The Lowdown

First up, we’re looking at Larmor Plage (Larmor-Plage). The water’s sitting at 19°, which is a touch warmer than normal for this time of year – nice, but not crazy. The early part of the run is pretty flat and uninspiring. Monday morning the 14th has a little 0.9m of west swell, but it’s weak, with only 180 units of energy behind it. It’s surfable for a beginner, but there’s no push. The wind is light offshore though, so it’ll be clean – glassy even. If you’re desperate for a paddle, that’s your window, but I wouldn’t clear my schedule. The afternoon goes downhill with a cross-onshore breeze, and Tuesday the 15th is even smaller, just 0.7m and dropping. The morning is clean but tiny; the afternoon gets a bit more size (1.2m) but it’s blowing 30 km/h from the northwest – clean but chunky, not great.

The gap from Tuesday until Wednesday morning is a bit of a lull. Then Wednesday the 16th starts to pick up a little – 1.5m early, but still not great. The afternoon is where the first real nod comes: 1.6m of WNW swell, period 10 seconds, and the wind swings offshore. That’s clean, pushy, and the energy jumps to 482 units. It’s not huge, but it’s decent. Thursday the 17th though, that’s a stormy mess – cross-shore winds, lumpy, and the swell gets a bit jumbled. Not worth it.

Now, Friday the 18th morning – that’s your first true standout. The swell jumps to 1.7m from the west, period 16 seconds, and the energy is massive – 2150 units. That’s a proper groundswell, and the wind is light offshore. This is the best grooming you’re going to get all window. The period is long, so it’ll be bowly and powerful at a beach break like this – maybe a bit straight-up, but there’s enough push. Experienced surfers will have a ball. The afternoon Friday is bigger – 1.8m – but the wind swings cross and it gets lumpy, so that morning is the call.

The weekend is a letdown after that. Saturday the 19th and Sunday the 20th – small, weak, cross-shore winds. Nothing doing. Monday the 21st morning brings a little life back – 1.2m WNW, period 14 seconds, and light offshore east-northeast wind. The energy is 611 units, so it’s punchy enough for a clean, fun session. That’s your second best window. The afternoon goes onshore and messy though.

Then we hit a real flat spell. Tuesday the 22nd through Thursday the 24th – tiny surf, 0.5m to 0.9m, mostly clean winds but no power. You’re looking at a multi-day gap where you’d be better off checking the tide pools. Friday the 25th morning, the swell comes back up to 1.6m – west swell, period 15 seconds, with an east-northeast cross-offshore wind. That’s clean and has some punch – 1181 units. But the rating is marginal, possibly due to tide. The afternoon gets cross-shore and messy.

The real kicker is Sunday the 27th. Morning sees 2.3m of west swell, and by the afternoon it’s 2.5m – that’s serious size. The period drops to 10 seconds, so it’s not a clean groundswell – more of a windswell. The winds are onshore from the south-southeast, which will make it lumpy and raw. That’s big, but gnarly. Monday the 28th morning is even bigger – 3.0m – but again, onshore and stormy, with rain. This is too big for beginners, pushing into expert territory. If you’re not solid, stay well away. The afternoon has 35 km/h cross-onshore winds, so it’s a full-on mess.

After that, it fades fast. Tuesday the 29th drops back to 1.6m, but it’s cross-shore and lumpy all day. Not worth it. The run ends with small, weak surf and poor conditions.

So, to sum it up: Friday the 18th morning is your best bet – clean, powerful, proper groundswell. Monday the 21st morning is a good second – smaller but still clean with a nice period. The big stuff on Sunday/Monday is for experts only, and even then, the winds are against you. The flat spell mid-week is real, so plan around it.

Rusty out.

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.
