Northern Vietnam enters a new widespread heatwave.

From June 1st to 3rd, the northern region of Vietnam is likely to experience widespread heatwaves with maximum temperatures commonly reaching 35-36 degrees Celsius, and some areas experiencing intense heat exceeding 37 degrees Celsius.

According to the National Center for Meteorological and Hydrological Forecasting, from approximately June 1st to 3rd, the Northern region of Vietnam is likely to experience widespread heatwaves with maximum temperatures commonly reaching 35-36 degrees Celsius, and some areas experiencing intense heat exceeding 37 degrees Celsius.

Additionally, from approximately June 1st to 7th, the area from Thanh Hoa to Da Nang City and the eastern part of Quang Ngai province to Dak Lak will experience hot and intensely hot weather with maximum temperatures commonly ranging from 35 to 38 degrees Celsius, and in some places exceeding 38 degrees Celsius.

Following this heatwave, there may be 1-2 more heatwaves in June. These heatwaves could bring temperatures to 36-39°C, with some areas potentially exceeding 40°C (especially in the western mountainous regions of Thanh Hoa and Hue City). Generally, the temperature trend for June 2026 across the country is expected to be 0.5-1.0°C higher than the multi-year average, therefore the heatwaves in June 2026 will also be more intense than average.

With the trend of more frequent and intense heatwaves than the multi-year average, the risk of heatstroke, heat exhaustion, wildfires, residential fires, and localized water shortages may increase.

Representatives from the National Center for Meteorological and Hydrological Forecasting warn that prolonged high temperatures combined with low humidity significantly affect the health of the elderly, children, and outdoor workers. Furthermore, after heatwaves, there is often a potential risk of thunderstorms, lightning, and strong gusts of wind due to the conflict between hot air masses and weak cold air masses at the end of the season. People need to proactively take measures to protect themselves from the heat, use electricity safely, and regularly monitor weather forecasts and warnings of dangerous weather conditions.

Previously, on May 21st, a widespread heatwave began in the provinces from Quang Tri to Da Nang City, the eastern parts of the provinces from Quang Ngai to Dak Lak , and Khanh Hoa. On May 22nd, the heatwave expanded to the North Central provinces. On May 23rd, the heatwave continued to spread to the Northern provinces. This heatwave lasted until May 28th in the Northern and North Central provinces, and one day later in the provinces from Quang Tri to Da Nang City, and the eastern parts of the provinces from Quang Ngai to Dak Lak. The peak of this heatwave occurred between May 25th and 27th. From May 28th onwards, the heatwave gradually subsided in these areas.

Comparison with past data shows that: On May 25th and 26th, some stations recorded daily high temperatures exceeding historical values ​​(HGRs), such as: Uong Bi station (Quang Ninh) with a daily high temperature of 38°C, exceeding the HGR of 37.5°C on May 16th, 2013; Hiep Hoa station (Bac Ninh) with a daily high temperature of 39.7°C, exceeding the HGR of 39°C on May 19th, 2019; Bac Giang station with a daily high temperature of 39.4°C, exceeding the HGR of 39.1°C on May 21st, 2020; Hai Duong station (Hai Phong) with a daily high temperature of 39.8°C, exceeding the HGR of 39.6°C on May 21st, 2020; The Thai Binh weather station (Hung Yen province) recorded a maximum temperature of 38.5 degrees Celsius, exceeding the record high of 38.2 degrees Celsius on May 16, 2013.

The Northern Delta region, Phu Tho province, and the area from Thanh Hoa to Quang Tri experienced exceptionally intense heatwaves with absolute maximum temperatures commonly ranging from 39 to 41 degrees Celsius. Some locations recorded temperatures above 41 degrees, such as Lang (Hanoi) at 41.4 degrees Celsius (May 26th), Con Cuong (Nghe An) at 41.2 degrees Celsius (May 27th), and Do Luong (Nghe An) at 41.1 degrees Celsius (May 26th)...

In other areas of Northern Vietnam, the region from Hue City to Da Nang City and the eastern provinces from Quang Ngai to Dak Lak experienced intense heat with absolute maximum temperatures commonly ranging from 37 to 39 degrees Celsius. Some places experienced exceptionally intense heat exceeding 39 degrees, such as: Phu Yen (Son La) 40 degrees Celsius (May 27), Pho Rang (Lao Cai) 40.7 degrees Celsius (May 26), Bac Me and Hoang Su Phi (Tuyen Quang) 40.3 degrees Celsius (May 26), Tuy Hoa (Dak Lak) 40 degrees Celsius (May 26)...

From May 22nd to 27th, widespread heatwaves also occurred in the Southern region with daily maximum temperatures commonly ranging from 35 to 37 degrees Celsius. Some areas experienced intense heat exceeding 37 degrees, such as Tay Ninh (37.5 degrees Celsius on May 26th and 27th) and Bien Hoa (Dong Nai) (37.4 degrees Celsius on May 25th and 26th)...

According to the National Center for Meteorological and Hydrological Forecasting, this is a severe and exceptionally intense heatwave occurring over a wide area. For the same period in May, this heatwave is the strongest in the last five years (since 2021).

The distinctive feature of this heatwave is the long duration of sunshine throughout the day across all areas (starting at 9 am and lasting until 7 pm). At night, temperatures remain high at 30-31 degrees Celsius, making the heat stifling both day and night.

The cause of this heatwave is believed to be the influence of a strong and expanding hot low-pressure area in the West, extending its influence towards the Southeast, combined with a strong "Foehn" effect over the central provinces.
