BEIJING, August 6, 2025 – A devastating monsoon surge has battered southern China, unleashing some of the worst rainfall in over a century, paralyzing major cities, flooding infrastructure, displacing thousands, and fuelling a dangerous outbreak of disease. The destruction is centered in Guangdong province, home to over 126 million people and some of China’s most important economic zones.
Second-Heaviest August Rainfall This Century Hits Guangzhou
Guangzhou, the capital of Guangdong and a global commercial hub, experienced its second-heaviest August rainfall since 1900, with torrential downpours causing widespread chaos. Baiyun International Airport, one of the world’s busiest, was forced to cancel 363 flights and delay another 311, as water submerged runways and access roads.
A day earlier, Hong Kong and the surrounding Pearl River Delta were pummeled with record-breaking rain — the most in August since 1884. Skies turned a foreboding shade of gray as sheets of rain poured for hours, overwhelming drainage systems.
Landslides and Floods Rip Through Communities
Emergency crews have been deployed across the province to clear debris, drain flooded streets, and reopen highways, which have been destroyed by mudslides and fallen trees. In north Guangzhou, a landslide struck “Taobao Village”, a community known for e-commerce businesses on Alibaba’s platform, trapping 14 people — 7 remain missing as of Wednesday.
Across Guangdong, 16 rivers are nearing dangerous levels, with water at two major monitoring sites reaching peaks not seen since 2017 and 2018. Officials are on high alert, fearing more breaches if the rains continue.
Disease Crisis Emerges Amid Standing Water
In the aftermath of the floods, a public health emergency is rapidly unfolding. The standing floodwaters have created a breeding ground for mosquitoes, triggering a resurgence of the chikungunya virus, a mosquito-borne illness that causes high fever and severe joint pain.
Authorities report over 7,000 cases so far in Guangdong, with the city of Foshan being the epicenter. More than a dozen cities across the province have reported outbreaks. Experts fear the worst is yet to come, as increased mosquito activity, fueled by typhoon rains, threatens to overwhelm disease prevention systems.
Though chikungunya is rarely fatal, its symptoms are debilitating, and the current resurgence could place additional strain on healthcare infrastructure already impacted by flooding. Video footage showed flooded emergency rooms in Hong Kong and other cities, struggling to operate amid rising water levels.
Economic Toll and Nationwide Impact
The Chinese government has allocated over 1 billion yuan ($139 million) in emergency relief to affected regions, including Guangdong, Beijing, Hebei, and Inner Mongolia. However, experts warn that the economic impact could be uneven and long-lasting.
Fruit and vegetable prices are expected to spike, and consumer-facing businesses such as shops and restaurants are seeing a steep decline in foot traffic. Industrial operations are also affected, especially those relying on logistics and exports through southern ports.
Cold chain logistics providers may see temporary gains as demand for refrigeration increases, but the broader economic picture remains bleak. With two to three typhoons forecast to strike China later in August, authorities fear worsening floods and further disruptions.
A Crisis Far From Over
Climate experts have tied this weather chaos to shifting monsoon patterns caused by climate change, calling this one of the most severe atmospheric events in China in recent decades. The prolonged and heavy rains have already displaced thousands of residents, while the threat of more landslides and disease looms large.
“This is not just a natural disaster — it’s a public health crisis, an economic shock, and a wake-up call,” said Dan Wang, a China expert at Eurasia Group.
With rising river levels, missing persons, and an escalating disease outbreak, southern China faces a multi-faceted emergency that will take weeks — if not months — to fully recover from.
