Detailed representative coordinate averages for temperature, precipitation, wind, and daylight across twelve months.
The climate profile for Ishi Wilderness provides a structured view of atmospheric variables based on NASA POWER records from 1991 to 2020. Data reflects monthly averages for temperature, precipitation, relative humidity, wind speed, and daylight duration measured at a single representative coordinate at an elevation of 469.79 meters. These long term averages illustrate the annual rhythm of conditions within the protected reserve, serving as a foundational resource for geographic climate analysis.
