Qiantang Tidal Bore

The Quiantang tidal bore has the Guiness world Record for the worlds largest tidal bore. It has been known to reach up 8.9m in hight and speeds up to 4km/h. Tidal Bores are becoming more popular among the surfing community as they are very large and can go up rivers up to 10km. Tidal bores are made by the tide when the moon is in the best position. It is celebrated locally during the Tidal Bore watching festival on the 18th day of the Chinese Lunar Calender.
