Hong Kong experienced its hottest month on record in July 2022, according to the Hong Kong Observatory (HKO). In a Facebook post on Monday, the city’s meteorological agency stated that 11 of the city’s weather records were broken or equalled last month.
According to the HKO, Hong Kong experienced 10 days with temperatures of 35 degrees Celsius or higher, which broke the annual record in a single month. The city also had the highest monthly mean temperature of 30.3 degrees Celsius, breaking the previous record set in 2020. The observatory issued 21 hot weather warnings in July, the most during a single month.
Other observations about July 2022 that the HKO made include:
- Highest monthly mean maximum temperature of 33.3 degrees Celsius, equalling the 2020 record
- Highest monthly mean minimum temperature of 28.4 degrees Celsius, breaking the 2020 record
- 16 days with 34 degrees Celsius or above, the highest in a single month
- 25 hot nights, the most in a single month
- The longest period of consecutive hot nights at 21 days
- The maximum temperature on July 24 was 36.1 degrees Celsius, the highest ever recorded in July
- The minimum temperature on July 25 was 29.9 degrees Celsius, the highest ever recorded in July
- The mean temperature on July 24 and 25 both reached 32.0 degrees Celsius, the highest on record for July
The HKO attributed this to a stronger than normal sub-tropical ridge that covered southern China during the month. However, the observatory forecast lower temperatures for the coming week, as “an upper-air disturbance is expected to bring heavy showers and thunderstorms to southern China in the middle and latter parts of this week.”
