The World Meteorological Organisation (WMO) will hold an Extraordinary Congress from October 20 to 23, 2025, bringing together representatives from its 193 member states and territories to advance global cooperation in weather, water, and climate services.
The event, which coincides with the 75th anniversary of WMO as a United Nations specialised agency, will celebrate the organisation’s legacy of promoting the free exchange of meteorological data since 1950, a foundation for improved forecasts, warnings, and climate services that protect lives and support sustainable development.
A key focus of the Congress will be the Early Warnings for All (EW4All) initiative, launched by UN Secretary-General António Guterres in 2022.
The programme aims to ensure that everyone on Earth is protected by multi-hazard early warning systems by 2027.
Highlights include the high-level event “Bridging the Gaps: Turning Early Warning Ambition into Action” on October 20, featuring government leaders and the launch of the EW4All in Focus: Hazard Monitoring & Forecasting report.
The same day will also feature a side event on WMO’s Coordination Mechanism for humanitarian early warnings.
On October 21, discussions will turn to the role of artificial intelligence (AI) in weather forecasting, exploring ways to bridge the digital divide between developed and developing nations.
The Congress will culminate on October 22 with a special address by UN Secretary-General António Guterres, marking WMO’s milestone anniversary and reaffirming global commitment to early warning systems for all.
Congress sessions will be livestreamed on the WMO YouTube channel, and detailed agenda information is available on the WMO website.
