Hot, hazy day for Hong Kong as air quality poses ‘very high’ health risk in Central, Causeway Bay and Mong Kok 

Weather to remain sunny with low visibility through the day, with one or two isolated showers in the afternoon

A blanket of heavy pollution smothered Hong Kong’s biggest business and shopping districts on Wednesday.

Citizens braving the sweltering heat also had to put up with pollution levels categorised as “very high” in Central, Causeway Bay and Mong Kok.

According to the Environmental Protection Department, as of 11am the air quality health index had reached 8 at roadside stations in the two districts, indicating a very high health risk. Roadside stations in Mong Kok and general stations in Tuen Man and Tai Po reported AQHI readings of 7, indicating a high health risk.

In Central, the level of harmful PM2.5 particulates had reached 107 micrograms per cubic metre, four times the World Health Organisation’s safety limit of 25 and well above Hong Kong’s limit of 75. In Causeway Bay, the level reached 101.

The Environmental Protection Department advises children, the elderly and those with existing heart or respiratory illnesses to reduce outdoor activities to a minimum when the health risk is very high.

“The general public are advised to reduce, or reduce to a minimum, outdoor physical exertion, and to reduce time outdoors, especially in areas with heavy traffic,” a spokesman for the department said.

According to the Hong Kong Observatory, the pollution was brought by high pressure over the western North Pacific as well as light winds locally.

“The visibility fell to about 3,000 metres over many places,” the Observatory said in its weather report.

According to the report, it will remain hot and sunny with low visibility through the day, with one or two isolated showers in the afternoon.

It will be mainly fine and hot over the next couple of days.

As of 10am, the Observatory recorded 28 degrees Celsius in Tsim Sha Tsui. Temperatures reached 30 degrees in Sha Tin, Tseung Kwan O, Tsing Yi, Tsuen Wan Shing Mun Valley, Kowloon City, Happy Valley, Wong Tai Sin, Kwun Tong and Sham Shui Po.
