The Lowdown
Alright folks, it's Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Well, I gotta be straight with you – this is a tough one. Staring down the barrel of a 16-day outlook and every single session is marked as poor surf conditions. That means there's a big gap right from the start with no real surf to get excited about. We're looking at a stretch of days where the wind and swell just aren't playing ball.
The first few days are a write-off. Sunday the 6th is a mess with a strong 19 mph south wind hitting the coast, making things lumpy and ugly. That carries on through Monday and Tuesday, with a fresh cross-onshore breeze and choppy, lumpy conditions. The swell is a mix of short-period, weak junk, and even when it tries to push up to 5 ft, the wind just ruins it.
We're stuck in this pattern for a while. The combined wave energy does hit a moderate 122 on Sunday morning, but it's paired with a terrible wind. The only real highlight is that the water temperature is about average for the time of year, so you won't need a full winter suit just yet, but it's not going to make the surf any better.
You'll notice a slight change on the 15th of September, a Tuesday. The swell finally pushes up to 6 ft from the SW, and the wind drops to a gentle 9 mph. The combined energy jumps to 209 in the morning and 255 in the afternoon. It's still not great, and the conditions are still described as poor, but it's the first time we see a little bit of potential. September 18th, a Friday, gives us a glimmer of hope with a light 6 mph NW wind and a 5 ft SW groundswell. The energy is moderate at 128, and it's a cross-shore wind, which is the best we've seen. It's still far from perfect, but it's the best looking day in the whole run for a beginner-friendly spot like Rhosneigr.
But honestly, for the bulk of this forecast, the constant onshore wind and short-period swell just aren't going to produce anything you'd want to paddle out for. The setup is more interesting for the kite surfers than us.
This is a real dry spell. It doesn't happen often around here, but when it does, you just have to wait for the forecasts to 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.
