Cities across Guangdong are facing extreme heat, with the provincial weather bureau forecasting a maximum temperature of 35 to 37°C in areas such as the Pearl River Delta, eastern Guangdong and Zhanjiang between today and tomorrow. 

Within the Greater Bay Area (GBA), Guangzhou is expected to be hit with scorching temperatures ranging up to 36°C over the next several days, alongside occasional showers and thunderstorms. 

Yesterday, multiple districts in the provincial capital, including Liwan, Baiyun and Haizhu, issued their first orange high temperature alert of 2026 after the mercury hit 37°C. 

Shenzhen is also baking, with local meteorologists reporting temperatures of up to 34°C  in certain areas, along with brief thunderstorms today and tomorrow. Meanwhile, the north-central part of the tech hub, as well as districts with a high population density, are forecast to record a mercury of 37°C or above over this period.  

In light of the blistering heat, Shenzhen has sent out a yellow hot weather alert. 

The SARs of Hong Kong and Macao have not been immune to the scorching weather either. According to the Hong Kong Observatory, the city’s temperature is forecasted to reach a high of 34°C today.

“The weather tomorrow will be even hotter tomorrow, reaching extremely hot levels,” Lee Chi Hing, a meteorologist with the Hong Kong Observatory, said in a TVB report. “The New Territories will see even higher temperatures of 36°C to 37°C.”

Lee added that there would be some showers and thunderstorms on Saturday. The observatory has currently issued a “very hot” weather warning. 

Extreme heat is also impacting Macao, where temperatures in various districts are generally expected to hit a high of 34°C or higher today and tomorrow. In a dispatch yesterday, the Macao Meteorological and Geophysical Bureau said the maximum mercury in urban districts could be even higher by 2°C to 3°C. 

With a yellow hot weather alert currently in place, the forecaster advised the public to take precautionary measures such as staying hydrated and being cautious against heatstroke. 

Starting from Sunday, the bureau is anticipating several continuous days of increased showers and thunderstorms due to the onset of a southwest monsoon and a low pressure trough that will impact the coast of the South China Sea early next week.
