According to the Northern Vietnam Meteorological and Hydrological Station, on May 26th, Hanoi experienced intense and exceptionally intense heat. At 1 PM, temperatures recorded at the Lang Meteorological Station reached 40°C, Ha Dong 39.2°C, Son Tay 39°C, Ba Vi 38.9°C, and Hoai Duc 38.8°C; humidity levels ranged from 39-42%.

Due to the influence of the southern edge of the low-pressure trough connected to the compressed and gradually filling hot low-pressure area in the West, Hanoi continued to experience intense heat on May 27th, with some areas experiencing exceptionally severe heat. Maximum temperatures generally reached 38-40 degrees Celsius; humidity remained relatively low, at 38-43%. The period of intense heat and temperatures above 35 degrees Celsius lasted from 9 am to 7 pm in the city center.

In particular, central Hanoi areas such as Ba Dinh, Hoan Kiem, Thanh Xuan, and Ha Dong... experienced the highest temperatures of 38-40 degrees Celsius; while northern and western communes generally saw temperatures of 37-39 degrees Celsius.

Notably, from the evening of May 27th to May 28th, many areas in the city experienced showers and thunderstorms, possibly accompanied by tornadoes, lightning, hail, and strong gusts of wind.

On May 28th, the intensity of the heatwave in Hanoi tended to decrease, with maximum temperatures generally ranging from 35-37 degrees Celsius. From the night of May 28th to May 30th, due to the influence of a compressed low-pressure trough combined with upper-level wind convergence, Hanoi's weather was cloudy, with scattered showers and thunderstorms in the evening and night, and occasional sunshine during the day. The heatwave in Hanoi ended on May 29th.

The meteorological agency notes that the temperature forecast in heatwave reports and the actual temperature felt outdoors can differ by 2 to 4 degrees Celsius, or even more, depending on the surface conditions such as concrete or asphalt. Prolonged intense heat combined with low humidity increases the risk of fires and explosions in residential areas due to increased electricity demand; it can also cause dehydration, exhaustion, and heatstroke from prolonged exposure to high temperatures.

To protect their health, people should limit their time outdoors between 10 am and 5 pm; ensure adequate hydration, and wear sun-protective clothing when traveling or working outdoors. People should also be wary of thunderstorms following the prolonged heatwave, which may be accompanied by tornadoes, lightning, hail, and strong winds.
