The temperature was 28.3 degrees, 1.9 degrees, 1.4 degrees and 1.5 degrees higher than the normal value, which were the highest monthly averages since record.
The number of hot nights in July this year reached 21 days, the month with the highest number of hot nights on record. The 11 consecutive hot nights that began on July 5th also set the record for the longest consecutive hot night in July. In addition, the number of hot weather days in July was 20 days, the highest in a single month on record. As the weather continues to be fine, July is also much drier than normal. The total rainfall for the whole month is only 125.4 mm, which is about 33% of the normal value of 376.5 mm. The accumulated rainfall in the first seven months of this year was 1088.8 mm, which was about 26% less than the normal value of 1473.3 mm in the same period.
As the subtropical ridge of high pressure stretched westward from the Pacific Ocean to cover southeastern China, the weather in Hong Kong remained fine and very hot from July 11 to July 30, except for a few showers. During this period, the extremely hot weather triggered thunderstorms in some areas on the 17th, 21st, 22nd and 27th to 29th. Under sunny conditions and breeze, the temperature recorded at the Hong Kong Observatory on the 23rd rose to 35.3 degrees, the highest in the entire month.
