A low-pressure heat zone from the west is expanding, causing a new heatwave across the Northern and Central regions
Meteorological experts say, this low-pressure heat zone is expanding, causing intense heat in the North and Central regions.
On May 4, the Northwestern and Northeastern regions, including the capital of Hanoi, are not experiencing extreme heat, with temperatures not exceeding 35°C. Meanwhile, the North-Central and Central regions are about 1°C hotter.
However, from May 5 onwards, the North-Central and Central-Central regions will experience hot weather, with some areas under intense heat, where maximum temperatures are expected to range from 35–37°C, and some places will exceed 37°C. The lowest relative humidity is forecast to be around 50–55%.
Due to the combined effects of high temperatures and low humidity, there is a high risk of fires and explosions in residential areas as electricity usage rises, and a significant risk of forest fires. In addition, intense heat can cause dehydration, exhaustion, and heatstroke, especially with prolonged exposure to high temperatures.
The actual felt temperatures can differ by 2–4°C, sometimes more, depending on surface conditions such as concrete and asphalt.
Meteorologists indicate that widespread heatwaves in the Northern and Central regions typically occur from May through August. Heatwaves are expected to ease in the Central Highlands and Southern Vietnam from June to July.
Mai Van Khiem, director of the National Centre for Hydro-Meteorological Forecasting, says in 2025 temperatures in many areas may exceed historical averages. Particularly, the Northern and Central localities are predicted to experience severe heatwaves, posing serious health risks to the community.
In addition to the heat, drought and saltwater intrusion will also be major challenges in 2025. The Mekong Delta and Central regions are expected to continue facing severe water shortages, negatively affecting agricultural production and daily life.
