The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for the next couple of weeks.
To be straight with you, the Rade de Croisic is looking like a tough stretch. We’ve got a solid run of poor surf conditions with choppy, lumpy, and messy waves driven by cross-onshore winds. The wave energy is weak to moderate at best, with combined energy values mostly in the low hundreds or even below 100, and the water temperature is about average for this time of year. The only real standouts are a couple of cleaner windows later in the period, but even then, the swell is small and ordinary.
Monday the 7th is a washout – WSW wind at 9 mph to 12 mph, cross-on and onshore, with 2.6 ft to 3.6 ft of WSW swell at 13 to 15 seconds. The energy is moderate (301 to 437), but the conditions are just poor. Tuesday the 8th doesn’t get any better – strong wind at 28 mph in the morning, messy and lumpy, with 4.3 ft to 4.9 ft of WSW swell dropping to short-period 7 seconds in the afternoon. That’s too big for beginners and only for experts if you’re desperate, but with the wind, it’s not worth it.
Wednesday the 9th stays poor with moderate cross-onshore breeze and 3.6 ft of W swell at 9 seconds. The energy is moderate (312 to 314), but the chop is real. Thursday the 10th is tiny – 1.6 ft of W swell, glassy in the morning, but the energy is barely a whisper (38). The swell is too small for a proper ride. Friday the 11th has a bit more juice (2.6 ft to 3.3 ft, W swell, 9 to 10 seconds, energy 186 to 256), but onshore wind keeps it messy.
Saturday the 12th is glassy in the morning with 1.6 ft of W swell at 8 seconds, but again, tiny. Sunday the 13th sees a long-period W swell at 16 seconds and 1.6 ft, energy 167, but it’s onshore in the afternoon. That long period would be better for a point or reef, but here at the beach, it’s likely to break too straight.
The first real glimmer comes on Wednesday the 16th. Morning shows a clean, cross-offshore wind from the NNE at 9 mph, with 3.6 ft of W swell at 11 seconds. The energy is solid (448) and the conditions are clean. It’s only a marginal forecast, but this is the best of the first two weeks. Thursday the 17th is similar – clean cross-offshore in the morning (ENE, 9 mph), with 4.3 ft of W swell at 10 seconds, energy 347. The afternoon picks up to 4.9 ft with energy 757 (moderate to strong), but with onshore wind, it’s less appealing.
The best offering in the whole outlook is Friday the 18th. Morning sees a true offshore wind from the E at 9 mph, clean, with 2.3 ft of W swell at 9 seconds. The energy is low (103), but the wind is offshore and the conditions are surfable. It’s not a big swell, but for a clean, small wave session, it’s your pick. The afternoon goes onshore, so get in early.
There’s a gap from Saturday the 19th through Sunday the 20th with nothing but poor surf. Monday the 21st offers another chance – moderate offshore wind from the ENE at 12 mph, 3.0 ft of W swell at 8 seconds, energy 105. It’s ordinary but clean. Tuesday the 22nd wraps it up with a similar story: ENE wind at 16 mph, offshore, 2.3 ft of W swell at 7 seconds, energy 54. Small but clean.
So, the takeaway: the first eleven days are mostly a write-off. The standout is Friday the 18th morning for clean, offshore waves, even if they’re small. Wednesday the 16th and Thursday the 17th mornings are worth a look for cleaner conditions with a bit more size. The rest is for the kites or the coffee shop.
