Atmospheric measurements including relative humidity, wind speed, and daylight duration mapped across the calendar year.
The climate profile for Muddy Mountains Wilderness provides a comprehensive twelve-month analysis of atmospheric conditions based on NASA POWER data. Spanning the period from 1991 to 2020, the record tracks average minimum and maximum temperatures, daily precipitation rates, and supporting humidity and wind metrics at a representative coordinate. These long-term averages establish a clear annual rhythm for the region, detailing how daylight and thermal patterns fluctuate throughout the months without relying on current forecasts.
