International Coastal Cleanup Day is observed annually—an initiative aimed at raising awareness about pollution in coastal ecosystems and encouraging active participation from communities, businesses, and visitors in their conservation. In Mexico, the event is celebrated on the third Saturday of September; in 2026, this falls on September 19.
The observance was established by The Ocean Conservancy in 1991 as part of the Global Cleanup campaign’s international programs. Its purpose is to mobilize thousands of people to remove waste from beaches, rivers, and wetlands, while also identifying major sources of pollution and fostering changes in habits that generate trash.
