As of Thursday, the maximum temperature recorded at the Hong Kong Observatory reached 33 degrees Celsius (91 Fahrenheit) or above for nine consecutive days, marking the longest streak of very hot days for the month of August.
A green group warned in July that scorching days and hot nights in the months ahead would significantly increase the risk of heatstroke and other health problems linked to higher temperatures.
The heat has been felt particularly keenly by outdoor workers, prompting debate over whether the Labour Department’s heat stress warning signals are sufficient.
The signals are intended to alert outdoor manual workers, including construction workers and street cleaners, as well as those who work indoors with limited ventilation.
