The Lowdown

Alright, Rusty here. Let's chew the fat on Larmor Plage for the next couple of weeks. It's a quiet picture, I'll tell ya that. A real slow start with nothing much doing.

There’s a big gap right at the beginning. From now all the way through to the morning of Friday, August 14th, it’s basically flat or junk. Tiny waves and poor winds. Not worth wetting a wetsuit.

Friday morning the 14th is the first chance. Larmor Plage has a clean 3ft swell from the west, with a 9 second period and a light cross-offshore breeze from the northwest. The combined wave energy is moderate at 139, but it’s still just ordinary. A real 'meh' session.

Saturday the 15th morning is similar—3ft from the west, clean, but low energy at 86.

The one that stands out is Friday, August 21st, in the morning. We’ve got a clean 3ft swell from the west-northwest, with a 10 second period. The wind is a solid offshore from the north at 15 mph, which is going to clean everything right up. The combined wave energy is 176 (moderate). It’s not a big swell, but that offshore wind makes it the clear winner for the whole 16-day stretch. The swell direction is a good match for the break. Remember, it’s over a week out, so it’s a promising bet, not a sure thing.

Saturday morning the 22nd of August is a backup. Smaller at 2ft from the west-northwest, but with a light offshore breeze and clean conditions. Low energy at 84.

Right at the tail end, Monday the 24th of August morning, we get a glassy moment. A 2ft swell from the west-northwest, with glassy conditions and barely a breath of wind. Energy is 88, so it’s small, but glassy is glassy. A longboard dream.

So, bottom line: it's a lean couple of weeks. The best bet is that Friday the 21st with the offshore wind. Everything else is small, weak, or messy. Good for a beginner paddle, but not for anyone chasing a real wave.

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.

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.
