WMO 2024 Calendar Competition

The World Meteorological Organization is thrilled to announce the launch of its 2024 calendar photography competition. It is one of our most eagerly awaited annual activities. Each year becomes even more successful with an ever-increasing number of amazing photographs which illustrate the beauty, power and importance of weather, climate and water.

This year, the competition will reflect the theme of World Meteorological Day 2024: At the frontline of climate action.  

We are looking for high-quality and meaningful photographs that capture people and communities working on climate action and illustrate why the work of the WMO community is so important in protecting people from the forces of nature. We also want photos that illustrate the need to protect our planet from the impact of human activities.  

As a specialized agency of the United Nations, we are keen to encourage a geographical balance that represents all regions of the Earth. We are delighted that each year, we get new photos from new photographers from an increasing number of countries. 

Winning entries will feature in the printed WMO 2024 Calendar. They will be showcased on the WMO website and social media platforms and prominently in our World Meteorological Day 2024 celebrations. We will also promote them among other U.N. agencies. There will be lots of recognition but no financial reward!  

WMO will make an initial selection of outstanding photographs, based on technical and artistic merit. We will then publish shortlisted photos here on Facebook and Instagram, allowing our followers to vote for their favourites. The competition will also be promoted via TwitterLinkedIn, and other U.N. social media accounts.

Since its launch in 2014, the WMO Calendar Competition has gained stature and recognition. 

The United Nations regularly features your photos in its news stories and web pages. WMO’s website and social media channels also constantly promote our calendar entries. 

Some national meteorological and hydrological services also run their own photo contests and feed these entries to WMO. We are always looking to expand the competition and reach aspiring new photographers! 

WMO received more than 1 500 entries for the 2023 Calendar, and we thank everyone who participated. We look forward to the competition for the 2024 calendar. 

Judging criteria

Entries will be narrowed down to a shortlist by a WMO panel of experts in meteorology and hydrology as well as experienced professional photographers. Entries will be judged on: 

  • Technical quality, clarity, and composition
  • Visual impact
  • Novelty and flair for the unexpected
  • Illustration of the importance of climate action for people

WMO will make an initial selection of about 50 photographs, based on technical and artistic merit. We will then publish shortlisted photos on Facebook and Instagram, allowing our followers to vote for their favourites. The competition will also be promoted via Twitter and via other U.N. social media accounts.

The WMO jury will have the final say on the 13 photos for inclusion in the calendar (one for the cover and one for each month), based on the social media votes but also taking into account geographical balance.

All shortlisted photographs will be showcased on WMO web and social media channels. It is therefore important that you include your own social media handles so that we can credit you appropriately.
