Malheur National Forest Annual Climate Patterns, Monthly Averages, and Atmospheric Data

The climate profile for Malheur National Forest documents monthly averages for temperature, precipitation, humidity, wind, and daylight across the annual cycle. Based on the 1991 to 2020 NASA POWER data set, these records characterize conditions at a representative coordinate. This overview provides quantitative insight into long-term climate normals rather than real-time weather, forecasts, or localized microclimate variations.
