On June 21, skateboarders across the globe headed outdoors to celebrate what is known as the official holiday of their sport: Go Skateboarding Day.

Go Skateboarding Day was founded in Southern California, the sport’s unofficial capital, in 2003. It was dubbed as an excuse for skateboarders to make skateboarding their top priority. More specifically, according to the Go Skateboarding website, Go Skateboarding Day is a day “to define skateboarding as the rebellious, creative celebration of independence it continues to be.”

Founded by the International Association of Skateboard Companies (IASC), the day gives both skateboarders and skateboarding fans the opportunity to drop everything, gather with fellow boarders and either hop on a skateboard and start shredding or stand on the sidelines to cheer on demonstrations of exhilarating speed and perfectly executed tricks.

Temperatures in New York City were above 90 degrees, but that didn’t stop urban boarders from taking part. Check out the photos below for a glimpse of the action.
