The Lowdown
Alright folks, Rusty here. Let’s get one thing straight right off the bat: the next couple of weeks are looking pretty grim for a paddle. We’ve got a lot of wind and messy conditions, but there are a couple of windows where it might just be worth the hassle.
The forecast kicks off with a long stretch of poor surf. From Friday the 28th through to the end of August, we’re looking at a mix of onshore and cross-shore winds that are just ruining what little swell there is. The water is sitting at 65°F around Larmor Plage, which is pretty much bang on average for this time of year, so at least you won’t freeze while you’re sitting there getting blown around.
The first real glimmer of hope comes on Tuesday, the 1st of September. Early morning, the wind swings to a light offshore from the north, and we’ve got a clean 4ft swell rolling in from the west. The wave energy is weak (256), so it’s not going to be a day of barrels, but it’s surfable. The wind is just a light breeze, so the surface will be clean. This is your best bet for a small, fun session. Larmor Plage is a beginner-friendly spot, but it’s inconsistent, so don’t expect it to be pumping all day.
Now, for the real standout. Mark your calendars for Saturday, the 5th of September. The morning is looking like the pick of the entire 16-day window. We’ve got clean conditions again, with a light offshore breeze from the north, and a 4ft, long-period groundswell from the west-northwest. The period is 12 seconds, which means there’s proper energy and shape in the water. The combined swell energy is moderate (355). This is a long-period swell, so it'll be a bit more lined up and powerful, but because Larmor Plage is a fairly exposed beach, it might break a little straight. Still, with the offshore wind, it’s going to be your best chance for a decent wave. The water is clean, and the wind is light.
Beyond that, it’s a wasteland. The second week is mostly tiny, weak, or windy. The 12th of September has a long-period, 17-second swell, but it’s only 2ft and the wind is howling from the west-southwest. That’s a kite-surfing setup, not a paddle session.
So, to sum it up: the first week is a battle against the wind, with Tuesday the 1st offering a small, clean window. The standout is hands down the morning of Saturday the 5th of September. Get on it, because after that, the forecast looks like a long, flat, windy lull.
Rusty.
