World Meteorological Day

World Meteorological Day History

World Meteorological Day highlights the work of meteorologists and hydrologists, focusing on their contributions to protect lives, property and the environment. Celebrated worldwide, this day benefits from a different theme each year, with topics often focusing on climate change, meteorological science innovation, extreme weather events and the sustainable use of natural resources.

World Meteorological Day is particularly significant within the United Kingdom due to its unpredictable weather patterns and susceptibility to extreme weather events. The observance, started by the World Meteorological Organisation (WMO) in 1961, honours the entry into force of the WMO Convention that established the Organization on the 23rd of March 1950. For those in the UK, the Met Office, which is a member of WMO, uses this day to draw attention to the importance of understanding weather patterns and forecasting. Through science and technology advancements, meteorologists today can better predict severe weather events, allowing societies to respond and prepare adequately.

In the UK, World Meteorological Day is typically observed with learning activities and awareness events that are often conducted by the Met Office. These may include webinars, workshops, displays and discussions aimed at the general public and meteorology communities. On this day, various stakeholders also come together to discuss the pressing climatic issues and global climate patterns. World Meteorological Day is celebrated on the 23rd of March each year, underlining our commitment to understand and predict the weather patterns to help safeguard our planet and its inhabitants.
