The Lowdown
Alright, folks, Rusty here. I’ve been staring at the charts for Larmor Plage and, well, we’ve got a bit of a quiet spell to get through before anything worth paddling out for shows up.
The first real glimmer of hope doesn’t appear until the 14th of August, with a couple of days of just barely surfable waves. Before that, we’re looking at a solid 11-day stretch of flat or poor conditions. The wind is mostly onshore or cross-shore, with a slight chop, and the swell is tiny—often under 2 feet. The combined wave energy is weak, hanging around in the double digits (like 52 on the 3rd of August), which tells you there’s hardly any grunt in the water. The water temp is about 65°, which is pretty normal for this time of year.
Friday morning, the 14th of August, is the first time we get a whiff of something. The wind will be offshore from the North at 12 mph, cleaning things up. The swell is still small at 2 feet from the West, with a combined energy of 69, but it’s clean. I’d call it “surfable but very ordinary.” The 17th of August, Monday afternoon, looks like the best of the window. The wind will go glassy—calm, zero wind—and we’ll have a 5 feet swell from the West-Northwest, with a combined energy of 287. That’s moderate energy, and the period is 8 seconds, so it’s a short-period wind swell, but it’ll be clean. The 16th of August, Sunday, has some bigger numbers, with a 7 feet swell on the morning and 8 feet in the afternoon, but the wind is messy and onshore, so it’s not going to be good. The 8 feet swell on the 16th afternoon has a combined energy of 763, which is strong, but with that cross-onshore wind, it’s only for the very experienced or those who don’t mind a nasty chop.
The standout is Monday the 17th of August afternoon. That 5 feet swell from the West-Northwest with glassy conditions is your best bet. It’s a beach break here at Larmor Plage, so with a short period, it’ll be a bit crumbly, but it’s the cleanest surf we’ll see. The 14th of August morning is a second option, with that offshore wind, but the swell is barely a ripple. For beginners, the 2 feet stuff on the 14th might be okay, but anything over 5 feet will be too much. The 7 feet and 8 feet on the 16th are only for the experts.
Crowds can be an issue here sometimes, so keep that in mind for the 17th.
Rusty out.

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.
