The minimum pressure recorded at the Hong Kong Observatory was 1003.0 hectopascals at 1647 HKT on 16 May.
The maximum air temperature recorded at the Hong Kong Observatory was 32.4 degrees C at 1507 HKT on 31 May.
The minimum air temperature recorded at the Hong Kong Observatory was 20.6 degrees C at 2103 HKT on 3 May.
The maximum gust peak speed recorded at Waglan Island was 65 kilometres per hour from 070 degrees at 1950 HKT on 20 May.
The maximum instantaneous rate of rainfall recorded at King's Park was 138 millimetres per hour at 0553 HKT on 2 May.
^ In case the data are not available from Waglan Island, observations of Cheung Chau or other nearby weather stations will be incorporated in computing the Prevailing Wind Direction and Mean Wind Speed.
* Wind data recorded at Cheung Chau were used for 12 May to 16 May due to malfunction of A/C supply at Waglan Island.
