According to forecaster Tran Thi Thuy Nga from the Weather Forecasting Department under the National Centre for Hydro-Meteorological Forecasting, most parts of the country, except the northeastern region, continued to experience hot conditions on April 9.

From April 10, the heat is likely to expand across the entire northern region. At the same time, central Vietnam will remain the focal point of this heatwave.

“The area stretching from Thanh Hoa to Hue will experience the most intense heat. Maximum temperatures are expected to range from 38 to 40°C, with some locations exceeding 40°C, particularly in the western mountainous areas of Nghe An, Ha Tinh and Quang Tri,” Nga said.

Compared to central Vietnam, other regions will see slightly less extreme temperatures, though conditions will remain hot.

In the northwest and areas from Da Nang to eastern Dak Lak, temperatures are expected to range from 35 to 37°C, with some places surpassing 37°C.

The northeastern region, including Hanoi, along with the Central Highlands and southern Vietnam, will record the lowest intensity of heat, with temperatures ranging between 35 and 36°C. However, actual temperatures outdoors may be 2 to 4°C higher, depending on surface conditions.

Meteorological authorities warn that this heatwave is likely to persist for several more days. The combination of high temperatures and low humidity is expected to have negative impacts on human health.

Experts advise people to limit outdoor activities during peak hours from 11am to 4pm, when ultraviolet radiation and temperatures reach their highest levels.

Authorities and residents are also urged to remain vigilant against the risk of fires and explosions in densely populated areas, as well as the heightened threat of forest fires.
