The Lowdown

Alright, mate, Rusty here. Let’s break down what’s happening at Larmor Plage.

Right off the bat, we’ve got a bit of a slow start. The first few days are pretty ordinary – a lot of cross-shore wind and messy, weak waves. The water temp is sitting at 66°F, which is pretty normal for this time of year, so no worries there. The real action doesn’t kick in until Saturday, September 5th, and that’s where the standout lies.

Saturday morning, September 5th, is your best bet. We’ve got a solid 5ft swell rolling in from the WNW, with a long period of 13 seconds – that’s proper groundswell energy. The combined energy is a healthy 724 (moderate), and with a light offshore breeze from the north, it’s gonna be clean and lined up. The swell direction is a good match for the optimum SW, so expect some nice, punchy waves. Larmor Plage is a fairly exposed beach, and it’s rated as beginner-friendly, but with this size, it might be a bit much for absolute beginners – more of a fun session for the intermediate crew. Crowds can happen here sometimes, so get in early.

After that, the surf drops off again through the rest of the first week. There’s a bit of a gap with only small, weak, and messy conditions until September 8th. That Tuesday morning, the 8th, brings a 4ft swell from the west with a reasonable 11-second period, light offshore winds from the north, and clean conditions. It’s not the big swell of the 5th, but it’s a solid, fun option for a smaller board.

Then, it’s another quiet spell until September 10th, Thursday afternoon. That session sees a 5ft swell from the WSW, an 8-second period, and a light cross-offshore breeze from the WNW. It’s clean and punchy, worth a look if you’ve got the itch.

Looking further out, September 14th, Monday afternoon, is a real long-range gem. We’ve got a 4ft swell from the west, but with a very long period of 16 seconds – that’s deep ocean groundswell. The combined energy jumps to 1003 (strong), and with light offshore winds, it’s gonna be clean and powerful. This one’s got potential, but it’s far out, so keep an eye on it.

The following morning, September 15th, holds a 6ft swell from the west with a 13-second period, but the wind is cross-shore and a bit messy, so it’s not as clean as the day before.

All in all, the standout is the Saturday morning, September 5th. Get out there for that one. The rest of the window is a mix of average to poor conditions, with a couple of clean but smaller windows on the 8th and 10th. The long-range stuff on the 14th looks promising, but we’ll have to wait and see.

Rusty.

Information about the Larmor Plage Surf forecast

The above surf forecast table for Larmor Plage provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Larmor Plage can be found by selecting the local surf guide option on the grey menu. Our Larmor Plage 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 (Larmor Plage) 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 Larmor Plage 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.
