A heatwave is forecast to strike central Vietnam in the first half of this week, while rain and thunderstorms are likely to dampen northern and southern provinces, according to the National Center for Hydro-meteorological Forecasting.
Temperatures will reach 36 to 39 degrees Celsius in the central region over the next days, with a high of 40 degrees Celsius in some areas.
Mercury normally hovers around 30 degrees Celsius in tropical Vietnam.
The UV index in the region is expected to be at eight to 10 on Monday.
A UV index reading of 8 to 10 means very high risk of harm from unprotected sun exposure, according to the World Health Organization.

Meanwhile, showers accompanied by gusts and thunderstorms are forecast to occur in northern Vietnam, including Hanoi, from June 24 to 27.
The weather pattern will pose high risks of flashfloods and landslides in mountainous areas.
Between June 24 and 27, Ho Chi Minh City will remain hot during the day, with a high of 35 degrees Celsius.
Rain and thunderstorms, however, are likely to occur in the evening.
The rainy weather will also affect other provinces in southern Vietnam and the Mekong Delta during this period.
