World Meteorological Day takes place on 23 March every year, commemorating the establishment of the World Meteorological Organization (WMO) on 23 March 1950. As a specialized agency of the United Nations, the WMO is dedicated to international cooperation and coordination on the state and behavior of the Earth’s atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resources.
World Meteorological Day showcases the essential contribution of National Meteorological and Hydrological Services to the safety and wellbeing of society. Under a specific theme each year, the day is celebrated through various activities around the world.
2022 Theme: Early Warning and Early Action
Weather, climate and water extremes are becoming more frequent and intense in many parts of the world as a result of climate change. More of us are exposed than ever before to multiple related hazards, which are themselves evolving as a result of population growth, urbanization and environmental degradation. Being prepared and able to act at the right time, in the right place, can save many lives and protect the livelihoods of communities everywhere, both now and in the future.
Under the theme “Early Warning and Early Action”, World Meteorological Day 2022 spotlights the vital importance of hydrometeorological and climate information for disaster risk reduction.
