Widespread intense heat will continue across the Northern region until the end of tomorrow, 27/5, according to the National Center for Hydro-Meteorological Forecasting. The Northern Delta and Phu Tho province are expected to experience common highs of 38-40 degrees Celsius, with some areas exceeding 40 degrees. Other localities will see temperatures ranging from 36-38 degrees Celsius, with some also surpassing 40 degrees.

In the Central region, the heatwave is projected to last longer, until around 28/5, gradually easing from 29/5. The northern part of the Central region, from Thanh Hoa to Hue City, will be hotter, with typical temperatures of 38-40 degrees Celsius, and some spots exceeding 40 degrees. Da Nang and the eastern provinces from Quang Ngai to Lam Dong will experience temperatures between 36-38 degrees, with some areas reaching above 40 degrees Celsius.

Doctor Truong Ba Kien, Deputy Executive Director of the Center for Meteorological and Climate Research, Institute of Meteorology, Hydrology, Environment, and Sea, stated that the widespread heat in the Northern and Central regions will persist in the coming days. However, its intensity will gradually decrease from the evening of 27/5, as the weather pattern causing the heat weakens and the potential for localized thunderstorms increases in some areas.

Doctor Kien cautioned that a decrease in heat does not mean an immediate shift to cooler weather. Hanoi and many northern localities will maintain relatively high temperatures, commonly 30-31 degrees Celsius. Coupled with increased air humidity after thunderstorms, a muggy feeling may persist, especially in densely populated urban areas.

Accuweather forecasts Hanoi's temperature today will range from 30-43 degrees Celsius, dropping to 30-41 degrees Celsius tomorrow. After that, temperatures will gradually decrease by about one to two degrees daily, reaching approximately 26-35 degrees Celsius by the weekend. In Sa Pa (Lao Cai), temperatures of 19-28 degrees Celsius tomorrow could drop to 16-20 degrees Celsius by the weekend.

The meteorological agency warns that prolonged intense heat combined with low humidity increases the risk of explosions, fires in residential areas, and forest fires. The hot, dry weather can also cause dehydration, exhaustion, and heatstroke from prolonged exposure to high temperatures.

In response to this development, the Ministry of Agriculture and Environment has issued a document requesting provincial and city People's Committees (UBND) to strengthen forest fire prevention and control efforts. Localities should review high-risk fire areas and fully prepare personnel, vehicles, and equipment to respond when forest fires occur.

At the same time, localities must enhance public awareness campaigns and strictly control the use of fire in and near forests, especially slash-and-burn farming and clearing vegetation. When forest fires occur, authorities must promptly mobilize personnel and firefighting equipment, minimize damage, and strictly penalize violations according to regulations.

The Northern and Central regions are experiencing the second heatwave in 5/2026, which began on 23/5. The Northern Delta, Phu Tho, and the area from Thanh Hoa to Hue City have recorded intense and exceptionally intense heat, with common high temperatures of 38-40 degrees Celsius, and many areas exceeding 40 degrees Celsius. Yesterday, the hottest place nationwide was Vinh Yen (Phu Tho) at 40,8 degrees Celsius, followed by Hanoi (Lang station) at 40,7 degrees Celsius.

The cause of this heatwave, in addition to the influence of the hot low-pressure area from the west, is also affected by foehn winds, which make the air hotter and drier, with stronger thermal radiation. According to the meteorological agency, the intensity and duration of this heatwave are more severe than the 13-16/5 period, making it one of the three strongest heatwaves to occur in May since 2021.
