The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for the next couple of weeks.
Honestly, if you're a paddle surfer, this is a tough stretch to get excited about. The first few days are a write-off, with strong cross-onshore winds and lumpy, messy conditions. The wave energy is moderate to fairly strong early on, hitting around 868 (moderate energy) on Saturday morning, but the wind just ruins it. We’re looking at a big gap of poor surf until Monday the 31st of August, when things finally start to clean up.
The best window of the whole forecast lands on Saturday the 5th of September. That’s your standout. Head to Larmor Plage (Morbihan) early. We’ve got a clean, cross-off breeze from the ENE at 6 mph, which is a major positive. The swell is a small 3 ft from the W, but it’s got a long 13-second period, giving it some real shape and push. The combined energy is moderate at 381. It’s a beginner-friendly spot, but it is inconsistent, so be patient. The water temperature is 66°, which is normal for the time of year. This is as good as it gets.
The following Monday morning, the 7th of September, also looks promising. Again, clean conditions with a cross-off breeze from the ENE at 6 mph. Swell is 4 ft from the WNW with an 11-second period and a moderate energy of 428. Another solid option if you miss the weekend.
The rest of the period is a mixed bag of small, weak swells and the wind swinging around. There’s a brief clean window on the morning of the 4th of September, but the swell is tiny. The very end of the run, on Sunday the 13th of September, shows a little 1 ft cleanup with a very long 15-second period, but it’s barely surfable.
Rusty, signing off.

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.
Larmor Plage is 5 km (3 miles) from Lorient. If you plan a holiday in Morbihan - Brittany, look for hotels and other accommodation in Lorient. Lorient has rooms for a wide range of budgets as well as car hire and transport links.
