Anglet - Les Dunes Surf Forecast and Surf Report

Alright, Rusty here. Let’s break it down.

First off, the water is about 73°F, which is 4°F warmer than usual for this time of year. That’s a notable bump in temperature, so you won’t need the thick rubber.

The first real surf worth talking about shows up on Sunday, September 13th, in the morning. Les Dunes gets a 4ft groundswell out of the NW, with a long period of 13 seconds. The wind is glassy, dead calm, so expect clean, lined-up waves. The combined energy is decent at moderate (545). This is a solid option for a beginner, and since it’s fairly consistent, you won’t be waiting forever. Keep in mind, crowds are possible here, but with that glassy morning, it’s worth the paddle.

Monday the 14th keeps the momentum. Another morning glass-off with a 4ft NW groundswell (11-second period) and moderate energy (453). Clean waves again, but the period is a touch shorter, so the shape might not be as fat as Sunday. Still, for a beginner-friendly spot, you’ll be stoked.

Now, things get dicey through the middle of the week. There’s a solid drop-off from Monday afternoon right through to Wednesday the 16th. The wind shifts cross-onshore or onshore, the period drops, and the quality goes poor. It’s a dry spell. Take a few days off.

Thursday, September 17th, morning is where it picks back up. A glassy start again, with a solid 6ft NW groundswell, 11-second period, and strong wave energy (703). This is getting bigger, but still manageable if you’re comfortable. The wind is dead calm—absolute glass. This is a standout for the first week. Expect those long-period sets to roll in nice and clean.

Then we hit the real headline act: Saturday, September 19th, morning. This is the best on offer. A 7ft NW groundswell with a very long period of 13 seconds. The combined energy is strong (1395). The wind is completely calm – glassy perfection. This is expert territory—over 7ft and with that long period, it’ll have some serious grunt and will be best for experienced surfers. It will be clean and powerful. This is the session to circle.

Monday, September 22nd, morning is another beauty. A 8ft NW groundswell (13 seconds) with offshore east wind at about 6 mph. The combined energy is very strong (1862). That’s a clean, powerful, expert-only wave. If you’ve got the skills, this is a bomb.

The following days (23rd to 27th) taper off. The swell drops, the wind turns onshore or cross-onshore, and it’s mostly poor. There's a brief window on Thursday, September 24th, morning with a 4ft NW groundswell and glassy conditions, but the energy is weak (226). It’s a marginal option at best.

So, to sum up: the standout windows are Sunday 13th morning, Thursday 17th morning for the clean glass, and the absolute top pick is Saturday 19th morning and Monday 22nd morning for experienced surfers chasing power and size.
