The cold spell struck early on April 5 and then quickly spread across the northern and north-central regions that put an end to searing heat in early summer, according to the National Centre for Hydro-meteorological Forecasting.

On April 5-6, the intense heat, especially in Son La, Hoa Binh, Thanh Hoa, Thua Thien-Hue, Da Nang and Phu Yen, will gradually turn down, with temperatures anticipated to fall 3 to 4°C, ranging from 25 to 35°C.

In Hanoi, the cold air wave also brought winds and rain to the capital early on April 5, causing temperatures to fall slightly and stay around 26 - 32°C.

Though temperatures drop slightly, people should be wary of thunderstorms and hailstones to hit the regions, warned meteorologists.

The experts also said in April 2024, northern localities are likely to endure cold air but with weak intensity, while low pressure in the West tends to become stronger, so hot weather will increase more in the northern and north-central regions.

The average temperature across the country is expected to be commonly 1-2 degrees higher than the average for many years during the same period.

As Vietnam is the transition period from the cold season to the hot season, erratic weather patterns such as thunderstorms and hailstones may occur more often across the country, warned meteorologists.
