23rd March: World Meteorological Day

The United Nations (UN) World Meteorological Day is annually held on or around March 23 to remember the World Meteorological Organization’s establishment on that date in 1950. Many different activities and events are organized for this occasion.

Meteorological Day often features various events such as conferences, symposia, and exhibitions for meteorological professionals, community leaders, and the general public. Some events aim to attract media attention to raise meteorology’s profile.

Many prizes for meteorological research are presented or announced on or close to World Meteorological Day. The World Meteorological Day theme – The Ocean, our climate, and weather – celebrates WMO’s focus in connecting the ocean, climate, and weather within the Earth System. It also marks the starting year of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030).

Many countries issue postage stamps or special postage stamp cancellation marks to celebrate World Meteorological Day. These stamps often reflect the event’s theme or mark a country’s meteorology achievements.
