The Lowdown
Alright, Rusty here. Let’s be straight with you about Larmor Plage. I’ve looked over the coming weeks, and honestly, it’s a tough stretch. There isn't a single standout day that gets me buzzing. The pattern we’ve got is mostly small, weak swell with wind problems keeping things messy. There’s a real dry spell in the middle with very little to offer.
We start off on Saturday, the 15th of August, with the best chance you’ll see in this whole period but even that’s a struggle. The morning has a clean little 3ft swell coming out of the WNW with a short period of 8 seconds, and a light offshore wind from the NNW making for clean faces. The water here is sitting at 68°F with an anomaly of 2°F, so it’s just a touch warmer than average for the time of year. The combined energy is weak at (90). It’s surfable, but very ordinary. The afternoon on Saturday turns ugly with a cross-onshore wind and choppy conditions.
From the 16th of August right through to the end of the month, the story is pretty bleak. There are long gaps with nothing worth paddling out for. The swell stays below 3ft for most days and the wind never really cooperates to give us clean, lined-up waves. Mornings might look clean on paper, but the swell is tiny—under 2ft—with periods that are way too short to hold any shape. Even when we get a pulse of stronger energy, like on Thursday the 20th of August with a 4ft swell and combined energy of (286), the wind is a fresh cross-shore at 19 mph, ruining the surface.
Later in the second week, we see some offshore winds and glassy conditions, like on Friday the 28th of August morning, but the swell is barely 1ft. You’d be bobbing around on a lake. The same goes for the final weekend. It’s just not on. For a spot that’s only inconsistent at the best of times, this run of poor conditions is more normal for the area.
Look, it’s a blank run. There are no good surf options in this 16-day window for Larmor Plage. With the swell being this small and the wind working against us, I’d keep the board in the van and wait for the next system.
Rusty.
