According to the National Centre for Hydro-Meteorological Forecasting, average temperatures across the country from May to July are expected to be around 0.5 to 1.5 degrees Celsius higher than the long-term average.
Heatwaves in northern and central Vietnam are likely to intensify, while in the Central Highlands and southern regions, hot weather is expected to ease gradually from late May.
Truong Ba Kien, deputy executive director of the Meteorology and Climate Research Centre, said there is more than a 60 per cent chance that ENSO conditions will shift to El Nino during the summer of 2026 and could last until the end of the year.
He said the number of storms and tropical depressions in the East Sea affecting Vietnam this year is likely to remain close to the long-term average.
Historical data shows that the East Sea typically records around 12 to 13 storms each year, with six to seven affecting Vietnam.

During El Nino years, the number of storms and tropical depressions in the East Sea may decline, but there is a higher risk of stronger storms and more unpredictable paths.
“Even if the number of storms decreases, the risks during storm season remain very high,” Kien said.
