Northern Vietnam will experience thunderstorms starting from the middle of next week.

The heatwave in the North will end from July 2nd due to a low-pressure trough bringing showers and thunderstorms; mountainous areas should be wary of flash floods and landslides.

Over the past two days, the northern region has experienced widespread heat due to the influence of a low-pressure trough with its axis at approximately 24-26 degrees North latitude, connected to the circulation of a hot low-pressure area in the west. The National Center for Meteorological and Hydrological Forecasting predicts that temperatures of 35-37 degrees Celsius will persist until the end of today, July 1st.

The US website Accuweather forecasts Hanoi's highest temperature at the beginning of the week to be 37 degrees Celsius, dropping to 33 degrees from mid-week, with nighttime temperatures ranging from 27-29 degrees Celsius. High-altitude areas above 1,500 meters above sea level, such as Sa Pa (Lao Cai), will see a gradual decrease in temperature, reaching 18-20 degrees Celsius by the end of the week.

From July 2nd, the heatwave in Northern Vietnam will gradually subside due to the influence of a low-pressure trough moving from mainland China, bringing showers and thunderstorms. The heaviest rainfall will occur from July 2nd to 4th in the midland and mountainous areas of the North, and people should be wary of flash floods and landslides.

Central Vietnam is being affected by low-pressure systems and Foehn winds, so the hot weather will persist next week with maximum temperatures in the Thanh Hoa - Binh Dinh area reaching 36-38 degrees Celsius, and even exceeding 38 degrees Celsius in some places.

In Southern Vietnam and the Central Highlands, the southwest monsoon is moderately weak, so there will be little rain and sunny weather for the next two days. Forecasts indicate that from July 3rd onwards, the southwest monsoon will strengthen again, bringing widespread showers and thunderstorms to these two regions, mainly in the late afternoon and evening.

The highest temperatures in the Central Highlands will be 29-32 degrees Celsius, and in Southern Vietnam 32-34 degrees Celsius.
