Southern Vietnam braces for April heatwave, highs to reach 39 degrees Celsius

The center said temperatures across the south are on an upward trend this month, with hot conditions expanding across multiple localities.

Average temperatures are expected to rise from March and remain at or above long-term averages.

Daytime highs will generally range between 32 and 35 degrees Celsius, while some areas in the southeast may reach 36-39 degrees Celsius.

Rainfall is also set to increase as the region gradually transitions into the rainy season, which typically begins in early May.

April rainfall is likely to exceed March levels, with most areas expected to see six to 12 rainy days.

Lam Dong Province in the Central Highlands may see more frequent showers, with 10-15 rainy days during the month.

The combination of intense heat and intermittent rain is likely to disrupt atmospheric patterns and heighten the risk of hazardous weather.

Authorities warned that such conditions could affect the environment, living conditions, infrastructure, and socio-economic activities.

In early April, heat is expected to persist across the southeastern region, with some areas facing particularly severe conditions, while the Mekong Delta in the southwest will also see high temperatures.

Maximum temperatures during this period are forecast to range between 35 and 37 degrees Celsius, with some locations exceeding 37 degrees Celsius.

The heatwave is expected to persist in the coming days, with the natural disaster risk level due to heat remaining at level 1.

Low humidity associated with the heat increases the risk of fires and explosions in residential areas, as well as forest fires.

Prolonged exposure to high temperatures may lead to dehydration, exhaustion, and heatstroke, posing a risk to public health.
