It is likely that the heat wave in 2025 will not be as severe and prolonged as in 2024.
According to the National Center for Hydro-Meteorological Forecasting (Department of Hydro-Meteorology, Ministry of Agriculture and Environment), the ENSO phenomenon is in neutral conditions and is likely to continue from April to June 2025. It is likely that the heat wave in 2025 will not be as severe and prolonged as in 2024.
In the immediate future, in April, heat waves will continue to appear in the Northwest and mountainous areas of the North - Central Central region, with less intense heat waves than in the same period in 2024. Also from this month, widespread heat waves are likely to appear in the Central Highlands and the South, later than the average of many years (TBNN), with fewer hot days (over 35 degrees Celsius) than in the same period in 2024.
In the North, the cold air will gradually decrease and from May 2025, the heat wave is likely to increase across the Northern and Central regions. The average temperature from April to June across the country is forecast to be approximately the same as the average. In May 2025, the Northwest region of the North will be 0.5-1 degree Celsius higher than the average for the same period.
It should be noted that April and May are transitional months. The meteorological and hydrological agency has stated that there is a possibility of dangerous weather phenomena such as thunderstorms, tornadoes, lightning, hail and strong gusts of wind occurring nationwide.
Rainfall will increase gradually in the coming months. In April 2025, there is a possibility of seasonal rains in the North, North Central, Central Highlands and South regions. Moderate and heavy rains will occur more frequently in May and June.
In the North, total rainfall in April is forecast to be 70-120mm (over 150mm in mountainous areas). In May, total rainfall is forecast to be 120-220mm (over 250mm in mountainous areas) - 5-10% higher than the average. In June, total rainfall is forecast to be 150-250mm (250-500mm in mountainous areas, over 500mm in some places).
In the Central region, total rainfall in May was also 5-15% higher than the average, generally from 100-200mm, and higher in some places. April and June were approximately the average, generally not exceeding 150mm.
In the Central Highlands and the South, the total rainfall in April is generally around 60-100mm, with the Southern Central Highlands being higher at 100-180mm. In May, rainfall will increase by 5-15% compared to the average for the same period with a common level of 150-250mm, higher in some places. In June, the total rainfall in localities will reach 200-300mm, higher in some places.
There is a possibility of 3 storms making landfall during the rainy season.
In the next 3 months, there may be storms/tropical depressions in the East Sea, but they are unlikely to make landfall in our country. Cold air waves, storms, tropical depressions and the Southwest monsoon are likely to cause strong winds and large waves, affecting the activities of ships.
There is a possibility of 3 storms making landfall in July-September 2025.
The heat in the North and Central regions will continue in July and August and gradually decrease in September.
During this period, storms/tropical depressions are active in the East Sea and directly affect the mainland at the same level as the average (about more than 6 storms and 3 landfalls). Storms, tropical depressions and strong southwest monsoons can cause large waves in the offshore area of the East Sea from 4-6m, in the coastal areas of the North, Central and Southeast, waves can be 2-4m high, in the sea area of Ca Mau - Kien Giang, waves can be 1.5-2.5m high during the strong southwest monsoon.
The Meteorological and Hydrological Agency noted that the coastal areas of the Southwest region, from the end of July to September, need to be on guard against unusually high sea levels causing sea dike erosion during the high tides combined with the strong southwest monsoon. Coastal areas of the Northern and North Central provinces need to be on guard against large waves combined with rising water due to the impact of the storm.
During this time, the tide level at Vung Tau station is low, so the coastal area of the Southeast is not affected by the Northeast monsoon. Therefore, there is little possibility of high tides causing flooding in low-lying areas.
