August sees hot, stormy weather

September 04, 2017

August was hotter than usual with a mean temperature of 29.3 degrees Celsius, the seventh-highest on record for the month and 0.7 degrees above normal, the Hong Kong Observatory says.


Hong Kong was struck by two tropical cyclones within five days during the month, which saw the hoisting of Hurricane Signal No.10 on August 23 for the first time since 2012.


Due to the storms, the monthly total rainfall amounted to 489.1mm, 13% above normal.


There has been 2,248.9mm of rainfall so far this year, 18% above normal.


The approach of Typhoon Hato coincided with an astronomical high tide, causing a storm surge and bringing unusually high water levels and serious flooding to many parts of Hong Kong, including Tai O, Heng Fa Chuen, Lei Yue Mun, Sha Tin and Lau Fau Shan.


The water level at Quarry Bay rose to 3.57m, the second highest on record after Super Typhoon Wanda in 1962 which saw a high of 3.96m.
