The hot spell will first affect north-western and north-central localities on March 30, with temperatures climbing to 33-35°C, according to the National Centre of Hydro-meteorological Forecasting.

In Hanoi, temperatures will rise by 9 to 10°C, reaching 35°C on April 1 - 2.

The hot spell is forecast to last until April 4 due to the influence of low air pressure coming from the west.

Meanwhile, the southern region, including Ho Chi Minh City, is enduring a prolonged heat wave which is anticipated to last for a couple of days.

Daytime temperatures will stay high at between 35 - 37°C, or even above 37°C in some places, with humidity falling to a low of 45%.

Doctors warn that the searing heat could potentially threaten the health of the people, especially children and the elderly, as well as labourers working outdoors. They advise that adults keep children in airy homes during hot days, be fully vaccinated, and maintain a clean living area.
