National Weather Observers Day – May 4, 2025

National Weather Observers Day is on May 4. With their observations and weather reports, many people assist the National Weather Service to achieve its purpose of preserving life and property. SKYWARN, Cooperative (Co-Op) Observers, CoCoRaHS (Community Collaborative Rain, Hail, and Snow Network), and the general public are all part of this network. 

History of National Weather Observers Day

Alan Brue, who studied psychology at the State University of New York, invented the day on May 4, 1989. This day was developed for weather amateurs and professionals to honor their passion for the weather. Every year on May 4, this day is commemorated for those who enjoy viewing different weather phenomena.

With their sightings and weather reports, many individuals and groups assist the National Weather Service in fulfilling its objective of protecting people and property. 

As a volunteer, you can be a part of the CoCoRaHS Observers Team, which is available to anyone ready to work on measuring and mapping precipitation. In this program, you will receive all of the necessary equipment and training on how to measure and map precipitation and how to prepare reports.

It’s simple to set up; get a rain gauge, hang it outside during the rainy season, check the rain in the gauge, and report your findings on the National Weather Service’s website.

The major goal of this day is to emphasize the importance of professionals who work in weather services 24 hours a day, seven days a week, to warn people about approaching storms and other weather changes. A thousand weather observations are made every day by weather spotters and weather stations all around the world.

These observations give crucial information that warns the public about impending storms from all three locations; land, sea, and air. They also aid in a better understanding of weather events and the analysis of historical data.
