WHY THIS DAY MATTERS

Why We Love National Weather Observers Day

Weather observation is an important job

Observing the weather is a vital profession that requires a great deal of skill and knowledge. Weather observers are constantly learning new techniques and equipment to be able to accurately report on the state of the atmosphere and make informed forecasts.

Weather observers help keep us safe

Weather observers provide important data to meteorologists and other scientists to help them forecast the weather and issue warnings for hazardous conditions. This is essential for keeping people safe from severe weather events, such as tornadoes, floods and blizzards.

Weather observations help us understand the climate

By studying long-term weather trends and patterns, we are able to better understand how our climate is changing over time. This helps us make more informed decisions about how best to protect our environment and slow down dangerous climate change.
