Just move back from the river… is what you’re probably shouting at the screen. Despite being a regular occurrence, the tidal bore that swept up the Qiantang River in China's Zhejiang province on Wednesday took onlookers by surprise, throwing a cloud of dirty water over the barriers, leaving many soaked and writhing on the ground. The unusual shape of the river sends these huge waves careering upstream, with the Qiantang bore believed to be the largest in the world, boasting waves more than 11 metres high.

The spectacular sight of Qiantang River Tide usually falls on the 18th day of the eighth month in the Chinese lunar calendar. This year, affected by the supermoon, the tide came with strong bores and even injured spectators after surging over the bank.
