WATER QUALITY · SAFETY

Know before you
paddle out.

River plumes, osteopsis blooms, post-storm pollution. The ocean isn't always safe even when the surf is good. Olatu surfaces official water quality alerts from French health authorities directly on the spot card and forecast view, so you never have to cross-check a second app.

🌊

River plume

Bacterial contamination after heavy rainfall upstream

🔬

Osteopsis bloom

Toxic microalgae that can cause skin and respiratory irritation

⚡

Pollution event

Discharge or spillage flagged by the local authority
