According to the National Center for Hydro-Meteorological Forecasting, from July to September 2026, the number of storms/tropical depressions operating in the East Sea and directly affecting Vietnam's mainland will be equivalent to the multi-year average (MPA).
Accordingly, the East Sea area is likely to have about 6-7 storms and tropical depressions. Among them, it is expected that there will be 2-3 storms directly affecting our mainland.
Providing information about weather trends in the coming months, Mr. Nguyen Duc Hoa - Deputy Head of the Climate Forecasting Department, National Center for Hydro-Meteorological Forecasting - said that the ENSO phenomenon has shifted to El Nino state, with sea surface temperatures in the central Pacific region about 0.9 degrees Celsius higher than the multi-year average.
According to the meteorological agency's assessment, under the impact of El Nino, the activity of storms and tropical depressions in the East Sea in the next 3 months will be equivalent to the multi-year average. In which, tropical depressions combined with Southwest monsoons can cause strong winds and big waves, affecting the operation of ships at sea.
In the last months of the year, El Nino is forecast to continue to be maintained and tend to strengthen gradually. Notably, the probability of El Nino appearing very strongly in the period from November 2026 to January 2027 may be up to 63%.
For the period from October to December 2026, the meteorological agency forecasts that the number of storms and tropical depressions operating in the East Sea and affecting the mainland will be lower than the multi-year average. However, the risk of strong winds and large waves appearing at sea is still present due to the impact of storms, tropical depressions, southwest monsoons and northeast monsoons.
From now until the end of 2026, there is a possibility of about 11 storms and tropical depressions appearing in the East Sea. Of which, about 4-5 storms may directly affect the mainland of Vietnam.
Previously, on the evening of June 3, the first tropical depression in the East Sea in 2026 formed. After operating at sea, this tropical depression moved out of the East Sea area and gradually weakened.
