Hong Kong was like a big oven on Sunday, with temperatures in several districts rising above 37 degrees celsius, the Hong Kong Economic Journal reports.
Cheng Yuen-chung, senior scientific officer of the Hong Kong Observatory, said as high as 34.8 degrees celsius was recorded at its Tsim Sha Tsui headquarters in the afternoon.
It was the hottest day this year.
The highest temperature was in Chek Lap Kok at 37.7 degrees at one point, matching the previous record set there on Aug. 9, 2015.
Kowloon City and Sai Kung hit 37.3 and 37.2 degrees, surpassing their records of 36.9 and 37.1 degrees set in 2008 and 2015, respectively.
Cheng said the high temperatures were caused by the outer subsiding air of Typhoon Nesat and Tropical Storm Haitang, and the hot air mass was mainly from the northwest, where temperatures are generally higher.
The Observatory expected sea air from the west and the southwest to lower the temperature to 27 to 32 degrees on Monday, Cheng said.
At least seven people were reportedly stricken by heatstroke during the weekend, after a “very hot weather” warning issued by the Observatory.
A man, aged 19, who is said to be a student of the University of Hong Kong, was brought to North District Hospital on Sunday and remained in critical condition after suffering a heatstroke during a mountain hike.
The Centre for Health Protection called on people engaged in outdoor activities to take adequate precautions.
The Senior Citizen Home Safety Association said its personal emergency link service received more than 900 calls from the elderly on Sunday, including 53 people who needed to be hospitalized.
Air pollution was worsened by the heat wave, with Air Quality Health Index readings in the Central and Western District, Kwun Tong and Sha Tin all reaching 10, or “very high” health risk, while those in Tuen Mun and Tseung Kwan O posed “serious” risk.
Meanwhile, three buildings in Fu Tai Estate, a public housing estate in Tuen Mun, experienced a blackout at about 1 a.m. on Monday, news website hk01.com reports.
Technicians from CLP and the Housing Department said the surge of electricity usage might have caused overloaded power supply units to trip.
The electricity was back about three hours later.
