Public life

World Meteorological Day is a global observance and not a public holiday.

Background

The International Meteorological Organization was established at the first International Meteorological Congress in Vienna, Austria, in 1873. The organization aimed to establish meteorological station networks. These networks were linked by telegraph and improved weather forecasts. This contributed to shipping services' safety and efficiency.

The International Meteorological Organization became the World Meteorological Organization on March 23, 1950. It became the UN's specialized agency for meteorology, operational hydrology and related geophysical sciences in 1951.

The World Meteorological Organization plays a crucial role in contributing to people's safety and welfare. Its work is important in providing food security, water resources and transport. World Meteorological Day has been observed on March 23 each year since 1961.
