The very hot weather in Hong Kong is expected to persist until midweek, with temperatures in some areas expected to reach 37 degrees Celsius or above, the Hong Kong Observatory said Sunday.

The HKO said in a weather advisory that Tropical Cyclone Dolphin’s outer subsiding air will persistently bring extremely hot weather to the territory on Sunday and Monday as it moves towards the vicinity of Zhejiang.

“High temperature weather is expected to continue midweek this week,” the observatory said.

The observatory added that it will be extremely hot in Hong Kong during the day on Sunday, with the mercury expected to range between 29 C and 36 C.

The Centre for Health Protection of the Department of Health reminded members of the public on Sunday to take appropriate precautions against heat-related illnesses, such as heat cramps, heat exhaustion and heat stroke after the observatory issued the very hot weather warning.

“Wear light-colored, loose-fitting and breathable clothing to minimize heat absorption and facilitate perspiration and heat dissipation,” the CHP said in a statement.
