The Lowdown

Hey, it's Rusty. Let's have a look at what we're working with here at Rhosneigr. I gotta be straight with you—this 16-day run is looking grim. There's a big gap of quiet before we even see a whisper of swell, but the whole window is pretty much a write-off. Water temp is about 63°F, which is a touch warmer than usual for this neck of the woods.

So, Friday the 11th of September we get a tiny 0.6 ft wave from the southwest, but that moderate cross-shore wind just makes it choppy and unrideable. Forget it.

Saturday the 12th is the only time the swell gets any size, jumping to a solid 7 ft from the southwest. But a strong south-southwest wind is blowing straight onshore. The combined energy is moderate (331 in the morning, 352 in the afternoon), meaning there's plenty of power, but it's all blown out and messy. This is 100% a big, dangerous, and sloppy day for experts only. Beginners, don't even think about it. The report says "poor surf conditions" for a reason.

Sunday the 13th drops right back to a weak 0.7 ft, with the wind still onshore and lumpy. Not worth getting wet.

The whole middle of the month just drags on with small, poor-quality, wind-affected waves. Monday the 14th has a 2 ft swell, but it comes with a fresh onshore breeze and a lumpy texture. Wave energy is moderate (166), but the quality is just gone.

We then hit a flat spell from about Thursday the 18th through the weekend with almost nothing rideable.

Saturday the 19th of September shows a bit of a pulse to 2 ft from the southwest, with moderate energy (237). But again, the wind swings onshore from the south-southwest, creating a moderate cross-onshore chop. The report still says "poor surf conditions." The pattern doesn't break.

Then from the 22nd of September onwards, it's completely flat. The 22nd, 23rd, 24th, and 25th show zero wave energy and strong, messy onshore winds. The very last day of the forecast, September 26th, shows a tiny 0.9 ft wave, but it's still blown out by a fresh onshore wind.

There is no standout day. Not one. This is a classic blank run for this area. It's a tough pill to swallow, but the wind is wrong and the swell is wrong. Sometimes a coast just shuts down for weeks. Keep the board in the bag and hope the forecasts change.

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.
