Midewin National Tallgrass Prairie Monthly Climate Normals and Representative Atmospheric Data

Name: Midewin National Tallgrass Prairie monthly climate normals
Creator: NASA POWER

The climate profile for Midewin National Tallgrass Prairie presents monthly averages derived from NASA POWER data for a representative coordinate at 198.51 meters elevation. These figures reflect long-term trends recorded between 1991 and 2020, capturing variations in temperature extremes, daily precipitation rates, and average wind speeds. Use these patterns to understand the annual meteorological rhythm of the region across all twelve months.
