The Lowdown
Grab the board, but don’t get too amped just yet—there’s a bit of a wait before anything really fires. The next week is a mixed bag, mostly small and junky, with a couple of windows where the tide and wind might line up for a sneaky session. The real story here is a promising pulse of longer-period swell arriving around Saturday the 13th, but you’ll need to pick your moment carefully. Water’s a touch warmer than normal for this time of year, sitting around 67°, so it’s comfortable out there.
Kicking off Wednesday morning the 9th at Larmor Plage (Morbihan), we’ve got clean conditions with a light cross-offshore breeze and a solid 5ft of west swell. The period is a touch short at 9 seconds, but the energy is moderate (521), so the waves should have a bit of push. It’s a beginner spot, though, and it’s inconsistent, so you might be waiting around for sets. Still, that’s the best of the early week. The afternoon fades fast with the wind picking up.
Thursday is a write-off – tiny 2ft and onshore junk. Friday the 11th looks better on paper with 5ft and a longer 10-second period, but the wind is cross-onshore and bumpy in the morning, and the afternoon gets messy. Not worth the paddle.
Then we hit the gap. Saturday the 12th starts glassy with a small 3ft, surfable but ordinary. Sunday the 13th, the swell bumps up to 5ft in the afternoon with an 11-second period and energy building (960), but the wind is doing everything wrong – strong cross-shore chop. It’s a frustrating tease. That whole stretch from Thursday the 11th through to Tuesday the 15th is mostly poor. You’re looking at a few days with hardly anything worth your time.
Now, the standout – and it’s a conditional one. Wednesday morning the 16th brings a clean, moderate offshore breeze with a 3ft west swell at a better 10-second period. The energy is a bit weaker (196), but the conditions are right. It’s surfable, clean, and the break is fairly exposed to the west, which matches the direction. It’s still inconsistent, so be patient. This is the pick of the bunch for the whole outlook, but it’s not a big wave day.
From there, the second week dies off. Thursday and Friday are small and messy. Saturday the 20th is flat and glassy, barely a ripple. The rest of the period is a slow fade into nothing – tiny waves, onshore breezes, and poor quality. There’s a brief glimmer on Monday the 21st and Tuesday the 22nd with clean, small 2ft and 2ft waves and a longer 11-12 second period, but the energy is weak. For a beginner spot, this is just not worth the trip unless you’re desperate to get wet.
So, bottom line: it’s a lean stretch. The best bet is Wednesday the 16th morning, and even that’s a small, clean mushy day. If you need a fix, get out early, keep your expectations low, and enjoy the water temp.

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.
