The minimum pressure recorded at the Hong Kong Observatory was 1011.8 hectopascals at 1518 HKT on 16 November.

The maximum air temperature recorded at the Hong Kong Observatory was 30.3 degrees C at 1212 HKT on 9 November.

The minimum air temperature recorded at the Hong Kong Observatory was 15.3 degrees C at 0652 HKT on 27 November.

The maximum gust peak speed recorded at Waglan Island was 62 kilometres per hour from 080 degrees at 0811 HKT on 10 November.

The maximum instantaneous rate of rainfall recorded at King's Park was 177 millimetres per hour at 1128 HKT on 15 November.

# Reduced visibility refers to visibility below 8 kilometres when there is no fog, mist or precipitation.

   - The visibility readings at the Hong Kong International Airport are based on hourly observations by professional meteorological observers in 2004 and before, and average readings over the 10-minute period before the clock hour of the visibility meter near the middle of the south runway from 2005 onwards. The change of the data source in 2005 is an improvement of the visibility assessment using instrumented observations following the international trend.

   - Before 10 October 2007, the number of hours of reduced visibility at the Hong Kong International Airport in 2005 and thereafter displayed in this web page was based on hourly visibility observations by professional meteorological observers. Since 10 October 2007, the data have been revised using the average visibility readings over the 10-minute period before the clock hour, as recorded by the visibility meter near the middle of the south runway.

^ 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.
