The Lowdown
Alright folks, Rusty here. Let’s break down the surf at Larmor Plage.
First thing, the water’s running about 66°, which is a touch warmer than average for this time of year – not a big deal, but nice when you’re sitting in the lineup.
The next few days are a mixed bag. The real window opens up Saturday morning, September 5th. We get a pulse of groundswell from the WNW, hitting 4ft with a nice long 12-second period. The energy is solid (511) and the wind is light from the ENE, putting it cross-offshore. That means clean, lined-up waves. It’s the standout of the whole forecast, but keep in mind this spot is inconsistent – it can be fickle, but when it’s working, it’s worth it. Saturday afternoon the wind swings onshore, so get out early.
Sunday morning September 6th is a washout – small, weak, and choppy. Most of the following week is the same story. We get a lift on Monday morning September 7th with the swell pushing 5ft from the W and a very long 14-second period. That’s proper groundswell energy (832), and if you find a bank that holds it, it’ll be fun, but the cross-shore wind will put a bit of chop on the face. The afternoon gets bigger at 6ft, but the wind cranks to 25 km/h from the WSW, making it a messy, blown-out mess. Those bigger days are for experienced surfers; beginners will find it too much.
The rest of the first week and into the second week is pretty grim. Poor surf, small waves, or strong winds. There’s a small window on Wednesday morning September 9th with 3ft and light WNW winds, but it’s ordinary. The same goes for the September 12th weekend.
Now, looking further out, around September 18th (Friday) and 19th (Saturday), we see a bit of a pulse again. It’s a solid 6ft from the WNW on the 18th with moderate energy (962), but the wind is a strong offshore from the NE, which cleans it up. The period is 10 seconds, so it’s not the long grinder you’d want for a point break, but it’s onshore for a beach break. The 19th drops back to 4ft, though the period stretches to 11 seconds, with clean conditions. That Saturday afternoon has nice energy (520) and good wind, but it’s still a long-range forecast, so keep your fingers crossed.
Honestly, if you’re keen, the best bet is the Saturday morning session on September 5th. After that, you’re waiting for the second week, and that’s a gamble. The setup is more interesting for a kite surfer on those windy, lumpy days than for a paddle surfer.

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.
