Vietnam Weather Forecast: Rain In North, Heat In South

On April 5, 2025, residents of Northern Vietnam are bracing for a day of unpredictable weather, as the National Center for Hydro-Meteorological Forecasting has issued a warning for rain, scattered showers, and thunderstorms across the region. The forecast indicates that some areas may experience heavy rainfall, with expected totals ranging from 15 to 30 millimeters, and in certain locations, even exceeding 50 millimeters.

The situation is particularly concerning for the mountainous provinces in the north, where authorities are urging residents to prepare for the risk of flash floods on small rivers and streams, as well as landslides on slopes and localized flooding in low-lying areas. The combination of heavy rainfall and steep terrain could lead to hazardous conditions, prompting local officials to advise caution.

Meanwhile, in stark contrast, Southern Vietnam is set to endure a wave of heat as temperatures soar. The region is forecasted to experience hot sunny weather, with high temperatures typically ranging from 35 to 36 degrees Celsius, and some areas possibly exceeding 36 degrees Celsius. The relative humidity is expected to remain low, between 45 and 50 percent, contributing to a dry and muggy atmosphere. This hot spell is predicted to persist until around April 10, 2025.
