Extreme weather in the North: Severe heat, temperatures reaching 39-40°C

The highest temperature on May 25 in many Northern localities ranged from 36-39°C, in some places exceeding 39-40°C. In Hanoi, the highest temperature recorded was up to 38-39°C, sometimes even reaching 39.7°C at some monitoring stations. The sultry feeling is increased due to the relatively low humidity (only 40-50%).

Specific weather situation today:

– Northeast (Hanoi, Hai Phong, Bac Ninh, Hung Yen…): Hot and sunny days, intense heat, afternoon and night with localized showers and thunderstorms.

– Northwest region (Northwest, Hoa Binh, Phu Tho…): Severe heat, some places are especially intense with temperatures above 39°C.

– Evening and night: Many areas will experience scattered thunderstorms. During thunderstorms, you need to be careful of tornadoes, lightning, hail and strong winds.

This heat wave is expected to last until around May 27 before potentially easing thanks to increased thunderstorms.

Impact of extreme weather

Authorities advise people to limit going out between 10:00 a.m. and 4:00 p.m. Outdoor workers, the elderly, children and people with cardiovascular and respiratory diseases need special attention. Many localities have implemented water supply and shielding measures for students and workers.

Farmers are also advised to irrigate crops properly to avoid water shortage due to strong evaporation. The electricity industry is operating at maximum capacity to meet the increased demand for electricity due to air conditioners and fans.

This is one of the strongest heat waves since the beginning of summer 2026 in the North, reflecting the increasingly obvious trend of extreme weather due to climate change.

Northern people need to closely monitor weather forecasts from official channels to take timely response measures.
