Guangzhou Breaks Heat Record: Summer Persists into November
Guangzhou, a major city in southern China, is still experiencing summer weather in mid-November. The city has recorded 235 summer days this year, breaking a 30-year record. The previous record was set in 1994 with 234 days.
In Guangzhou, the switch from summer to autumn depends on temperature rather than a specific date. Autumn begins when the five-day average temperature drops below 22°C. This year, summer started on March 23. Current temperatures remain around 24.9°C, which is 1.2°C above historical averages.
According to Ai Hui, a senior engineer at the Guangzhou Climate and Agricultural Meteorological Centre, the city’s long summer is due to unusually weak pressure from the Siberian high. This has reduced cold winds reaching the area.
Guangzhou faced severe weather this year, including a tornado in April that killed five people and caused injuries. The region has also experienced significant flooding. Extreme weather events like droughts and heatwaves are increasingly common in China, straining infrastructure, especially electricity grids.
How can cities like Guangzhou improve their energy infrastructure in response to climate change?

In an exclusive interview, we spoke with Ai Hui, a senior engineer at the Guangzhou Climate and Agricultural Meteorological Centre, regarding the city’s unprecedented summer weather in mid-November and its implications for climate patterns in China.
News Directory 3: Thank you for joining us, Ai Hui. Guangzhou has experienced a record 235 summer days this year. What do you attribute this extended summer season to?
Ai Hui: The prolonged summer is primarily due to unusually weak pressure from the Siberian high. This atmospheric condition significantly reduced the influx of cold winds into our region, which has delayed our transition to autumn. Normally, we would see a drop in temperature, but this year the average temperature has remained around 24.9°C, which is about 1.2°C above our historical averages.
News Directory 3: You mentioned that autumn in Guangzhou is determined by temperature, specifically when the five-day average drops below 22°C. Could you elaborate on this method of classification?
Ai Hui: Yes, unlike many regions that simply rely on traditional dates for seasonal changes, we utilize temperature thresholds here in Guangzhou. This approach is more responsive to the actual weather conditions we experience. Unfortunately, with our current temperatures, we have yet to see that necessary drop, and it reflects wider climatic trends we’ve been observing.
News Directory 3: This year has also seen severe weather events, including a tornado and flooding. How do these fit into the larger picture of climate change in China?
Ai Hui: The increase in extreme weather events such as tornadoes, flooding, droughts, and heatwaves is consistent with the patterns driven by human-caused climate change. Comprehensive research indicates that many of the extreme weather incidents we’ve experienced over the past decade are not likely to have occurred without the influence of global warming. The implications for our infrastructure are significant, particularly for our electricity grids which are stretched to their limits during heatwaves.
News Directory 3: How did last year’s heatwave impact energy consumption in China?
Ai Hui: The 2022 heatwave was particularly drastic, resulting in record levels of electricity use as people turned to air conditioning to cope with the oppressive heat. This heavy reliance led to major power outages in many areas. It highlighted not only the vulnerabilities in our energy infrastructure but also the urgent need for comprehensive energy security strategies moving forward.
News Directory 3: Speaking of energy strategies, how is China addressing its reliance on coal and transitioning to renewable energy?
Ai Hui: In recent years, we have made substantial advancements in renewable energy installations, which is a positive sign for climate action. However, the current focus on energy security means that there may be a slowdown in our transition away from coal. It’s a complex balancing act, as we must ensure both immediate energy needs and long-term sustainability.
News Directory 3: what message would you like to convey to the public regarding these ongoing climate changes?
Ai Hui: I urge everyone to acknowledge the reality of climate change and its impacts. It’s crucial that we adapt and prepare for the shifting climate patterns while continuing to advocate for positive environmental policies. Collective action is essential to mitigate these changes and assure a sustainable future.
As Guangzhou continues to highlight the challenges posed by climate change, experts like Ai Hui provide invaluable insights to navigate this evolving landscape. Stay tuned to NewsDirectory3.com for ongoing coverage and analysis on climatic trends in China and beyond.
Research indicates that human-caused climate change drives more frequent and severe weather events. Events that occurred over the past decade would likely not have happened without global warming. In 2022, a heatwave in China led to record electricity use as people relied heavily on air conditioning, resulting in major power outages.
China’s leaders are now focused on energy security, which may slow the shift away from coal reliance. The country has made significant progress in renewable energy installations, signaling positive action on climate change.
