Storm and tropical depression forecast
According to the forecast of climate trends in the period from November 11 to December 10, 2025 of the National Center for Hydro-Meteorological Forecasting (NCHMF), there is a possibility of 1-2 storms or tropical depressions appearing and possibly affecting the mainland of Vietnam (average of many years: 1.2 storms in the East Sea, 0.4 storms making landfall in Vietnam).
Meanwhile, the Philippine Meteorological Agency (PAGASA) forecasts that a low pressure will appear around November 21-27, with a path that sweeps across the southern Philippines and then enters the East Sea, and may approach the Vietnam area. The low pressure is assessed to have little chance of strengthening into a storm or tropical depression.
Forecast of heavy rain
Warning of the risk of widespread heavy rain in the area from South Quang Tri to Da Nang, from the East of Quang Ngai to Dak Lak and Khanh Hoa.
In the Central Highlands and the South, showers and thunderstorms may appear scattered, concentrated in November.
In terms of rainfall, the area from South Quang Tri to Lam Dong is likely to be 30-60% higher than the average of many years. The remaining regions are generally 10-30% higher, except for the North and the range from Thanh Hoa to North Quang Tri can be 10-30% lower.
Cold air forecast
The cold air mass is forecast to increase in both frequency and intensity in the coming month.
Due to the impact of cold air, the average temperature in the Northeast, from Thanh Hoa to Da Nang and the East of Quang Ngai tends to be 0.5-1 degrees Celsius lower than the average of many years. Other areas are also forecast to be around 0.5 degrees Celsius lower over the same period.
In the context of climate change increasing dangerous phenomena such as heavy rain concentrated in a short period of time, flash floods and landslides, people and tourists should closely monitor storm forecasts and low pressure forecasts in short-term weather reports.
Proactively updating warning information will help improve response capacity before storms, low pressure or extreme weather patterns occur.
