Biarritz - Cote des Basques Surf Forecast and Surf Report

Alright, so here’s the deal. The Bay of Biscay’s got some swell coming, but you gotta pick your moments. The first few days are a total write-off – Monday the 7th is small and messy, Tuesday the 8th is the same old onshore story, and Wednesday the 9th bumps up to about 6ft but it’s all chopped up by a stiff cross-onshore. Not worth the effort, honestly.

The real window opens up on Thursday the 10th of September, early morning. The wind goes dead calm – glassy as a lake – and there’s a nice 5ft NW swell running. The water’s sitting at 74°, which is a solid few degrees warmer than usual for this time of year. That’s a proper anomaly. That’s the session for a fish or a funboard. Clean, pushy, and uncrowded.

The weekend after that fades fast. Friday morning the 11th sees the swell drop to a tiny 2ft, and it just gets smaller and weaker through Sunday the 13th. Not much to report.

Then we get to the big one. Monday the 14th of September – that’s your standout. Early morning at Biarritz - Cote des Basques is glassy again, with a light offshore wind from the ENE. The swell is a solid 5ft from the NW, and the period is a long 12 seconds. That’s proper groundswell. The energy is moderate, right around 574. That’s the call. Clean, lined-up, and the water’s still warm. The afternoon gets chopped up, but that morning is money.

The 17th and 18th see a big pulse – 7ft to 8ft swell, energy spiking over 1000 – but the wind is either onshore or cross-onshore. That’s a lot of raw power, but the surface is going to be a mess. Maybe for the crew on guns, but not for a clean session.

Now, the 19th of September (Saturday) shapes up real nice. That morning, a stiff offshore easterly breeze at 20 km/h cleans up a 5ft NW swell perfectly. The break will have some real shape, and the crowd might be there since it’s a weekend, but the conditions are worth it. The afternoon stays clean with a cross-offshore flow.

The 20th (Sunday) morning also looks good – glassy, with a light wind and a solid 5ft NW swell. Good potential for a long, relaxed session.

The run continues into the 21st and 22nd with smaller swell, but the winds get tricky. The morning of Tuesday the 22nd has a nice cross-offshore breeze and a 4ft NW swell with a decent 11-second period – another clean option to round it out.

To sum it up: the standout is Monday the 14th of September, early morning. Glassy, groundswell, warm water. Your backup is Saturday the 19th of September for that clean offshore wind. The rest is a mix of chop and small stuff, but those two are the real deals.

Watch the tides at Biarritz - Cote des Basques – it’s a beach and reef setup that can get a bit shallow on the low.
