About World Meteorological Day

Every 23 March, the World Meteorological Organization commemorates the coming into force of the Convention establishing the World Meteorological Organization on 23 March 1950.

It showcases the essential contribution of National Meteorological and Hydrological Services to the safety and wellbeing of society and is celebrated with activities around the world. The themes chosen for World Meteorological Day reflect topical weather, climate or water-related issues.

2024 Theme: On the Frontline of Climate Action

The work of the WMO community is indispensable to climate action and to the Sustainable Development Goals across the board. The work is of huge societal importance: reducing hunger and poverty; improving health and well-being; ensuring clean water and affordable and clean energy; protecting life below the water and life on land; and making our cities and communities more resilient to climate change. 

Weather and climate predictions help boost food production and move closer to zero hunger. Integrating epidemiology and climate information helps understand and manage diseases sensitive to climate. And early-warning systems help to reduce poverty by giving people the chance to prepare and limit the impact of extreme weather. 

WMO, its Members, and its partners drive the full value cycle, from science to services to action for the good of society. It advances knowledge of our Earth system, monitors the state of the climate and water resources, provides scientific information to inform greenhouse gas emissions reductions and delivers climate services and early warnings to support climate adaptation.

Science is central to solutions and can supercharge progress on the SDGs across the board. We are united in science. WMO will remain at the Frontline of Climate Action as we embrace a journey of cooperation and innovation, leveraging collective expertise to overcome challenges and achieve our shared vision of a safer, more resilient world for future generations.

World Meteorological Day 2024 Geneva Celebration

The World Meteorological Day celebration will put the spotlight on climate action. The ceremony embraces all the key players involved in tackling the climate crisis: the UN family, national meteorological and hydrological services, youth and civil society, policy makers and the private sector.

This year, the World Meteorological Organization (WMO) is partnering with the UN Development Programme to launch a climate action campaign to raise awareness globally and mobilize society to act. The message of the campaign is about ambition, commitment and action from both policy makers and from individuals. If we all join together, we can keep the 1.5° degree ambition alive.

Join the launch live webcast on 21 March 2024 from 15:00 CET.
