffee, because we’ve got a pretty dry stretch to get through before we see any real hope.

First off, I’ve gotta tell you, the water temperature is sitting at 63°, which is a touch warmer than normal for this time of year. That’s a nice little bonus, but it’s not going to help the waves much.

Right now, we’re looking at a long, quiet run. The first proper surfable day doesn’t even show up until Monday, the 14th of September. That’s a big gap of over a week with nothing but crummy, blown-out, and tiny surf. The early days are a write-off: strong onshore winds, messy conditions, and poor surf quality across the board. Even when the swell bumps up a bit, like on Tuesday the 8th with some 8ft swell from the WSW, the wind is howling at 28 mph right onshore, making it a total mess – more of a kite-surfing day than a paddle-surfing day.

So, what’s the best we’ve got? Honestly, there’s only one real standout, and it’s a late one.

Monday, 14th September – Morning
This is your best shot. It’s not big, but it’s clean. We’ve got 4ft of swell from the WSW, and the wind is a flat-out glassy calm. The combined swell energy is weak (66), but that glassy wind means the surface will be like a mirror. It’s a beginner-friendly height, and for a spot that’s “fairly consistent,” this is the one morning to get out. The sets will be a bit short and weak, but it’ll be clean, and after a week of nothing, that’s a win.

After that...
The afternoon of the 14th gets messy again with onshore wind, and the 15th brings back the cross-onshore chop. So, if you’ve been waiting, that Monday morning window is the only real call. It’s a sniff of hope in a bleak forecast.

Stay tuned, forecasts can change, but for now, it’s a long wait for a short, clean window.

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.
