I haven't been able to find any information specific to Fujian Province or Xiamen relative to any current drought effects in Xiamen.  So much of the information available on the internet is not current to August, 2022 or it deals with other provinces, mostly provinces along the Yangtze River and not with Fujian Province, home to Xiamen.

The Global Times reports: "Due to low rainfall and high temperatures, drought has occurred in six provinces -- Sichuan, Chongqing, Hubei, Hunan, Anhui and Jiangxi along the Yangtze River-- since July"

From another article:  "

• Numerous cities exceeded 111.2°F (44°C), China News reported. Temperatures this high are an acute public health threat."
