The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on offer for Rhosneigr over the next couple of weeks.

Straight up, I gotta be honest with you – it’s a grim picture for the next week and a half. The surf is pretty much flat to tiny, and when there is a bit of height, the wind is just ruining it. We’re looking at a long, dry spell with no real recommendations until the 17th of September.

For the first week, from the 5th right through to the 16th, it’s a write-off. Wave heights are barely a ripple, mostly under 3 ft, and the wind is constantly cross-onshore or onshore, making everything choppy and lumpy. The combined energy is weak, so there’s just no power in the water. You’ll be doing more floating than surfing. The water temp is sitting at 63°F, which feels a touch warmer than normal for this time of year, but you won’t care because you’ll be sitting on a flat board.

The only glimmer of hope comes on the 17th of September. The morning looks like a genuine standout. We’ve got a 5 ft swell rolling in from the West, with a period of 6 seconds. The wind is a clean offshore from the NE, blowing at just 3 mph. That’s about as good as it gets for wind here. The combined energy is moderate, meaning there’s actually some push. The afternoon is still clean, with a 4 ft swell and 6 mph offshore winds. For a beginner spot, this is about as good as it’s going to get. The waves will be clean and rideable.

After that, the 18th and 19th see the swell stick around at 5 ft and 5 ft, but the wind swings onshore or cross-onshore, so it’ll get messy again. A real shame, because there was a good window.

So, circle the 17th of September. That’s your one true standout. Go early, enjoy the clean conditions, and make the most of it before the wind turns.

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.
