The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the coming weeks.
Honestly, for the first ten days or so, it's a bit of a flat spell. The swell is tiny, the period is short, and we've got a lot of onshore wind. Mostly, it's not worth paddling out for. We're looking at a long stretch of nothing much from now until the 27th of August. There's a tiny bit of energy on the 20th, but it's all onshore junk. The 22nd shows some clean conditions with a NE breeze, but the swell is only 2ft and weak. The 23rd has a clean offshore from the ENE, but again, the swell is a paltry 1.0ft. It's a frustrating wait.
The first real sign of life comes on the morning of Thursday, the 27th of August. The swell finally bumps up to 4ft from the WSW, with a period of 8 seconds. The combined energy is moderate (197), and we get a clean, cross-offshore wind from the North. Rade de Croisic will be the spot to check. It's not a massive day, but it's the first surfable wave in over a week. The water temp is about average for the time of year at 69°.
Now, the standout is shaping up for the morning of Sunday, the 30th of August. This is the one to circle on the calendar. We're looking at a 6ft swell from the WSW, and the wind is forecast to be glassy – dead calm. That means the surf will be clean and smooth. The combined energy is moderate (398), and the period is 8 seconds. It's a great window for a session. The afternoon gets messy with onshore wind, so make it a dawn patrol.
The day before, Saturday the 29th, has a bigger swell coming in—7ft from the WSW with a very long 12-second period. The combined energy is strong (1268), but the wind is a fresh cross-onshore, which will make it lumpy and choppy. For a more exposed beach break, that combo might be more interesting for the kite surfers than paddle boarders. The 28th also sees a pulse of 7ft, but again, the wind is cross-on, making it a bit of a mess.
To wrap it up, the first week and a half is a write-off. The 27th offers the first chance for a surf, but the real winner is the glassy morning of the 30th of August. Long-range, the 31st morning has a 5ft swell with a decent 10-second period, but with cross-on wind, it's marginal.
