The National Center for Hydro-Meteorological Forecasting has forecasted seasonal weather trends (from January 2025 to June 2025).
Regarding the ENSO phenomenon, ENSO is currently in a neutral state, with the sea surface temperature standard deviation in the central equatorial Pacific region being lower than the multi-year average.
In the first 6 months of 2025, ENSO is likely to remain neutral.
Regarding dangerous weather conditions at sea, in the first three months of 2025, there is little possibility of storms/tropical depressions operating in the East Sea and affecting our country. According to the average data of many years, in the period of January - March, the number of storms/tropical depressions in the East Sea is 0.6, making landfall is 0.1.
In April 2025, storms/tropical depressions are unlikely to be active in the East Sea. From May to June 2025, storm/tropical depression activity in the East Sea and landfall will be at a level equivalent to the average of many years. According to the average of many years, in the period of May to June, there will be about 1.6 storms/tropical depressions in the East Sea, 0.3 of which will make landfall.
Previously, in 2024, 9 storms were recorded in the East Sea.
The oceanographic situation and coastal areas of the Central and Southern provinces need to be careful of big waves combined with rising water, which pose a high risk of causing riverbank and coastal erosion.
January - March 2025, large waves during strong northeast monsoons, lasting in early 2025, 2 - 3m high in coastal areas and 4 - 5m high in offshore areas of the North and Central East Sea.
Coastal erosion continues to be complicated, especially during high tides combined with strong monsoons.
From January 2025 to March 2025, there will be 5 high tides in the Southeast coastal area.
From April to June 2025, the northeast monsoon weakens, while the southwest monsoon begins to operate, especially in the South China Sea. Waves in the sea from Binh Dinh to Ninh Thuan can reach 2-3m. In the Gulf of Thailand, waves commonly range from 0.5 - 1.5m.
From April to June 2025, water levels fluctuated in the coastal area of the Southeast, including Ho Chi Minh City and neighboring provinces, with 5 high tides.
Low-lying areas at coastal estuaries and coastal areas affected by high tides in coastal provinces in the Southeast region are at risk of flooding.
In addition, high tides also cause saltwater intrusion deep into river branches, affecting water resources and agricultural production.
