While celebrating the coming of the New Year, many South American countries are undergoing an unprecedented heatwave with the air temperature running to nearly 40 degrees Celsius, which has posed challenges to urban operations and public safety.
On Wednesday, in downtown Buenos Aires, the capital of Argentina, the outdoor ground temperature exceeded 42 degrees Celsius under the sun, and nearly 39 degrees Celsius even in the shade. Amid the persistent heat, the number of pedestrians on the streets noticeably decreased, with many choosing to seek refuge in air-conditioned indoor spaces.
According to weather forecasts, the current heatwave in Argentina may continue until early January 2026. The Argentine National Meteorological Service has issued a high-temperature warning, urging the public to avoid going out during midday and afternoon, stay hydrated, and take precautions against heatstroke.
"My blood pressure suddenly dropped while I was working yesterday, and I felt like I was about to faint. Luckily, someone came to help me, gave me some water, and I rested for a while before I recovered," said Bruno Sandoval, a local bicycle deliveryman.
The persistent heatwave has also affected how Argentinians celebrate the New Year's Day. Many families have chosen to stay indoors and have even changed their holiday diet to cope with the heat.
"We are trying to eat non-fatty foods now. In the past, we would often eat high-calorie snacks like candied nuts and sugar for the New Year holiday. But this time, we'll prepare plenty of fruit, drink lots of water, and try to avoid high-temperature environments even at night. We'll stay calm and patiently cope with the heat," said local resident Elina Figaro.
The wide use of air conditioners and fans led to a surge in pressure on the country's power grid. Late on Tuesday, a substation malfunction caused by an overloaded power grid triggered a massive power outage in the Argentine capital and surrounding areas, leaving over 40,000 households without power, including the presidential palace.
In Chile, the New Year holiday has also been accompanied by extreme heat. The capital, Santiago, and many central regions issued red heat warnings, with the government classifying the heatwave as an extreme weather event.
The combination of high temperatures and dry weather significantly increased the risk of forest fire, prompting authorities to enter a state of high alert and urging the public to avoid using open flames.
