Hong Kong set to break hot nights record as ‘Great Heat’ day arrives Saturday
Hong Kong’s record of 13 consecutive hot nights is set to be renewed on Friday, coinciding with Saturday’s arrival of the “Great Heat” day in the traditional Chinese calendar when bright sunshine is forecast to send the mercury up to 37 degrees Celsius in some parts of the countryside.
The Hong Kong Observatory last recorded 13 “hot nights” - when the lowest temperature was 28 degrees or above - in a row in 2020, which is the most since records began in 1884.
The weather watchdog said a subtropical ridge is bringing generally fine weather to Southern China, with the maximum UV index today to be about 12 - meaning the intensity of UV radiation will be extreme.
The watchdog reminded citizens to take preventive measures against heat stroke and sunburn.
According to the Observatory, the coming nine days will remain hot, with temperatures at a high of 35 degrees till Monday, before dropping to 33 degrees on Friday.
The minimum temperature will hover around 28 degrees in the coming nine days.
The increase in temperature coincides with the arrival of the “Great Heat” day tomorrow. The day is the 12th of the 24 solar terms in the traditional Chinese calendar when sweltering heat has reached its peak.
The temperatures could hit a high of 37 degrees in Sheung Shui and Ta Kwu Ling in the northern New Territories on Saturday. Tai Po, Shek Kong in Yuen Long, and Chek Lap Kok on Lantau Island could also see a maximum temperature of 36 degrees on the same day.
During July 2020, there were a total of 20 “very hot days,” when the daily maximum temperature hit 33 degrees or above, compared with 17 days for the same month last year. This year has seen 12 days with maximum temperatures hitting 33°C or above so far in July.
