The Lowdown
Alright, Rusty here. Let’s cut through the noise and get straight to what matters for Larmor Plage.
First up, I gotta be straight with you: the next week-plus is looking pretty grim. We’ve got a long stretch of poor surf conditions, with onshore or cross-shore winds ruining just about everything. From Thursday the 27th of August right through to early September, you’re looking at small, weak waves and choppy, lumpy conditions. Nothing worth paddling out for. That’s a solid week of frustrating, flat-to-messy surf. The wind just won’t give us a break.
Then, things start to shift. The first real glimmer of hope comes on Monday the 31st of August. The swell ticks up to 7 ft from the west with a period of 10 seconds, and the combined energy hits a moderate 847. It’s still cross-shore wind, and the forecast calls it “marginal,” but it’s the first sign of life after a long flat spell. Not a stand-out, but a window.
The true highlight is tucked away later. On Sunday the 6th of September, conditions finally line up. It’s a morning session for the experienced crew. The water temp is 64°, which is normal for the time of year – no anomalies to worry about here. The swell bumps up to 8 ft out of the WNW with a 10-second period, and the combined energy is a powerful 1785. That’s ramping up. The kicker? The wind is dead calm, glassy. Clean conditions. That’s the kind of morning that gets the heart pumping. The break itself is a fairly exposed spot, so it’ll catch this energy well. The swell size is over 8 ft, so this is expert territory – keep the beginners on the beach. This is your only true standout of the whole 16-day outlook. The long period (12 seconds) a couple days earlier points to clean groundswell energy, but the wind wasn’t right then.
Before that, on Saturday the 5th of September, there’s a small pulse with a very long 12-second period and 3 ft swell, but it only scores as marginal. The wind is light but cross-shore, so it’s a slim chance for a quiet, clean-ish wave if you’re desperate. The 8th of September has some cleaner offshores, but the swell is only 4 ft and consistency is questionable.
So, the verdict: This forecast is mostly a test of patience. The highlight is the glassy, powerful morning of the 6th of September at Larmor Plage. That’s your date.
Rusty.
