World Meteorological Day

World Meteorological Day is a global observance dedicated to the work of meteorologists. Thanks to these specialists, people around the world can access accurate weather forecasts and prepare for changing conditions, whether that means bringing an umbrella or protecting themselves from extreme heat. The day is observed every year on March 23.

History

Modern meteorology has developed over many decades, with major scientific discoveries and technological advances improving the accuracy and availability of weather data. World Meteorological Day was established to mark the founding of the World Meteorological Organization (WMO), which officially came into force on March 23, 1950.

Meteorology plays a critical role not only in daily weather forecasting but also in long-term climate monitoring. Meteorologists help protect millions of people by identifying the conditions that lead to dangerous natural phenomena such as hurricanes, tornadoes, floods, and severe storms. When a threat is detected, authorities in affected areas are alerted so that preventive measures or evacuations can be organized in time.
