The National Center for Hydro-Meteorological Forecasting (NCHMF) is Vietnam’s national source of weather, climate, hydrological and marine forecasts and disaster warnings. Through its website, the center provides public information for communities, agencies and other users who need to monitor changing environmental conditions and prepare for potential hazards.

Its forecasts cover land and marine weather, daily conditions, outlooks for the next ten days, monthly and seasonal climate trends, and specialized climate information. The center also issues alerts for storms and tropical depressions, heavy rain, cold air, heat, thunderstorms, lightning, strong winds and other dangerous weather. Hydrological services include river-flow and water-resource updates, flood and flash-flood warnings, landslide and land-subsidence risks, drought and saltwater intrusion forecasts, and information supporting reservoir operations. Marine reporting addresses tides, sea-level surges, waves and currents.

NCHMF also publishes disaster-risk assessments, scientific and technical information, research updates, and meteorological and hydrological consultancy services. Its regularly updated bulletins help users follow developing conditions across Vietnam and make informed decisions.
