According to new weather forecasts from the Southern Hydrometeorological Station, in March and April, this area will still have some days of unseasonal thunderstorms. In April, seasonal rain will begin to appear and in the first week, mid-May week, the South is likely to enter the beginning of the rainy season.
Regarding weather patterns, in the next 3-10 days, a low pressure trough with an axis of about 25-28 degrees North latitude will be compressed and gradually move south under the impact of the continental high pressure from the North. Around the night of March 2nd and March 3rd, cold air is likely to be strengthened again, then continue to strengthen around March 5th and 6th, while the low pressure trough from the South will gradually weaken. This interaction is one of the reasons why unseasonal rain in the South will continue in the coming time.
Weather forecasts show that the Southern region, including Ho Chi Minh City, continues to experience unseasonal showers and thunderstorms accompanied by the risk of tornadoes, lightning, hail and strong gusts of wind. Extreme weather phenomena can cause trees to fall, affect houses, traffic infrastructure and agricultural production activities. In Ho Chi Minh City, unseasonal rain may suddenly appear in the late afternoon or night, with locally heavy rain.
In terms of hydrology, the water level on the Saigon River is forecast to decrease rapidly in the next 1-2 days, then increase again. By March 2nd, the peak tide at Phu An and Nha Be stations is at alarm level I, especially Thu Dau Mot station is approximately or above alarm level II, it is necessary to pay attention to the risk of flooding in low-lying areas when combined with heavy rain in Ho Chi Minh City.
According to monthly climate forecasts, from March 1st to 20th, 2026, the average temperature across the country is generally close to the multi-year average. The total rainfall nationwide tends to be equivalent to or higher than the multi-year average by about 10-30 mm, especially in some places exceeding 30 mm. Although it is the dry season, the South is still an area with a clear possibility of unseasonal rain.
In the context of the changing seasons, hot weather is still maintained in the Southeast and locally in the Southwest, increasing the risk of fires and explosions and local water shortages. The interweaving of hot weather and thunderstorms causes the weather in the South to fluctuate erratically in the coming time.
When traveling in the South and Ho Chi Minh City during this period, tourists should regularly follow weather forecasts, bring umbrellas or thin raincoats because unseasonal rain may appear suddenly. When sightseeing outdoors or traveling by motorbike, beware of thunderstorms, strong gusts of wind and the risk of localized flooding on low-lying roads after heavy rain.
