US Climate Normals

The US Climate Normals are 30-year averages representing “normals” of the changing climate in the United States. They are calculated using climate observations obtained from local weather stations across the country. They are used to compare daily, monthly and annual climate conditions with what is deemed normal for a specific location. NOAA, a US agency tracking the US’ climate, released the new normal by calculating the average of 1991-2020. It is updated every decade.
