According to the National Center for Hydro-Meteorological Forecasting, from around March 30 to April 2, the northwest region and provinces from Thanh Hoa to Hue are likely to see widespread heat. Some areas may face severe heat, with daily maximum temperatures commonly ranging from 35-37°C and locally exceeding 38°C.

Notably, between March 30 and 31, the northern plains are forecast to experience widespread heat, with maximum daytime temperatures of 35-36°C and some places surpassing 36°C.

In Hanoi, temperatures during this period are expected to peak at around 36°C.

Experts say that under this forecast scenario, this will be the first heatwave of 2026 in these regions, arriving earlier than the long-term average.

The combination of high temperatures and low humidity is expected to increase the risk of fires and explosions in residential areas, as well as forest fires in mountainous regions. Prolonged exposure to extreme heat may also lead to dehydration, exhaustion, heatstroke and heat shock.

Meanwhile, the Southern Regional Hydro-Meteorological Center reported that on March 25, heat conditions were already recorded in central Ho Chi Minh City, with temperatures reaching 35°C at Tan Son Nhat and minimum humidity dropping to 39%.

In the next three days, widespread heat is expected to continue across Ho Chi Minh City, with maximum temperatures ranging from 35-36°C and some areas exceeding 36°C. The lowest relative humidity is forecast to remain between 35-50%, with peak heat typically occurring from 12pm to 3pm.
