Today, 27/9, northern Vietnam is under the influence of the southern edge of a low-pressure trough, centered around 26-28 degrees North latitude, resulting in predominantly dry weather. From now until the end of September, this low-pressure trough will continue to dominate, bringing minimal rain, sunny skies, and peak temperatures of 33-35 degrees C. Some localized areas may experience hot conditions.

The National Center for Hydro-Meteorological Forecasting announced that a cold air mass, the first of the season, will move down from southern China around the evening of 30/9. From the afternoon and night of 30/9, northern Vietnam will become cloudy with showers and thunderstorms. Temperatures in early October are expected to drop below 33 degrees C.

Accuweather, an American weather service, forecasts Hanoi's temperatures to range from 27-36 degrees C for the first three days of the week. From thursday, daily temperatures will decrease by 2-3 degrees, reaching 22-28 degrees C by the weekend. High-altitude locations above 1,500 m, such as Sa Pa (Lao Cai), will see temperatures of 18-25 degrees C early in the week, dropping to 16-21 degrees C by the weekend.

The meteorological agency advises that during this transitional season, thunderstorms may be accompanied by tornadoes, whirlwinds, and strong gusts. Residents should exercise caution when traveling or engaging in outdoor activities during this period of changing weather.

In central Vietnam, recent rainfall was primarily linked to a tropical convergence zone and easterly winds. This tropical convergence zone has now dissipated, and easterly winds are weakening, leading to a rapid decrease in rain. Tonight and tomorrow, rain will mainly persist along the south central coast.

From 29/9 to 30/9, central Vietnam will experience less rain and sunny skies, with some areas potentially seeing hot conditions and peak temperatures of 35-36 degrees C. From early morning on 1/10, as the cold air influences the region, Thanh Hoa and Nghe An may experience showers and thunderstorms. The remaining central provinces will continue to have minimal rain and sunny weather, being less affected by the cold air mass.

Rainfall in the Central Highlands and southern Vietnam has also decreased following the dissipation of the tropical convergence zone. Next week, scattered showers and thunderstorms are expected primarily in the late afternoons and evenings, with no signs of a major rainfall event.

Peak temperatures in the Central Highlands will generally be 28-31 degrees C, while southern Vietnam will see 33-34 degrees C.
