World Meteorological Organization (WMO) Calendar Competition 2021

World Meteorological Organization (WMO) Calendar Competition 2021

Deadline: September 15, 2020

Entries are invited for the World Meteorological Organization (WMO) Calendar Competition 2021. The World Meteorological Organization is looking for high-quality and artistic photographs, and especially those which illustrate the theme of World Meteorological Day 2021, “The Ocean, our climate and weather.”

The Ocean covers 70% of the Earth’s surface and provides resources on which the world depends. It is a major driver of the world’s weather and climate and stores more than 90% of excess heat generated by human activities. It provides endless fascination and inspiration for photographs which demonstrate its amazing beauty and  power and fragility. So the World Meteorological Organization hopes you will send them lots of images of the Ocean itself, as well as its effect on our climate and weather and water cycle. The opportunities are endless. As a U.N. agency, they are keen to encourage a good geographical balance which represents all regions.


  • Winning entries will feature in the WMO 2021 online calendar. They will be showcased on the WMO website and social media platforms and feature prominently in their World Meteorological Day 2021 celebrations.
  • They will also promote them among other U.N. agencies and showcase them during the UN Decade of Ocean Science for Sustainable Development to be held from 2021-2030.


  • Open to all individuals and groups, regardless of age or location.
  • Entrants under 18 years of age may participate with the permission of their parents or legal guardians. If the photo of an entrant under 18 years of age is chosen, and written parental or guardian permission cannot be provided, the WMO has the right to reject the entry.
