Heatwave Sweeps Across Vietnam as Temperatures Climb to 37°C

Vietnam is entering its first major heatwave of the year, with temperatures rising sharply across the north, central, and southern regions in the final days of March and early April.

Meteorological authorities warn that this early season heat event could signal a more intense and prolonged summer compared to last year.

Northern regions: Rapid warming after storms

Northern Vietnam began the day with widespread showers and thunderstorms due to a moving wind convergence zone. However, conditions shifted بسرعة as sunshine returned by midday, pushing temperatures upward.

From March 30 onward, the northwest will experience the first wave of intense heat, with temperatures ranging from 34°C to 37°C. By the end of March, the heat is expected to expand across the Red River Delta, including Hanoi.

Although temperatures may ease slightly from April 1, humid and uncomfortable conditions will persist.

Central region: Highest temperatures expected

Central Vietnam is forecast to experience the most severe conditions.

From Thanh Hoa to Hue, temperatures are expected to reach 35°C to 37°C, with some areas exceeding 38°C. The heatwave in this region is likely to last longer than in the north, extending into early April before gradually subsiding.

Southern region: Persistent heat and low rainfall

Southern Vietnam, particularly the southeast, is already experiencing sustained high temperatures.

Over the coming week, the region will see widespread heat between 35°C and 37°C, combined with minimal rainfall. The Central Highlands will also remain hot, though slightly cooler at 33°C to 35°C.

A hotter than usual summer ahead

Forecasts indicate that heatwaves will expand further from April into May, eventually covering most of northern and central Vietnam. Peak intensity is expected during the summer months from June to August.

Meteorologists warn that 2026 could see more frequent and severe heat events compared to 2025, increasing the risk of extreme weather and associated impacts on health, agriculture, and energy demand.

The bottom line

This early widespread heatwave marks the beginning of a challenging seasonal cycle.

For residents and businesses alike, preparation for prolonged high temperatures and potential climate related disruptions will be essential in the months ahead.
