The Lowdown
Right, let’s have a look at what’s cooking for Llandudno over the next couple of weeks. It’s a mixed bag, to be honest. There’s some proper swell on the way, but the wind’s going to be a bit of a pain for a good chunk of it. The standout moments look like they’ll be when a solid southwest groundswell lines up with lighter winds or that magic glassy calm. The water temp is pretty much where you’d expect it to be for this time of year, nothing too wild there.
We kick off Friday the 11th with some swell, but that southeast wind at 19 mph is making it a bit of a scratchy affair. It’s a cross-off, so it’s not totally horrible, but those 6 ft waves from the WSW (12 second period) are just not cooperating with the tide or conditions. The energy’s there, but it’s not really happening for us.
Saturday the 12th sees the swell building a touch, with 7 ft to 8 ft from the SW. The period jumps to 15-16 seconds on the afternoon session, which is proper long-period groundswell. But again, that southeast cross-off wind is fresh, so it’s going to be bumpy. The energy’s getting real strong (2003 and 3878), but it’s not clean enough to get excited about.
Now, Sunday the 13th morning is where it starts to get interesting. The wind drops to a light 6 mph from the ESE, still cross-off. The swell is a solid 7 ft from the SW with a 14-second period. The combined energy is 2236, so there’s plenty of power. This is the call for the experienced crew – it’s going to be clean and powerful at Llandudno. The afternoon hangs on but gets a bit cross-chop.
Monday the 14th and Tuesday the 15th are write-offs. A strong northerly wind whips in at 22 mph, just destroying the surface. We get some lumpy cross-chop, and the swell directions are all over the shop. Not worth paddling out for.
There’s a bit of a bounce-back on the 16th and 17th, with clean cross-off winds, but the swell is shorter period and the conditions are still marginal. It’s surfable for those who are keen, but nothing to write home about.
Then we hit Friday the 18th of September – and this is the absolute standout. The morning is glassy. Dead calm. The swell is a nice 7 ft from the southwest, with a 13-second period. The energy is at 1908. This is the best conditions you’ll see in the whole run. For the strong intermediate and expert surfers, this is the session. Expect clean, powerful lines rolling into Llandudno. The afternoon gets a light SSE breeze, still cross-off and clean, but that morning glass is the one to chase.
Saturday the 19th is also very strong, with a light cross-off breeze and a 6 ft to 7 ft SW groundswell (14-15 second period). It’s going to be clean and fun, but not quite the perfection of Friday morning.
The following week (20th to 25th) is a bit of a mixed run. We get some ok windows on the 20th, 24th and 25th. The 24th morning looks clean again with a light ESE breeze and a 7 ft SW swell at a nice 14 seconds – that’s a solid session for sure. Friday the 25th morning is another glassy one, calm winds, with a 6 ft SW swell. The crowd situation at Llandudno can be an issue, it often gets busy, so for those glassy morning windows, get in early.
Overall, the swell ticks all the boxes from the southwest, which is Llandudno’s best direction. The first real gem is that Friday the 18th morning. The second is the 24th and 25th mornings. The rest of the time the wind is just too strong in the wrong direction to make the most of the good swell that’s coming. For the kite crew, those days with the strong cross-off winds and solid swell will look pretty tasty, but for paddling, you want those glassy windows.

Information about the Llandudno Surf forecast

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 Llandudno 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.
