About World Meteorological Day
World Meteorological Day takes place every March 23, marking the 1950 founding of the World Meteorological Organization, the UN agency that keeps national weather services talking to each other. The day honors the meteorologists, hydrologists, and forecasters whose work turns raw atmospheric data into the warnings that save lives during storms, floods, and heat waves.
Each year the WMO selects a theme, and recent topics have included early warning systems, oceans, and the frozen regions of the planet. Weather services worldwide open their doors with exhibitions, school visits, and public lectures, while awards for outstanding meteorological research and forecasting are announced on this date.
The day is a good reminder of how much modern life depends on shared science. Satellites, radar networks, and ocean buoys feed a global exchange that crosses borders daily, an early and successful example of international cooperation. Checking the forecast on your phone is the quiet end of a very long chain.

History of World Meteorological Day
The World Meteorological Organization traces its roots to the International Meteorological Organization, a loose network of national weather services founded in 1873. After the Second World War, member states agreed to restructure it as an intergovernmental body, and the convention creating the World Meteorological Organization came into force on March 23, 1950. The agency became a specialized agency of the United Nations the following year and later helped launch major scientific milestones, including the International Geophysical Year and early global climate research. World Meteorological Day has been celebrated on the anniversary date since 1961, growing into an annual showcase for forecasting advances and, increasingly, for climate science communication.
