The North is scorching hot at 40°C but is unusually cool, experts explain

Over the past two weeks, the weather in the North has been constantly changing. On May 24, the area was affected by the Northeast monsoon, causing cold weather like the first days of winter, with heavy rains in many places causing localized flooding.

Experts explain the sudden change in the weather in the North these days when the weather was at its peak of over 40°C and then suddenly dropped sharply.

However, just a week later, on June 1-2, the temperature skyrocketed, the North entered a severe heat wave, in some places exceeding 40°C, the road surface burned like fire.

According to Mr. Nguyen Hong Sinh - Deputy Director of Hai Phong City Hydrometeorological Station, the cause of this sudden heat wave is due to the strong development of the low pressure area in the West, combined with the foehn effect, causing widespread heat in the North and Central regions, with some places being particularly severe.

Temperatures in some localities across the country on June 2.

On June 2, many meteorological stations across the country recorded high temperatures. Of which, Tuong Duong (Nghe An) recorded a temperature of 41.1°C; Lang station ( Hanoi ) 40.6°C; Phu Lien station (Hai Phong) 39.5°C.

In addition, other places also had high temperatures such as Bac Me (Ha Giang) with a temperature of 40.1°C; Dinh Lap (Lang Son) 37.8°C; Son Dong ( Bac Giang ) 39.8°C; Quang Ngai 39.6°C.

After two days of scorching heat, the North suddenly dropped nearly 10°C after receiving widespread thunderstorms, temporarily ending the heat wave. Today, the highest temperature in Hanoi is forecast to be around 32-34°C, other areas are generally 31-34°C, some places are over 34°C, some mountainous areas are down to 30°C.

"Today (June 3), the low pressure trough connecting with the hot low pressure area in the West is compressed and pushed south by the cold continental air mass in the North. Currently, the low pressure trough connecting with the hot low pressure area in the West passes through the North and has an axis through the North Central region.

Thus, with this situation, the heat wave in the North has ended. The heat wave in Nghe An and Ha Tinh will continue today." Mr. Sinh commented.

According to the National Center for Hydro-Meteorological Forecasting, in the afternoon and night of June 3, the North and North Central regions will have scattered showers and thunderstorms, locally heavy rain with rainfall of 15-30mm, some places over 80mm. During the day and night of June 3, the South will have showers and thunderstorms, some places heavy rain with rainfall of 20-40mm, some places over 80mm.

ENSO is expected to remain neutral until the end of November with a probability of 55–90%. From June to November 2025, storms and tropical depressions will operate in the East Sea and affect the mainland at approximately the multi-year average (the multi-year average in the East Sea is 11 storms, with 4.9 making landfall). National rainfall during this period will remain approximately the same as in many years.

On the morning of May 29, at a meeting with units on the upcoming flood situation, Mr. Mai Van Khiem - Director of the National Center for Hydro-Meteorological Forecasting, said that moderate and heavy rains are forecast to occur from June to August in the North, North Central, Central Highlands and South. In particular, the Central region will have increased rain from September to December. The heat will gradually decrease in the Central Highlands and South, while it will still persist in the North and Central regions until August 2025.
