Hong Kong records temperatures over 35°C before noon as Observatory warns of possible sudden rain and thunderstorms


30th May 2023 – (Hong Kong) Hong Kong is experiencing a prolonged heatwave due to the influence of sinking airflow from Typhoon Mawar, which is slowly moving towards the north-eastern coast of Taiwan. The Hong Kong Observatory has issued an “extreme heat warning” via its mobile app before noon today, with a predicted maximum temperature of 34 degrees Celsius. However, before noon, several areas in Hong Kong had already recorded temperatures over 35 degrees Celsius, with Yuen Long Park reaching 35.9 degrees Celsius. The Observatory also warned that the high temperature may cause sudden rain and thunderstorms in the coming days.

The sinking airflow from Typhoon Mawar is affecting the coastal areas of southern China, causing temperatures in most parts of Hong Kong to rise above 33 degrees Celsius at noon. Several areas have reported temperatures of over 35 degrees Celsius, with Yuen Long Park’s monitoring station recording a temperature of 35.9 degrees Celsius before noon.

The Observatory predicts that Hong Kong will experience “extreme heat” in the afternoon, with temperatures possibly reaching around 35 degrees Celsius, with light to moderate westerly to northwesterly winds. The extreme heat is expected to persist for the next two to three days, with a few rain showers and thunderstorms in some areas from Thursday. The rainy weather is expected to last until next Thursday.

As for Typhoon Mawar, it is currently located about 540 kilometres southeast of Kaohsiung, and it is predicted to move slowly towards the north-eastern coast of Taiwan. The Observatory advises the public to stay alert to the latest weather updates and take necessary precautions to stay safe and healthy during the heatwave.
