Modoc National Forest Climate Profile: Twelve Month Averages and Atmospheric Data Patterns

Name: Modoc National Forest monthly climate normals
Creator: NASA POWER

Access detailed monthly climate normals for Modoc National Forest, calculated from NASA POWER satellite data for the 1991 to 2020 period. Measurements include average minimum, mean, and maximum temperatures, along with daily precipitation, relative humidity, wind speed, and daylight hours for each month of the year. Values represent a single representative coordinate at 1446.8 meters in elevation, reflecting long term climatological patterns rather than current weather or site wide conditions.
