The National Center for Hydro-Meteorological Forecasting has issued a weather trend forecast for the next month (from April 22 to May 20).
According to Mr. Nguyen Duc Hoa - Deputy Head of Climate Forecasting Department, National Center for Hydro-Meteorological Forecasting, the weather during the above forecast period will have many fluctuations because it is entering the transitional season.

Sir, the temperature across the country is increasing rapidly and cold air waves have gradually decreased. Is it forecasted that there will be more cold air waves in the next month?
- In April and May, the northeast monsoon is still active. In the immediate future, there will be a cold air mass affecting the weather in the Northern region in the last days of April.
This cold air mass has a weak intensity but will still cause scattered showers and thunderstorms, with some places having heavy rain in the North. The rain will be concentrated in the late afternoon and night. In May, cold air will gradually decrease in both intensity and frequency.
What is the forecast for the temperature trend from now until May and how will the heat develop, sir?
- Regarding temperature trends, in the next month, the temperature across the country will be approximately the same as the average of many years in the same period.
Hot weather tends to increase in almost all areas of the country; beware of severe heat in the Northwest and Central regions.
This year, hot weather and severe heat will still occur, but it is unlikely to be as extreme or surpass record levels as in 2024.
In the past month, there have been many thunderstorms and haillides across the country. Can you provide information on rainfall forecasts in the coming period?
- Total rainfall across the country is forecast to be approximately the same as the average of many years; in the Central Central and South Central regions, it is 10 - 30% lower than the average of many years in the same period.
During the transitional season, cold air compressing the low pressure trough in the north can cause showers and thunderstorms in the Northern region.
The southwest monsoon in the south is likely to operate from around mid-May 2025, causing increased showers and thunderstorms in the Central Highlands and the South.
There is a possibility of dangerous weather phenomena such as thunderstorms, tornadoes, lightning, hail and strong gusts of wind across the country.
With such a weather trend in the next month, what recommendations do you have for the people?
- With a shortage of rain and the possibility of increased heat and sun, there is a risk of drought, water shortage and a very high risk of fire and explosion, especially in the Central region. Therefore, it is necessary to develop a plan to prevent drought and forest fires nationwide, especially in the Central and Central Highlands provinces.
People should regularly update weather forecast information to prevent heatstroke and heatstroke, and protect their health. During the changing seasons, it is also necessary to be on guard against extreme phenomena such as thunderstorms, tornadoes, lightning, and hail.
Sincerely thank you!
