Under the influence of a weak and easterly-leaning cold air front, northern Vietnam is experiencing consecutive days of rainfall, with localized heavy showers in mountainous regions.

Meanwhile, the Central, Central Highlands, and Southern regions continue to see sunny days and occasional showers at night, with particularly intense heat affecting the Southeast.

According to the National Center for Hydro-Meteorological Forecasting, as of April 5, scattered showers and thunderstorms have been recorded in the northern region.

Tonight and tomorrow (April 6), the northern mountains are expected to receive scattered rain and thunderstorms, with some areas experiencing heavy rainfall of 15–30mm, and possibly over 50mm in isolated locations.

Due to the ongoing impact of the weak, easterly cold air, more rain is forecast for mountainous areas from the night of April 6–7. Showers and scattered thunderstorms will continue, with localized heavy rain. From April 8 onward, rainfall is expected to subside, with morning fog in some areas and sunshine returning by midday.

From now through the night of April 7, the Red River Delta and North Central Coast will continue to see light rain or drizzle. From April 8, the region will experience light rain in some areas, accompanied by scattered morning fog or mist. In the lowland and coastal areas, light rain, drizzle, and fog are likely in the evening and early morning.

From April 8, the North Central region will see isolated light rain and morning fog, with sunnier conditions by midday. Between April 10–12, some areas may experience hot weather.

According to the forecast, Hanoi will face continuous light rain in the coming days, with fog expected on April 9. From April 10 onward, sunshine will return, but showers are still expected. As the cold air is weak, temperatures are not expected to drop significantly and are likely to rise quickly again.

From the Central Coast to the Southern region and Central Highlands, the weather pattern will remain unchanged, with showers and occasional thunderstorms in the evenings and nights, and hot sunny days. In the Southeast, hot weather is expected to intensify from April 8, becoming widespread and lasting through around April 10.

The national weather agency warns that thunderstorms across the country may be accompanied by whirlwinds, lightning, hail, and strong gusty winds.

Additionally, the Southern Regional Hydrometeorological Center reports increasing heat in Ho Chi Minh City, with temperatures reaching 34.4°C in Nha Be and up to 36°C at Tan Son Nhat.

Forecasts for April 6–7 indicate widespread heat in the region, with maximum daytime temperatures ranging from 35–37°C and minimum relative humidity between 40–45%. The hottest period will occur between 12:00 p.m. and 4:00 p.m.
