[1]:Only showing cases since 1967 with maximum tide height over 3.8m. Tide heights are measured with respect to Macau Chart Datum.

[2]:Maximum flood heights before 2009 are estimated from the difference between maximum tide height and Inner Harbour pavement level (Inner Harbour pavement level is 3.2m above Macau Chart Datum). Maximum flood heights from 2009 onwards are based on real-time data from water level monitoring stations.

[3]:Maximum flood height is obtained by estimation due to power outage of monitoring stations during storm surge.
