The Lowdown

G’day, Rusty here. Let’s be straight with you. The next couple of weeks are a real mixed bag, and for the most part, it’s going to be a waiting game. There’s a proper pulse of energy building for the end of the month, but we’ve got a lot of flat, weak days to get through before that happens.

Right now, the surf is pretty ordinary. This Friday morning at Larmor Plage (Morbihan), we’ve got a clean-looking 3ft of west swell with a 9-second period, and a gentle offshore breeze. It’s rideable, but it’s small and the energy is weak, with the combined swell energy sitting at only 109. The water temp is 68°, which is a touch warmer than normal for this time of year – nice, but nothing crazy. It’s a beginner-friendly wave, so if you’re just getting your feet wet, it’s an option, but don’t expect any heroics.

The weekend is flat and messy. Saturday and Sunday mornings have a bit of knee-high chop, but the afternoon winds swing onshore and just ruin what little shape there is. We’re looking at a few days of nothing really worth paddling out for. The waves drop off to almost nothing by Monday and Tuesday, with clean conditions but no swell to speak of. This quiet spell stretches on for a good while.

We do get a few tiny pulses mid-week, like Wednesday afternoon with a clean 3ft, but it’s still weak and inconsistent. Honestly, for the next eight or nine days, you’re better off finding something else to do. The ocean is basically taking a breather.

Now, the light at the end of the tunnel. The last couple of days of the month, from the 28th of August onwards, things get properly interesting. There’s a solid groundswell on the way, but it’s for experienced surfers only. On the 28th, we’re looking at 10ft of west swell, with a period jumping to 11 seconds, and the combined energy is through the roof at 2000. This is serious power. The wind is cross-shore, so it’ll be a bit lumpy, but there’s a lot of water moving.

The real standout is Saturday the 29th. The morning brings a fresh offshore breeze and a solid 10ft west swell with a 13-second period. The combined energy is a massive 3090. This is the pick of the whole run. It’s going to be big, powerful, and clean, but this is expert territory only. Anything over 8ft is for the crew who know what they’re doing. The afternoon backs off a touch to 8ft and the wind stays offshore, making it a bit more manageable, but still heavy. The long period means it might be breaking a little straight at the beach, but the power will be there. Keep an eye on this one; it’s worth the wait.

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.
