The minimum pressure recorded at the Hong Kong Observatory was 1008.5 hectopascals at 1524 HKT on 25 November.
The maximum air temperature recorded at the Hong Kong Observatory was 28.6 degrees C at 1342 HKT on 13 November and at 1248 HKT on 15 November.
The minimum air temperature recorded at the Hong Kong Observatory was 15.8 degrees C at 0127 HKT on 18 November.
The maximum gust peak speed recorded at Waglan Island was 81 kilometres per hour from 010 degrees at 2140 HKT on 16 November.
The maximum instantaneous rate of rainfall recorded at King's Park was 55 millimetres per hour at 1847 HKT on 16 November.
^ 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 from Cheung Chau were used for 19-24 November due to malfunction of the anemometer at Waglan Island.
