Son Dong (Bac Giang) experienced the highest temperature in northern Vietnam, exceeding 39°C.

The meteorological agency forecasts continued showers and thunderstorms tonight and tomorrow across northern Vietnam due to the low-pressure trough, concentrating in the mountainous and midland areas. Thanks to the rain, temperatures over the next two days will drop below the heatwave threshold (under 35°C).
Accuweather forecasts Hanoi's temperature tomorrow between 26-32°C, rising again to 28-36°C by the weekend. High-altitude areas above 1,500 m like Sa Pa (Lao Cai) will range from 20-26°C.
From 2/8 to 4/8, the low-pressure trough will weaken, causing the rain to cease and the heatwave to return to northern Vietnam.
The central region, located south of the low-pressure trough crossing northern Vietnam, combined with the foehn wind effect, will experience widespread hot weather from now until the end of the week. Temperatures in the Thanh Hoa - Hue area and the south-central coast will reach 35-37°C, with some areas exceeding 38°C.
The Central Highlands (Tay Nguyen) and southern Vietnam will continue to experience afternoon and evening showers and thunderstorms due to the moderate southwest monsoon. Daily high temperatures in the Central Highlands will be 29-31°C, and in southern Vietnam, 32-34°C.
