The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.

Alright, we’re looking at a pretty lean stretch ahead. The next three days are a write-off with messy onshore wind and poor conditions, so don’t bother paddling out. The first real hope comes on Monday, the 31st of August, with a decent 8ft W swell and a 10-second period, but the wind is cross-off in the morning, which will clean things up a bit. The combined energy of all swells directed here is pushin’ a solid 1019 (moderate to strong), so it’s got some grunt, but it’s a bit of a messy beast. That Monday afternoon gets a cross-shore chop, so the morning is your window.

The standout of the whole run is probably Saturday morning, the 5th of September. We’ve got a 4ft W groundswell at 11 seconds, and the wind is a light NNE cross-off, creating clean conditions. The energy is at 446 (moderate) and it’s the only session that gets a nod for “good surf conditions.” It’s not huge, but for a spot that’s been battered by wind, this is the one to circle. The water is around 66°F, which is about normal for the time of year.

The other session worth a mention is the morning of Tuesday, the 1st of September. The swell has dropped to 4ft from the west, but the wind is glassy, dead calm. It’s weak, with only 251 energy, but glassy conditions are rare enough that you might get a few fun ones if there’s any push. It’s a beginner-friendly break, so that’s a plus.

After that, it’s a long, dry spell, with a few days of barely surfable slop and then a run of poor conditions that stretches all the way through the second week. The 4th of September brings a bigger 5ft to 6ft W swell with a long 12-second period, but the wind is messy cross-shore, so it’ll be lumpy. Not worth the paddle.

The 9th of September (Wednesday) morning has a clean offshore wind from the NNW, but the swell is only 3ft and weak. You might get a wave, but it’s a toy surf.

Nothing else in the second week is worth getting wet for. The 12th and 13th of September have clean cross-off winds, but the swell is under 3ft, and the energy is weak. It’s a dead zone.

So, bottom line: forget the next few days. Saturday the 5th morning is your best bet for a clean, fun session on a moderate west swell. Tuesday the 1st is a glassy backup if you’re desperate. The rest is a long, flat wait.

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.
