This year, Vietnam can expect more moderate weather conditions, featuring hotter periods that will arrive later than typical along with above-average precipitation, as stated by the meteorological service.

The National Center for Hydro-Meteorological Forecasting has stated that from April through June, the ENSO climate event—known as the El Niño–Southern Oscillation, characterized by abnormally high sea surface temperatures in the central and eastern parts of the Pacific Ocean—is anticipated to remain neutral with a likelihood of 70-80%, affecting weather conditions across Vietnam.

Cold air waves will gradually weaken. Heatwaves in the northern and central regions will arrive later and be less intense than in previous years.

The temperatures in these regions are anticipated to rise starting from May.

In the Central Highlands and southern regions, heatwaves are forecast to begin later than usual in April bringing fewer days of extreme heat.

Generally, temperature levels throughout the nation will remain near their historical norms, with the exception of the northwestern region, where they could increase by 0.5-1 degrees Celsius higher than usual during May.

Even with the more favorable forecast, northern and central Vietnam will likely face extended periods of elevated heat during July and August, with conditions slowly improving as we move into September.

The wet season starting in April will result in substantial rainfall across the northern areas, north-central zones, Central Highlands, and southern parts of the region, with especially intense showers predicted for May and June.

It is anticipated that in the northern region, precipitation will be typical in April with amounts ranging from 70-120 mm in the flatlands and over 150 mm in the mountains.

In May, we can expect a rise in precipitation of around 5-10%.

In June, rainfall is expected to reach 250 mm, with certain elevated regions potentially getting up to 500 mm.

In the central area, precipitation in April should remain near average but might rise by 5-15% in May, totaling around 200 millimeters.

In the Central Highlands and southern areas, precipitation levels are expected to range from 5-15% higher than average during April and May.

From July through September, six storms are predicted to form over the East Sea, with three of them possibly reaching Vietnam’s shores.

In July and August, the northern region is expected to experience between 250-500 millimeters of rain. Precipitation levels for September should fall within the 150-250 millimeter range, consistent with typical amounts.

In the Central Highlands and southern regions, precipitation levels will range from 250 to 400 millimeters.

Vietnam endured
19 heatwaves last year
with temperatures surpassing long-term averages by 0.5-1.5 degrees Celsius.

On April 28, Dong Ha city in Vietnam’s central Quang Tri Province experienced a high of 44 degrees Celsius, marking the highest temperature observed in the month of April nationwide since 1976.

Last year, there were also 10 typhoons and one tropical depression recorded over the East Sea, out of which five made landfall.

Typhoon Yagi
was the most devastating, hitting Quang Nginh Province and Hai Phong City in the northern region with gusts of up to 166 km/h.

As Vietnam enters yet another uncertain year, officials caution that although severe heat might subside, the dangers posed by intense rainfall, storms, and floods continue to be significantly elevated.
