Les Alcyons Avalanche

Les Alcyons Avalanche is a surf spot on the Basque Coast in France, in the Biarritz/Anglet area. It’s not one of the most famous headline beaches like La Côte des Basques or Grande Plage, but it’s a solid local reef/beach-break style spot that can light up when the swell and tide line up.

General character

• Wave type: Mostly a beach break with shifting banks in the general Anglet/Biarritz zone, though conditions can feel reefy in places depending on the sand and nearby structure.
• Best for: Intermediate to advanced surfers, especially when the swell is powerful and the line-up is well organized.
• Vibe: More local and less touristy than the main city beaches, with a typical Basque Coast mix of experienced surfers and strong local knowledge.

Conditions

• Swell: Works best with Atlantic NW to W swells, common in autumn and winter.
• Wind: Cleaner with east/northeast offshore winds; onshore westerlies can make it messy fast.
• Tide: Tide sensitivity is important on the Basque Coast—many spots here prefer mid tide or specific tide states depending on sand movement.
• Power: Can get strong and punchy, especially during bigger winter swell events.

What to expect

• Faster, more powerful waves than a mellow beginner beach.
• Can hold decent size when other spots are too small.
• Conditions can change quickly with sand movement after storms.
• Best sessions often come after a good swell cycle when banks have organized.

Hazards

• Strong currents and rips are common on the Basque coast.
• Can be crowded when conditions are good.
• Water can be heavy and the waves can close out if the bank is off.
• Winter surf may require a good wetsuit due to cool Atlantic water.
