The minimum pressure recorded at the Hong Kong Observatory was 999.6 hectopascals at 1620 HKT on 19 June.
The maximum air temperature recorded at the Hong Kong Observatory was 34.2 degrees C at 1602 HKT on 20 June.
The minimum air temperature recorded at the Hong Kong Observatory was 22.4 degrees C at 1919 HKT on 11 June.
The maximum gust peak speed recorded at Waglan Island was 78 kilometres per hour from 080 degrees at 1700 HKT on 14 June.
The maximum instantaneous rate of rainfall recorded at the Hong Kong Observatory was 210 millimetres per hour at 0521 HKT on 22 June.
# 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.
