The heat wave, which is moving from west to east, caused weekend temperatures in several northern and north-central mountainous localities to increase to 35-38 degrees Celsius.
On March 30, the temperature reached a high of 40 degrees Celsius in Tuong Duong (central Nghe An province), and 38.2 degrees Celsius in Huong Khe (central HaTinh province).
In the capital city of Hanoi, daily temperatures also rose to 29-31 degrees Celsius, with a high humidity level of 97%.
However, a cold spell will strike the north on April 1, causing regional temperatures to fall considerably.
Meanwhile, a heat wave has baked the southern region for the past few days, with daily temperatures ranging between 33 and 38 degrees Celsius.
