Long-term annual averages for atmospheric conditions in Fresno County
Twelve-month climate profiles based on 1991 to 2020 NASA POWER records for a representative coordinate within Kaiser Wilderness. This data characterizes the annual rhythm of temperature, precipitation, humidity, wind speed, and daylight hours, providing a consistent reference for the local atmospheric environment. Every monthly figure represents long-term averages rather than current weather, forecasts, or widespread terrain variations.

Long-term thermal ranges and average daily precipitation cycles across all twelve months
Compare average temperature bounds, daily precipitation rates, humidity, wind, and calculated daylight across the calendar year.
