Les Dunes Surf Forecast and Surf Report

G’day, Rusty here. Let’s be straight—this stretch is a mixed bag, and for a while, it’s about picking the right session, not chasing any big swell. The water’s at 69.6°F at the first break we’ll talk about, which is a touch warmer than normal for this time of year, so that’s a small win.

The first real call is for Saturday morning, the 12th of September. It’s small, only 2.3ft of west swell at Les Dunes (Le Touquet-Paris-Plage), with a short 8-second period. The energy is weak (64), and while it’s glassy with a light SE breeze, it’s just not got much push. It’s surfable, but you’ll be working for it. The afternoon turns cross-on and choppy, so that morning window is the only one.

Sunday the 13th is a touch better. The swell bumps to 2.6ft, and the period stretches to 10 seconds, giving it a bit more shape. Morning glass again, and the energy is moderate (127). It’s still not epic, but it’s cleaner and has more life. The afternoon gets ruined by a cross-shore, so again, get on it early.

Monday morning the 14th is your first real clean window. 2.3ft of W’ly swell with a 10-second period, a light cross-off breeze, and moderate energy (102). It’s clean and lined up. But it’s all pretty ordinary until a notable pulse arrives.

Now, look at Wednesday the 16th. The swell jumps to 4.3ft, but the period is only 8 seconds, and the energy is moderate (233). The problem is it’s predicted to be too big for this break, and with a cross-off wind, the morning might have some juice, but it could be messy. Thursday the 17th sees a similar situation—3.6ft, but the period stretches to 11 seconds and the energy climbs to 292. Again, it’s too big for the break, and there’s a cross-shore. This is expert territory.

But then, hold on. Friday the 18th morning looks like the pick of the first week. The swell drops back to a clean 2.3ft, west-northwest direction, with a 9-second period. The energy is moderate (201), and you’ve got a light cross-off breeze, making it clean. It’s the best balance of size and shape. Then Saturday the 19th morning is a standout. 2.6ft of WNW swell, a 12-second period, light offshore NE wind, and the energy is solid at 202. That’s clean, lined-up surf with a proper groundswell pulse. This is the one to circle.

We roll into the second week, and the quality fades as the swell drops. Monday the 21st morning has a fun pulse—2.6ft west swell at 15 seconds, with a moderate offshore wind and energy at 353. That’s a long-period, clean morning, and it’s worth getting out for. But the afternoon gets questionable. From Tuesday the 22nd onwards, things get small—down to 2ft and less, and the period drops. The energy fades to weak (44-115), and while there are clean moments, they’re not really worth the paddle. The longer period on Thursday the 24th (14 seconds) is there, but the swell is tiny at 1.3ft.

The last real notable is Sunday the 27th, but it’s a mess. 3.6ft of short-period NW swell at 5 seconds, with onshore winds. The energy is weak (93), and it’s just lumpy, cross-on junk. This stretch is not for the board.

So, in the short term, don’t hold out for quality. Get out on Saturday the 12th morning if you’re desperate, but the true standout is Saturday the 19th morning—that long-period groundswell with clean offshore conditions is your best bet. The Monday the 21st morning is a promising second option, but you’re looking at ankle to waist-high waves at best. The second week is mostly flat and poor, so save your energy.

The beach setup at Les Dunes is exposed, so when the swell is over 3.3ft and the wind is cross, it’s going to be a wash. On those days, it looks more interesting for the kites than the paddleboards.

Keep it salty.
