In 2025, China faced one of its warmest and wettest years ever, according to the China Climate Bulletin released by the China Meteorological Administration (CMA). The report highlights significant shifts in weather patterns and the challenges they pose to various sectors.
The average temperature in China hit 10.9°C, a full degree above the average from 1991 to 2020. This tied 2025 with 2024 as the hottest year recorded since 1951. All seasons saw higher temperatures, with summer being the hottest on record. Notably, there was a significant rise in extremely hot days, along with intense heat events occurring more frequently than ever before.
Rainfall also showed dramatic shifts. The average annual precipitation reached 668 mm, about 4.5% above normal, marking 2025 as an exceptionally wet year. However, rainfall wasn’t evenly distributed. Northern regions experienced record-breaking rainfall and the longest rainy season ever, while southern areas saw less overall precipitation.
North China had the most rainfall in history.
Western China recorded its highest autumn rainfall ever.
There were many intense summer rain events.
Overall, the country had fewer days with rain, the third lowest on record.
Interestingly, despite the heavy rainfall, meteorological droughts were generally mild but varied by region and season.
The number of typhoons, both generated and making landfall, surpassed the long-term average. This led to localized flooding and damage to infrastructure. Although severe weather events were less frequent, their localized impacts were considerable. The frequency of gale days reached its highest level since 1991, raising concerns for transportation, agriculture, and energy sectors.
Experts argue that these trends highlight the growing impact of climate change on weather patterns. Increasing risks to water security, food production, urban resilience, and public health are evident. For instance, a recent survey indicated that 82% of urban residents feel unprepared for climate-related challenges. This underscores the urgent need for enhanced climate monitoring, early warning systems, and adaptive planning.
In summary, as weather extremes continue to rise, it’s essential for China to bolster resilience strategies across all sectors. Adequate preparation and proactive measures can help mitigate the effects of future climate events.
