The Hong Kong Observatory announced on Monday that last year it recorded an all-time high temperature on August 22 – 36.6 degrees Celsius – and the highest mean winter temperature since record-keeping began in 1884.

The city also experienced a record-breaking 41 hot nights, when temperatures remained above 28 degrees Celsius.

During the year, Hong Kong recorded only nine cold days where the minimum temperature dropped below 12 degrees – eight days less than the average number between 1981 and 2010. The lowest temperature recorded was 9.8 degrees on December 18.

“Globally, according to the World Meteorological Organisation’s preliminary assessment, 2017 is very likely to be one of the three warmest years on record,” wrote the Observatory.

“The weather in Hong Kong was warmer than usual in 2017 with an annual mean temperature of 23.9 degrees, 0.6 degrees above the 1981-2010 normal… and among the third warmest since records began.”

Hong Kong also experienced above-average rainfall and a very active typhoon season. The August 23 landing of Typhoon Hato – which caused the Observatory to raise the T10 hurricane signal – came a day after the city’s maximum temperature record was broken.
