The Lowdown

Alright, let’s get this sorted. It’s Rusty here.

Honestly, looking at the next couple weeks for Larmor Plage, I gotta level with you: it’s pretty bleak for a while. We’ve got a good stretch of tiny, weak, and mostly poor surf ahead. The first real day that even sniffs at being a surf is Thursday the 20th, and even that’s only just getting to a point where you’d paddle out. Until then, from today through Wednesday, it’s all under 2-3 feet, mostly poor conditions, and not worth getting too excited about. It’s a bit of a drought.

The energy in the water is just weak, too. On the 20th, that combined swell energy finally jumps into the low triple digits (106), which is moderate, and we get a clean morning with a light offshore cross-off wind. The waves are still only 3 feet with a 9-second period, so it’s not going to be a day of barrels. But it’s clean, the wind is kind, and it’s the best we’ve seen so far. Scores are low though, so keep the expectations on the floor.

The next decent window looks to be Friday the 21st morning. Again, nothing big (2 feet), but it’s clean, the period stretches to 10 seconds, and we get that nice NW cross-off breeze. The energy is better (119), which gets my hopes up a little. It’s still a smaller day, but the shape should be way more fun than the mush we’re seeing from the onshores.

After that, it’s another dry spell. From the 22nd all the way to the 28th, we’re back in that poor-to-ordinary zone. The winds get messy, the waves drop off, and it feels like it just never gets its act together. You can see a lot of fresh cross-shore breezes and lumpy chop in that period, which just isn’t fun.

Then on Saturday the 29th, something finally clicks. The morning shows some promise with a 3 foot WNW groundswell, a 10-second period, and combined energy of 131 – the highest we see in this whole window. The wind is a gentle cross-shore, so it won’t be perfectly glassy, but it’s not going to ruin it either. This is the standout, but it’s still just a modest day, a fun, playful longboarder’s wave rather than something that’s gonna have you hooting from the channel. It’s far enough out to be called promising, but not a guaranteed epic.

So, to sum it up: there’s not a whole lot to get excited about, and the best on offer is small and clean on the 20th and 21st mornings, with the 29th shaping up to be the pick of the bunch, though still small. The water temp anomaly is listed as average, so just bring the usual spring suit.

Keep the faith, check back with me later. The ocean’s always got something in the works.

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.
