With Hanoi enduring yet another heat wave, temperatures throughout the capital are forecast to rise to 39 degrees Celsius in the coming days.

Hot weather returns to Hanoi 

According to the National Center for Hydro-Meteorological Forecasting, low pressure in the West extending to the Southeast on July 6, accompanied by the foehn effect, has caused another heat wave in northern and central regions.

Temperatures are therefore forecast to range between 34 and 37 degrees Celsius in northern localities, increasing to between 35 and 38 degrees Celsius from Thanh Hoa province to Phu Yen province.

With humidity levels expected to remain fairly low at between 50% and 60%, temperatures are anticipated to peak from 11am to 4pm each day, with highs of over 35 degrees Celsius.

Beginning from July 8, the hot spell is predicted to increase its intensity from Thanh Hoa to Quang Tri provinces, with temperature set to reach between 37 and 40 degrees Celsius. Indeed, some locations will even see temperatures exceed 40 degrees Celsius.

Elsewhere northern regions, including mountainous areas, are to be hit by similarly scorching temperatures on July 9, with the highest level ranging between 36 and 39 degrees Celsius.

Hanoi alone is forecast to see temperatures reach highs of between 35 to 37 degrees Celsius from July 6 to July 8, and between 36 and 39 degrees Celsius on July 9.

This bout of extreme weather is likely to be prolonged over the coming days.

Meteorologists have therefore issued a warning about an increased risk of forest fires in northern and central regions, in addition to fires in residential areas caused by an increasing demand for power consumption.

Moreover, the heat can cause numerous problems for people, including dehydration, exhaustion, and heat stroke due to prolonged exposure to high temperatures. With elderly people and children being particularly vulnerable, they are advised to drink more water, eat a healthy diet, and limit their travel when conditions are sunny.

Furthermore, the UV index in Hanoi and Da Nang on July 6 is between seven and nine, a level that could potentially harm those who are directly exposed to sunlight.

It is anticipated that showers will occur in the evening and throughout the night of July 6 in northern mountainous regions, with rainfall reaching between 20mm and 40mm over the course of 12 hours, increasing to more than 60mm over 12 hours in some locations. As such, mountainous provinces and the capital have been warned of the threat of whirlwinds, lightning, hail, and strong winds.
