According to the weather forecast of the Vietnam National Center for Hydro-Meteorological Forecasting, the day and night of August 3 will have severe heat in the North and Central regions. The capital Hanoi has the lowest temperature from 27-29 degrees Celsius, the highest from 36-38 degrees Celsius. The Northwest has the lowest temperature from 25-28 degrees Celsius, some places below 24 degrees Celsius; the highest from 34-37 degrees Celsius, some places above 37 degrees Celsius; Lai Chau - Dien Bien region has 30-33 degrees Celsius.
In China, Chongqing City is also experiencing the most severe heat wave since the beginning of summer. For the past week, the afternoon temperature here has continuously exceeded 40 degrees Celsius, forcing the authorities to raise the heat sun warning to the highest level.
On August 3, the temperature in Chongqing is forecast to peak at 44 degrees Celsius - a rare level even for a city of nearly 32 million people known as the "fire zone" of China. Since the beginning of May, the number of days the city has recorded temperatures exceeding 35 degrees Celsius has doubled the average of many years.
"The waves are getting more and more terrible" - Ms. Luu Phuong Anh, 60 years old, lamented when avoiding the heat with about 100 retirees at a conditioned metro entrance. "Last night, I adjusted the air conditioner to 17 degrees Celsius but the room was still hot."
Not only the elderly, but also the young in Chongqing are looking for ways to adapt. Some choose to swim on the Yangtze River when the sun sets, while others gather in old bomb shelters, where the natural temperature is much cooler.
The severe heat is not limited to China. In Northern Europe, which is used to cold climates, countries such as Norway, Finland and Sweden are experiencing an unprecedented heat wave.
In Finland, temperatures have continuously exceeded 30 degrees Celsius for three consecutive weeks - the longest consecutive hot date since 1961, according to the Finnish Meteorological Institute. The country's Arctic region also recorded 13 days above 30 degrees Celsius in July. Even in Sweden, the town of Haparanda has had 14 consecutive days of 25 degrees Celsius or more - a record not seen in more than 100 years.
In Spain, the national meteorological agency AEMET confirmed that the second heat wave of the summer 2025 will start from August 3, peaking on August 5. Temperature in many areas of Andalusia and Extremadura is forecast to reach 45 degrees Celsius, while Madrid and the Central provinces will reach 40-42 degrees Celsius.
Meanwhile, the central United States and the Ohio region were lucky to enjoy a rare, pleasant weekend after six consecutive stressful weeks. Temperature dropped to around 26-27 degrees Celsius, creating an opportunity to cool down temporarily before the heat wave returns.
Climate experts warn that as climate change continues to increase, extreme heat waves like now will become more common, lasting longer and causing more severe impacts, especially in regions that have not yet prepared for hot burning such as Northern Europe.
