In the Northern region, the Northwest experienced intense heat, with common temperatures of 35-37 degrees Celsius, and some areas exceeding 39 degrees. The highest temperature was recorded at 40,2 degrees Celsius in Phu Yen (Son La); some places like Muong Te (Lai Chau) and Lac Son (Phu Tho) approached 40 degrees.
In the Northern Delta, maximum temperatures generally ranged from 35-36 degrees Celsius. Lang station (Ha Noi) recorded 36 degrees, the highest since the beginning of the season; Hoai Duc saw 35 degrees, Ha Dong 34 degrees, and Ba Vi over 33 degrees. Nho Quan (Ninh Binh) exceeded 39 degrees, marking the highest in the delta region. Due to the urban heat island effect, actual perceived temperatures could be 2-4 degrees Celsius higher.
The North Central Coast was the epicenter of the heatwave, with common temperatures of 38-39 degrees Celsius, and some areas above 39 degrees. Many monitoring stations exceeded 41 degrees, including Quy Chau and Do Luong; Tay Hieu station alone reached nearly 42 degrees. In Ha Tinh, Huong Son and Huong Khe also recorded above 40 degrees.
The heatwave extended to the Central Central Coast, with Da Nang reaching 39 degrees and Quang Ngai 38 degrees; the Son Hoa area (Dak Lak) also hit 39 degrees Celsius.
According to the National Center for Hydro-Meteorological Forecasting, the cause is a hot low-pressure circulation from the West combined with a Foehn wind effect, leading to elevated temperatures, dry air, and an oppressive feeling. The Central Highlands and Southern region are influenced by a stable air mass, resulting in clear skies and strong sunshine.

Due to varying weather patterns, the intensity of the heat differs across regions. The Northwest and Central regions are experiencing dry heat, with some areas particularly intense, reaching temperatures of 37-39 degrees, while the Central region specifically exceeds 40 degrees. The Southern region maintains temperatures of 35-37 degrees, with prolonged sunshine but less intensity.
The widespread heatwave in the Northern region is forecast to last until around 12/4 before gradually decreasing. The Central region is likely to experience heat until 13-14/4. The Southern region's heat could extend until the end of April, though it will not be continuous, with intermittent cooler days.
US-based Accuweather forecasts Ha Noi to enter three peak days from 9/4, with temperatures ranging from 28-38 degrees, then dropping to 34-35 degrees. Areas above 1.500 m, such as Sa Pa (Lao Cai), will see temperatures fluctuate between 17-29 degrees until the weekend.
Meteorological agencies warn that intense heat combined with low humidity increases the risk of fires and explosions in residential areas due to high electricity demand, and can also cause dehydration from prolonged exposure to high temperatures.
