The Lowdown
Right then… let’s see what we’ve got here in the Larmor Plage region. Honestly, mate, this stretch of coast is lookin’ pretty quiet for the next couple of weeks. Most of the time the swell’s weak and the wind is either cross or onshore, choppin’ things up. You’ll be huntin’ for a clean window and you won’t find many.
Thursday morning August 13th – we kick off with a 3 ft west swell at 10 seconds, but the wind is cross from the west at 6 mph. It’s just messy. Wave energy is moderate at best (220). Comes with that “poor surf conditions” tag. That’s a no-go for me.
The first half-decent chance shows up Friday morning August 14th. Larmor Plage gets a 3 ft west swell, 9-second period, but the wind is offshore from the north-northwest at 9 mph. It’s clean, gentle breeze. Wave energy is low (139). It won’t blow you away but it’s surfable – just ordinary. This break is rated for beginner, but it’s inconsistent. There’s some crowd potential here – you might see a few out, but nothing crazy. Water temp is about average for this time of year, no real anomaly.
Then, Saturday morning August 15th: similar deal, 3 ft from the west-northwest, 8 seconds, light offshore breeze from the north-northwest (6 mph). Clean again, but the wave energy’s weak (131). You’ll catch a few small slow ones.
After Saturday morning, a real flat spell hits. From Sunday August 16th right through Wednesday August 27th, it’s a long stretch of tiny, weak, or just poorly conditioned surf. Swells barely reach 3 ft, periods short (mostly 6–9 seconds), and the wind nearly always screws it up. There are a couple of moments with offshore or clean cross-off wind – like Thursday morning August 20th (3 ft, 9 seconds, 140 energy), or Friday morning August 21st (3 ft, 10 seconds, 192 energy) – but they still rate “poor surf conditions.” The waves just don’t have any push or shape.
Honestly, the best you get in this whole 16-day window is probably that Friday morning August 14th or Saturday morning August 15th. A small clean wave for a beginner to cruise around on. Nothing bigger than about 3 ft, so it’s fine for learning. The swell direction is from the west, which aligns with the optimum for this spot. But this is not a week for the experienced crew – there’s just not enough power. The combined energy never gets above 344 (that’s on Monday August 24th, but the wind is cross-onshore and it’s choppy – no good). If you’re a kiter, maybe some of those blustery afternoons with bigger winds and cross-shore conditions might get you interested. For a surfer? It’s slim pickings.
No real standout, no big groundswell to get excited about. A flat run like this – it’s pretty normal for this area. Keep an eye out, forecasts can flip.

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.
