Based on the fixed-point observation data in Qianhai Bay of Shenzhen in May 2020, the horizontal and vertical distribution characteristics of tidal current, wave in summer near Qianhai Bay of Shenzhen are analyzed. The results show that the correlation coefficient of high and low tide level between the Qianhai Bay and Chiwan hydrological station is 0.98. The former Bay is dominated by irregular semidiurnal tidal current, which basically rotates anticlockwise. Due to the special shape of Qianwan Bay, the average velocity in the bay is small, but the maximum velocity of flood tide is 0.48m/s, the maximum velocity of ebb tide is 0.45m/s, the possible maximum velocity is 0.64m/s at the bay mouth. The average wave height is 0.07m, the normal wave direction is southwest West (WSW), and the average period is 2.9s.
