The day's competition has been rescheduled to July 29.

A media centre representative said the skaters were unable to compete because the surface of the street course was too slick due to persistent rain early on Saturday, making conditions unsafe.

La Concorde, a sprawling outdoor venue where thousands are expected to for the breaking, skateboarding, BMX freestyle and 3x3 basketball events, sat quiet on Saturday with empty stands.

Workers walked through the waterlogged grounds and the street skate course sat slick was water as rain pooled into empty seats.

It was a far cry from the lively "urban park" environment organisers had hoped to unveil the morning after a soaking-wet opening ceremony in which athletes and fans were drenched by rain.
